--- _id: '802' abstract: - lang: eng text: Glycoinositolphosphoceramides (GIPCs) are complex sphingolipids present at the plasma membrane of various eukaryotes with the important exception of mammals. In fungi, these glycosphingolipids commonly contain an alpha-mannose residue (Man) linked at position 2 of the inositol. However, several pathogenic fungi additionally synthesize zwitterionic GIPCs carrying an alpha-glucosamine residue (GlcN) at this position. In the human pathogen Aspergillus fumigatus, the GlcNalpha1,2IPC core (where IPC is inositolphosphoceramide) is elongated to Manalpha1,3Manalpha1,6GlcNalpha1,2IPC, which is the most abundant GIPC synthesized by this fungus. In this study, we identified an A. fumigatus N-acetylglucosaminyltransferase, named GntA, and demonstrate its involvement in the initiation of zwitterionic GIPC biosynthesis. Targeted deletion of the gene encoding GntA in A. fumigatus resulted in complete absence of zwitterionic GIPC; a phenotype that could be reverted by episomal expression of GntA in the mutant. The N-acetylhexosaminyltransferase activity of GntA was substantiated by production of N-acetylhexosamine-IPC in the yeast Saccharomyces cerevisiae upon GntA expression. Using an in vitro assay, GntA was furthermore shown to use UDP-N-acetylglucosamine as donor substrate to generate a glycolipid product resistant to saponification and to digestion by phosphatidylinositol-phospholipase C as expected for GlcNAcalpha1,2IPC. Finally, as the enzymes involved in mannosylation of IPC, GntA was localized to the Golgi apparatus, the site of IPC synthesis. author: - first_name: Jakob full_name: Engel, Jakob last_name: Engel - first_name: Philipp S full_name: Schmalhorst, Philipp S id: 309D50DA-F248-11E8-B48F-1D18A9856A87 last_name: Schmalhorst orcid: 0000-0002-5795-0133 - first_name: Anke full_name: Kruger, Anke last_name: Kruger - first_name: Christina full_name: Muller, Christina last_name: Muller - first_name: Falk full_name: Buettner, Falk last_name: Buettner - first_name: Françoise full_name: Routier, Françoise last_name: Routier citation: ama: Engel J, Schmalhorst PS, Kruger A, Muller C, Buettner F, Routier F.

Recent studies show that these proteins have common traits even at the monomer level. Among them, a polyglutamine region that is present in huntingtin is known to exhibit a correlation between the length of the chain and the severity as well as the earliness of the onset of Huntington disease. Here, we apply bias exchange molecular dynamics to generate structures of polyglutamine expansions of several lengths and characterize the resulting independent conformations. We compare the properties of these conformations to those of the standard proteins, as well as to other homopolymeric tracts. We find that, similar to the previously studied polyvaline chains, the set of possible transient folds is much broader than the set of known-to-date folds, although the conformations have different structures. We show that the mechanical stability is not related to any simple geometrical characteristics of the structures. We demonstrate that long polyglutamine expansions result in higher mechanical stability than the shorter ones. They also have a longer life span and are substantially more prone to form knotted structures. The knotted region has an average length of 35 residues, similar to the typical threshold for most polyglutamine-related diseases. Similarly, changes in shape and mechanical stability appear once the total length of the peptide exceeds this threshold of 35 glutamine residues. We suggest that knotted conformers may also harm the cellular machinery and thus lead to disease. acknowledgement: 'We acknowledge the support by the EU Joint Programme in Neurodegenerative Diseases (JPND AC14/00037) project.

Here, we identify a unique prototypic amoeboid cell migration mode in early zebrafish embryos, termed stable-bleb migration. Stable-bleb cells display an invariant polarized balloon-like shape with exceptional migration speed and persistence. Progenitor cells can be reversibly transformed into stable-bleb cells irrespective of their primary fate and motile characteristics by increasing myosin II activity through biochemical or mechanical stimuli. Using a combination of theory and experiments, we show that, in stable-bleb cells, cortical contractility fluctuations trigger a stochastic switch into amoeboid motility, and a positive feedback between cortical flows and gradients in contractility maintains stable-bleb cell polarization. We further show that rearward cortical flows drive stable-bleb cell migration in various adhesive and non-adhesive environments, unraveling a highly versatile amoeboid migration phenotype. acknowledged_ssus: - _id: SSU acknowledgement: 'We would like to thank R.

In particular, it has demonstrated that the “tool-kit genes” essential for regulating developmental processes are not only highly conserved among species, but are also used as systems at various times and places in an organism to control distinct developmental events. Therefore, mutations in many of these tool-kit genes may cause congenital diseases involving morphological abnormalities. This link between genes and abnormal morphological phenotypes underscores the importance of understanding how cells behave and contribute to morphogenesis as a result of gene function. Recent improvements in live imaging and in quantitative analyses of cellular dynamics will advance our understanding of the cellular pathogenesis of congenital diseases associated with aberrant morphologies. In these studies, it is critical to select an appropriate model organism for the particular phenomenon of interest. acknowledgement: The authors thank all the members of the Division of Morphogenesis, National Institute for Basic Biology, for their contributions to the research, their encouragement, and helpful discussions, particularly Dr M.

This technique involves stretching a homogeneous or heterogeneous chain of reference proteins (single-molecule markers) in which one of them acts as host to the guest protein under study. The guest protein is grafted into the host through genetic engineering. It is expected that unraveling of the host precedes the unraveling of the guest removing ambiguities in the reading of the force-extension patterns of the guest protein. We study examples of such systems within a coarse-grained structure-based model. We consider systems with various ratios of mechanostability for the host and guest molecules and compare them to experimental results involving cohesin I as the guest molecule. For a comparison, we also study the force-displacement patterns in proteins that are linked in a serial fashion. We find that the mechanostability of the guest is similar to that of the isolated or serially linked protein. We also demonstrate that the ideal configuration of this strategy would be one in which the host is much more mechanostable than the single-molecule markers. We finally show that it is troublesome to use the highly stable cystine knot proteins as a host to graft a guest in stretching studies because this would involve a cleaving procedure. acknowledgement: Grant Nr. 2011/01/N/ST3/02475 author: - first_name: Mateusz full_name: Chwastyk, Mateusz last_name: Chwastyk - first_name: Albert full_name: Galera Prat, Albert last_name: Galera Prat - first_name: Mateusz K full_name: Sikora, Mateusz K id: 2F74BCDE-F248-11E8-B48F-1D18A9856A87 last_name: Sikora - first_name: Àngel full_name: Gómez Sicilia, Àngel last_name: Gómez Sicilia - first_name: Mariano full_name: Carrión Vázquez, Mariano last_name: Carrión Vázquez - first_name: Marek full_name: Cieplak, Marek last_name: Cieplak citation: ama: 'Chwastyk M, Galera Prat A, Sikora MK, Gómez Sicilia À, Carrión Vázquez M, Cieplak M.

Yet, little is known about the actual process of docking to cell receptors and transport dynamics after internalization. Here we performed single-particle studies of folic acid (FA) mediated CNT binding to human carcinoma cells and their transport inside the cytosol. In particular, we employed molecular recognition force spectroscopy, an atomic force microscopy based method, to visualize and quantify docking of FA functionalized CNTs to FA binding receptors in terms of binding probability and binding force. We then traced individual fluorescently labeled, FA functionalized CNTs after specific uptake, and created a dynamic 'roadmap' that clearly showed trajectories of directed diffusion and areas of nanotube confinement in the cytosol. Our results demonstrate the potential of a single-molecule approach for investigation of drug-delivery vehicles and their targeting capacity. acknowledgement: "This work was supported by EC grant Marie Curie RTN-CT-2006-035616, CARBIO 'Carbon nanotubes for biomedical applications' and Austrian FFG grant mnt-era.net 823980, 'IntelliTip'.\r\n" article_number: '125704' article_processing_charge: No article_type: original author: - first_name: Constanze full_name: Lamprecht, Constanze last_name: Lamprecht - first_name: Birgit full_name: Plochberger, Birgit last_name: Plochberger - first_name: Verena full_name: Ruprecht, Verena id: 4D71A03A-F248-11E8-B48F-1D18A9856A87 last_name: Ruprecht orcid: 0000-0003-4088-8633 - first_name: Stefan full_name: Wieser, Stefan id: 355AA5A0-F248-11E8-B48F-1D18A9856A87 last_name: Wieser orcid: 0000-0002-2670-2217 - first_name: Christian full_name: Rankl, Christian last_name: Rankl - first_name: Elena full_name: Heister, Elena last_name: Heister - first_name: Barbara full_name: Unterauer, Barbara last_name: Unterauer - first_name: Mario full_name: Brameshuber, Mario last_name: Brameshuber - first_name: Jürgen full_name: Danzberger, Jürgen last_name: Danzberger - first_name: Petar full_name: Lukanov, Petar last_name: Lukanov - first_name: Emmanuel full_name: Flahaut, Emmanuel last_name: Flahaut - first_name: Gerhard full_name: Schütz, Gerhard last_name: Schütz - first_name: Peter full_name: Hinterdorfer, Peter last_name: Hinterdorfer - first_name: Andreas full_name: Ebner, Andreas last_name: Ebner citation: ama: Lamprecht C, Plochberger B, Ruprecht V, et al.

We discuss the stability of a cylindrical elastic shell and its response to a localized change in internal active stress. This description is relevant to describe the cellular actomyosin cortex, a thin shell at the cell surface behaving elastically at a short timescale and subjected to active internal forces arising from myosin molecular motor activity. We show that the recent observations of cell deformation following detachment of adherent cells (Maître J-L et al 2012 Science 338 253-6) are well accounted for by this mechanical description. The actin cortex elastic and bending moduli can be obtained from a quantitative analysis of cell shapes observed in these experiments. Our approach thus provides a non-invasive, imaging-based method for the extraction of cellular physical parameters. article_number: '065005' author: - first_name: Hélène full_name: Berthoumieux, Hélène last_name: Berthoumieux - first_name: Jean-Léon full_name: Maître, Jean-Léon id: 48F1E0D8-F248-11E8-B48F-1D18A9856A87 last_name: Maître orcid: 0000-0002-3688-1474 - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 - first_name: Ewa full_name: Paluch, Ewa last_name: Paluch - first_name: Frank full_name: Julicher, Frank last_name: Julicher - first_name: Guillaume full_name: Salbreux, Guillaume last_name: Salbreux citation: ama: Berthoumieux H, Maître J-L, Heisenberg C-PJ, Paluch E, Julicher F, Salbreux G.

In order to resolve the apparent contradictions between embryological and paleontological evidence a variety of hypotheses have been presented in recent years. The proposals range from excluding birds from the dinosaur clade, to assignments of homology by different criteria, or even assuming a hexadactyl tetrapod limb ground state. At present two approaches prevail: the frame shift hypothesis and the pyramid reduction hypothesis. While the former postulates a homeotic shift of digit identities, the latter argues for a gradual bilateral reduction of phalanges and digits. Here we present a new model that integrates elements from both hypotheses with the existing experimental and fossil evidence. We start from the main feature common to both earlier concepts, the initiating ontogenetic event: reduction and loss of the anterior-most digit. It is proposed that a concerted mechanism of molecular regulation and developmental mechanics is capable of shifting the boundaries of hoxD expression in embryonic forelimb buds as well as changing the digit phenotypes. Based on a distinction between positional (topological) and compositional (phenotypic) homology criteria, we argue that the identity of the avian digits is II, III, IV, despite a partially altered phenotype. Finally, we introduce an alternative digit reduction scheme that reconciles the current fossil evidence with the presented molecular-morphogenetic model. Our approach identifies specific experiments that allow to test whether gene expression can be shifted and digit phenotypes can be altered by induced digit loss or digit gain.' author: - first_name: Daniel full_name: Capek, Daniel id: 31C42484-F248-11E8-B48F-1D18A9856A87 last_name: Capek orcid: 0000-0001-5199-9940 - first_name: Brian full_name: Metscher, Brian last_name: Metscher - first_name: Gerd full_name: Müller, Gerd last_name: Müller citation: ama: 'Capek D, Metscher B, Müller G.

Regional differences in cell shape within the lumen-lining KV epithelium are essential for its LR patterning function. However, the processes by which KV cells acquire their characteristic shapes are largely unknown. Here, we show that the notochord induces regional differences in cell shape within KV by triggering extracellular matrix (ECM) accumulation adjacent to anterior-dorsal (AD) regions of KV. This localized ECM deposition restricts apical expansion of lumen-lining epithelial cells in AD regions of KV during lumen growth. Our study provides mechanistic insight into the processes by which KV translates global embryonic patterning into regional cell shape differences required for its LR symmetry-breaking function. acknowledgement: We are grateful to members of the C.-P.H. lab, M.

In order to gain insight into the biophysical mechanism(s) underlying the tissue morphogenesis we studied the spreading of an epithelium during the early development of the zebrafish embryo. In zebrafish epiboly the enveloping cell layer (EVL), a simple squamous epithelium, spreads over the yolk cell to completely engulf it at the end of gastrulation. Previous studies have proposed that an actomyosin ring forming within the yolk syncytial layer (YSL) acts as purse string that through constriction along its circumference pulls on the margin of the EVL. Direct biophysical evidence for this hypothesis has however been missing. The aim of the thesis was to understand how the actomyosin ring may generate pulling forces onto the EVL and what cellular mechanism(s) may facilitate the spreading of the epithelium. Using laser ablation to measure cortical tension within the actomyosin ring we found an anisotropic tension distribution, which was highest along the circumference of the ring. However the low degree of anisotropy was incompatible with the actomyosin ring functioning as a purse string only. Additionally, we observed retrograde cortical flow from vegetal parts of the ring into the EVL margin. Interpreting the experimental data using a theoretical distribution that models the tissues as active viscous gels led us to proposen that the actomyosin ring has a twofold contribution to EVL epiboly. It not only acts as a purse string through constriction along its circumference, but in addition constriction along the width of the ring generates pulling forces through friction-resisted cortical flow. Moreover, when rendering the purse string mechanism unproductive EVL epiboly proceeded normally indicating that the flow-friction mechanism is sufficient to drive the process. Aiming to understand what cellular mechanism(s) may facilitate the spreading of the epithelium we found that tension-oriented EVL cell divisions limit tissue anisotropy by releasing tension along the division axis and promote epithelial spreading. Notably, EVL cells undergo ectopic cell fusion in conditions in which oriented-cell division is impaired or the epithelium is mechanically challenged. Taken together our study of EVL epiboly suggests a novel mechanism of force generation for actomyosin rings through friction-resisted cortical flow and highlights the importance of tension-oriented cell divisions in epithelial morphogenesis. acknowledged_ssus: - _id: SSU alternative_title: - IST Austria Thesis author: - first_name: Martin full_name: Behrndt, Martin id: 3ECECA3A-F248-11E8-B48F-1D18A9856A87 last_name: Behrndt citation: ama: Behrndt M.

Here, we found that the glia of the Drosophila larval brain display an essential non-autonomous role during the development of the optic lobe. The optic lobe develops from neuroepithelial cells that proliferate by dividing symmetrically until they switch to asymmetric/differentiative divisions that generate neuroblasts. The proneural gene lethal of scute (l9sc) is transiently activated by the epidermal growth factor receptor (EGFR)-Ras signal transduction pathway at the leading edge of a proneural wave that sweeps from medial to lateral neuroepithelium, promoting this switch. This process is tightly regulated by the tissue-autonomous function within the neuroepithelium of multiple signaling pathways, including EGFR-Ras and Notch. This study shows that the Notch ligand Serrate (Ser) is expressed in the glia and it forms a complex in vivo with Notch and Canoe, which colocalize at the adherens junctions of neuroepithelial cells. This complex is crucial for interactions between glia and neuroepithelial cells during optic lobe development. Ser is tissue-autonomously required in the glia where it activates Notch to regulate its proliferation, and non-autonomously in the neuroepithelium where Ser induces Notch signaling to avoid the premature activation of the EGFR-Ras pathway and hence of L9sc. Interestingly, different Notch activity reporters showed very different expression patterns in the glia and in the neuroepithelium, suggesting the existence of tissue-specific factors that promote the expression of particular Notch target genes or/and a reporter response dependent on different thresholds of Notch signaling. author: - first_name: Raquel full_name: Pérez Gómez, Raquel last_name: Pérez Gómez - first_name: Jana full_name: Slovakova, Jana id: 30F3F2F0-F248-11E8-B48F-1D18A9856A87 last_name: Slovakova - first_name: Noemí full_name: Rives Quinto, Noemí last_name: Rives Quinto - first_name: Alena full_name: Krejčí, Alena last_name: Krejčí - first_name: Ana full_name: Carmena, Ana last_name: Carmena citation: ama: Pérez Gómez R, Slovakova J, Rives Quinto N, Krejčí A, Carmena A.

A key challenge for epithelial tissues undergoing spreading is to increase their surface area without disrupting epithelial integrity. Here we show that orienting cell divisions by tension constitutes an efficient mechanism by which the enveloping cell layer (EVL) releases anisotropic tension while undergoing spreading during zebrafish epiboly. The control of EVL cell-division orientation by tension involves cell elongation and requires myosin II activity to align the mitotic spindle with the main tension axis. We also found that in the absence of tension-oriented cell divisions and in the presence of increased tissue tension, EVL cells undergo ectopic fusions, suggesting that the reduction of tension anisotropy by oriented cell divisions is required to prevent EVL cells from fusing. We conclude that cell-division orientation by tension constitutes a key mechanism for limiting tension anisotropy and thus promoting tissue spreading during EVL epiboly. acknowledged_ssus: - _id: PreCl - _id: Bio acknowledgement: 'This work was supported by the IST Austria and MPI-CBG ' author: - first_name: Pedro full_name: Campinho, Pedro id: 3AFBBC42-F248-11E8-B48F-1D18A9856A87 last_name: Campinho orcid: 0000-0002-8526-5416 - first_name: Martin full_name: Behrndt, Martin id: 3ECECA3A-F248-11E8-B48F-1D18A9856A87 last_name: Behrndt - first_name: Jonas full_name: Ranft, Jonas last_name: Ranft - first_name: Thomas full_name: Risler, Thomas last_name: Risler - first_name: Nicolas full_name: Minc, Nicolas last_name: Minc - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 citation: ama: Campinho P, Behrndt M, Ranft J, Risler T, Minc N, Heisenberg C-PJ.

By regulating contact formation and stability, cadherins play a crucial role in tissue morphogenesis and homeostasis. Here, we review the three major unctions of cadherins in cell–cell contact formation and stability. Two of those functions lead to a decrease in interfacial ension at the forming cell–cell contact, thereby promoting contact expansion — first, by providing adhesion tension that lowers interfacial tension at the cell–cell contact, and second, by signaling to the actomyosin cytoskeleton in order to reduce cortex tension and thus interfacial tension at the contact. The third function of cadherins in cell–cell contact formation is to stabilize the contact by resisting mechanical forces that pull on the contact. author: - first_name: Jean-Léon full_name: Maître, Jean-Léon id: 48F1E0D8-F248-11E8-B48F-1D18A9856A87 last_name: Maître orcid: 0000-0002-3688-1474 - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 citation: ama: Maître J-L, Heisenberg C-PJ.

They are therefore integral to any morphogenetic processes. Force generation by actin-myosin networks and force transmission through adhesive complexes are two self-organizing phenomena driving tissue morphogenesis. Coordination and integration of forces by long-range force transmission and mechanosensing of cells within tissues produce large-scale tissue shape changes. Extrinsic mechanical forces also control tissue patterning by modulating cell fate specification and differentiation. Thus, the interplay between tissue mechanics and biochemical signaling orchestrates tissue morphogenesis and patterning in development. acknowledgement: C.-P.H. is supported by the Institute of Science and Technology Austria and grants from the Deutsche Forschungsgemeinschaft (DFG) and Fonds zur Förderung der wissenschaftlichen Forschung (FWF). author: - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 - first_name: Yohanns full_name: Bellaïche, Yohanns last_name: Bellaïche citation: ama: Heisenberg C-PJ, Bellaïche Y.

Development of organs containing motile cilia involves regulation of cilia formation (ciliogenesis) and formation of a luminal space (lumenogenesis) in which cilia generate fluid flows. Control of ciliogenesis and lumenogenesis is not yet fully understood, and it remains unclear whether these processes are coupled. In the zebrafish embryo, lethal giant larvae 2 (lgl2) is expressed prominently in ciliated organs. Lgl proteins are involved in establishing cell polarity and have been implicated in vesicle trafficking. Here, we identified a role for Lgl2 in development of ciliated epithelia in Kupffer's vesicle, which directs left-right asymmetry of the embryo; the otic vesicles, which give rise to the inner ear; and the pronephric ducts of the kidney. Using Kupffer's vesicle as a model ciliated organ, we found that depletion of Lgl2 disrupted lumen formation and reduced cilia number and length. Immunofluorescence and time-lapse imaging of Kupffer's vesicle morphogenesis in Lgl2-deficient embryos suggested cell adhesion defects and revealed loss of the adherens junction component E-cadherin at lateral membranes. Genetic interaction experiments indicate that Lgl2 interacts with Rab11a to regulate E-cadherin and mediate lumen formation that is uncoupled from cilia formation. These results uncover new roles and interactions for Lgl2 that are crucial for both lumenogenesis and ciliogenesis and indicate that these processes are genetically separable in zebrafish. acknowledgement: Deposited in PMC for release after 12 months.

The Wnt/planar cell polarity (Wnt/PCP) pathway orients mitosis in a number of developmental systems, including dorsal epiblast cell divisions along the animal-vegetal (A-V) axis during zebrafish gastrulation. How Wnt signalling orients the mitotic plane is, however, unknown. Here we show that, in dorsal epiblast cells, anthrax toxin receptor 2a (Antxr2a) accumulates in a polarized cortical cap, which is aligned with the embryonic A-V axis and forecasts the division plane. Filamentous actin (F-actin) also forms an A-V polarized cap, which depends on Wnt/PCP and its effectors RhoA and Rock2. Antxr2a is recruited to the cap by interacting with actin. Antxr2a also interacts with RhoA and together they activate the diaphanous-related formin zDia2. Mechanistically, Antxr2a functions as a Wnt-dependent polarized determinant, which, through the action of RhoA and zDia2, exerts torque on the spindle to align it with the A-V axis.\r\n" acknowledgement: This work was supported by the SNSF, the Swiss SystemsX.ch initiative and LipidX-2008/011 (M.G-G. and F.G.v.d.G.), by the Fondation SANTE-Vaduz/Aide au Soutien des Nouvelles Thérapies (F.G.v.d.G.) and by the ERC, the NCCR Frontiers in Genetics and Chemical Biology programmes and the Polish–Swiss research program (M.G-G.). author: - first_name: Irinka full_name: Castanon, Irinka last_name: Castanon - first_name: Laurence full_name: Abrami, Laurence last_name: Abrami - first_name: Laurent full_name: Holtzer, Laurent last_name: Holtzer - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 - first_name: Françoise full_name: Van Der Goot, Françoise last_name: Van Der Goot - first_name: Marcos full_name: González Gaitán, Marcos last_name: González Gaitán citation: ama: Castanon I, Abrami L, Holtzer L, Heisenberg C-PJ, Van Der Goot F, González Gaitán M.

Our current knowledge of cell polarisation in development is predominantly based on studies that have analysed polarisation of single cells, such as eggs, or cellular aggregates with a stable polarising interface, such as cultured epithelial cells (St Johnston and Ahringer, 2010). However, in embryonic development, particularly of vertebrates, cell polarisation processes often encompass large numbers of cells that are placed within moving and proliferating tissues, and undergo mesenchymal-to-epithelial transitions with a highly complex spatiotemporal choreography. How such intricate cell polarisation processes in embryonic development are achieved has only started to be analysed. By using live imaging of neurulation in the transparent zebrafish embryo, Buckley et al (2012) now describe a novel polarisation strategy by which cells assemble an apical domain in the part of their cell body that intersects with the midline of the forming neural rod. This mechanism, along with the previously described mirror-symmetric divisions (Tawk et al, 2007), is thought to trigger formation of both neural rod midline and lumen. author: - first_name: Julien full_name: Compagnon, Julien id: 2E3E0988-F248-11E8-B48F-1D18A9856A87 last_name: Compagnon - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 citation: ama: Compagnon J, Heisenberg C-PJ.

Here we use zebrafish epiboly as a model system to study the cellular and molecular mechanisms underlying the spreading of epithelial sheets. During zebrafish epiboly the enveloping cell layer (EVL), a simple squamous epithelium, spreads over the embryo to eventually cover the entire yolk cell by the end of gastrulation. The EVL leading edge is anchored through tight junctions to the yolk syncytial layer (YSL), where directly adjacent to the EVL margin a contractile actomyosin ring is formed that is thought to drive EVL epiboly. The prevalent view in the field was that the contractile ring exerts a pulling force on the EVL margin, which pulls the EVL towards the vegetal pole. However, how this force is generated and how it affects EVL morphology still remains elusive. Moreover, the cellular mechanisms mediating the increase in EVL surface area, while maintaining tissue integrity and function are still unclear. Here we show that the YSL actomyosin ring pulls on the EVL margin by two distinct force-generating mechanisms. One mechanism is based on contraction of the ring around its circumference, as previously proposed. The second mechanism is based on actomyosin retrogade flows, generating force through resistance against the substrate. The latter can function at any epiboly stage even in situations where the contraction-based mechanism is unproductive. Additionally, we demonstrate that during epiboly the EVL is subjected to anisotropic tension, which guides the orientation of EVL cell division along the main axis (animal-vegetal) of tension. The influence of tension in cell division orientation involves cell elongation and requires myosin-2 activity for proper spindle alignment. Strikingly, we reveal that tension-oriented cell divisions release anisotropic tension within the EVL and that in the absence of such divisions, EVL cells undergo ectopic fusions. We conclude that forces applied to the EVL by the action of the YSL actomyosin ring generate a tension anisotropy in the EVL that orients cell divisions, which in turn limit tissue tension increase thereby facilitating tissue spreading. acknowledged_ssus: - _id: Bio - _id: PreCl alternative_title: - ISTA Thesis article_processing_charge: No author: - first_name: Pedro full_name: Campinho, Pedro id: 3AFBBC42-F248-11E8-B48F-1D18A9856A87 last_name: Campinho orcid: 0000-0002-8526-5416 citation: ama: 'Campinho P.

Sanitary behavior, such as pathogen avoidance and removal, acts as a first line of defense to prevent infection [1] before activation of the physiological immune system. Insect societies have evolved a wide range of collective hygiene measures and intensive health care toward pathogen-exposed group members [2]. One of the most common behaviors is allogrooming, in which nestmates remove infectious particles from the body surfaces of exposed individuals [3]. Here we show that, in invasive garden ants, grooming of fungus-exposed brood is effective beyond the sheer mechanical removal of fungal conidiospores; it also includes chemical disinfection through the application of poison produced by the ants themselves. Formic acid is the main active component of the poison. It inhibits fungal growth of conidiospores remaining on the brood surface after grooming and also those collected in the mouth of the grooming ant. This dual function is achieved by uptake of the poison droplet into the mouth through acidopore self-grooming and subsequent application onto the infectious brood via brood grooming. This extraordinary behavior extends the current understanding of grooming and the establishment of social immunity in insect societies. acknowledgement: "Funding for this project was obtained by the German Research Foundation (DFG, to S.C.) and the European Research Council (ERC, through an ERC-Starting Grant to S.C. and an Individual Marie Curie IEF fellowship to L.V.U.).\r\nWe thank Jørgen Eilenberg, Bernhardt Steinwender, Miriam Stock, and Meghan L.

Actomyosin rings are generally thought to function by circumferential contraction. Here, we show that the spreading of the enveloping cell layer (EVL) over the yolk cell during zebrafish gastrulation is driven by a contractile actomyosin ring. In contrast to previous suggestions, we find that this ring functions not only by circumferential contraction but also by a flow-friction mechanism. This generates a pulling force through resistance against retrograde actomyosin flow. EVL spreading proceeds normally in situations where circumferential contraction is unproductive, indicating that the flow-friction mechanism is sufficient. Thus, actomyosin rings can function in epithelial morphogenesis through a combination of cable-constriction and flow-friction mechanisms. acknowledged_ssus: - _id: SSU author: - first_name: Martin full_name: Behrndt, Martin id: 3ECECA3A-F248-11E8-B48F-1D18A9856A87 last_name: Behrndt - first_name: Guillaume full_name: Salbreux, Guillaume last_name: Salbreux - first_name: Pedro full_name: Campinho, Pedro id: 3AFBBC42-F248-11E8-B48F-1D18A9856A87 last_name: Campinho orcid: 0000-0002-8526-5416 - first_name: Robert full_name: Hauschild, Robert id: 4E01D6B4-F248-11E8-B48F-1D18A9856A87 last_name: Hauschild orcid: 0000-0001-9843-3522 - first_name: Felix full_name: Oswald, Felix last_name: Oswald - first_name: Julia full_name: Roensch, Julia id: 4220E59C-F248-11E8-B48F-1D18A9856A87 last_name: Roensch - first_name: Stephan full_name: Grill, Stephan last_name: Grill - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 citation: ama: Behrndt M, Salbreux G, Campinho P, et al.

Here, we show that cell adhesion and cortex tension have different mechanical functions in controlling progenitor cell-cell contact formation and sorting during zebrafish gastrulation. Cortex tension controls cell-cell contact expansion by modulating interfacial tension at the contact. By contrast, adhesion has little direct function in contact expansion, but instead is needed to mechanically couple the cortices of adhering cells at their contacts, allowing cortex tension to control contact expansion. The coupling function of adhesion is mediated by E-cadherin and limited by the mechanical anchoring of E-cadherin to the cortex. Thus, cell adhesion provides the mechanical scaffold for cell cortex tension to drive cell sorting during gastrulation. acknowledged_ssus: - _id: SSU author: - first_name: Jean-Léon full_name: Maître, Jean-Léon id: 48F1E0D8-F248-11E8-B48F-1D18A9856A87 last_name: Maître orcid: 0000-0002-3688-1474 - first_name: Hélène full_name: Berthoumieux, Hélène last_name: Berthoumieux - first_name: Gabriel full_name: Krens, Gabriel id: 2B819732-F248-11E8-B48F-1D18A9856A87 last_name: Krens orcid: 0000-0003-4761-5996 - first_name: Guillaume full_name: Salbreux, Guillaume last_name: Salbreux - first_name: Frank full_name: Julicher, Frank last_name: Julicher - first_name: Ewa full_name: Paluch, Ewa last_name: Paluch - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 citation: ama: Maître J-L, Berthoumieux H, Krens G, et al.

Embryo morphogenesis relies on the interplay between different tissues, the properties of which are again determined by the interaction between their constituent cells. Cell interactions, on the other hand, are controlled by various molecules, such as signaling and adhesion molecules, which in order to exert their functions need to be spatiotemporally organized within and between the interacting cells. In this review, we will focus on the role of cell adhesion functioning at different scales to organize cell, tissue and embryo morphogenesis. We will specifically ask how the subcellular distribution of adhesion molecules controls the formation of cell-cell contacts, how cell-cell contacts determine tissue shape, and how tissue interactions regulate embryo morphogenesis. acknowledgement: This review comes from a themed issue on Cell structure and dynamics Edited by Jason Swedlow and Gaudenz Danuser author: - first_name: Vanessa full_name: Barone, Vanessa id: 419EECCC-F248-11E8-B48F-1D18A9856A87 last_name: Barone orcid: 0000-0003-2676-3367 - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 citation: ama: Barone V, Heisenberg C-PJ.

Increasing evidence indicates that E-cadherin adhesion molecules at the ZA serve to sense force applied on the junctions and coordinate cytoskeletal responses to those forces. Efforts to understand the role that cadherins play in mechanotransduction have been limited by the lack of assays to measure the impact of forces on the ZA. In this study we used 4D imaging of GFP-tagged E-cadherin to analyse the movement of the ZA. Junctions in confluent epithelial monolayers displayed prominent movements oriented orthogonal (perpendicular) to the ZA itself. Two components were identified in these movements: a relatively slow unidirectional (translational) component that could be readily fitted by least-squares regression analysis, upon which were superimposed more rapid oscillatory movements. Myosin IIB was a dominant factor responsible for driving the unilateral translational movements. In contrast, frequency spectrum analysis revealed that depletion of Myosin IIA increased the power of the oscillatory movements. This implies that Myosin IIA may serve to dampen oscillatory movements of the ZA. This extends our recent analysis of Myosin II at the ZA to demonstrate that Myosin IIA and Myosin IIB make distinct contributions to junctional movement at the ZA.' acknowledgement: his work was funded by the National Health and Medical Research Council (NHMRC) of Australia.

Single molecule experiments allow for resolving trajectories at extremely high spatial and temporal accuracy, thereby offering insights into en route interactions of the tracer. In this review we discuss approaches to derive information about the underlying processes, based on single molecule tracking experiments. In particular, we focus on a new versatile way to analyze single molecule diffusion in the absence of a full analytical treatment. The method is based on comprehensive comparison of an experimental data set against the hypothetical outcome of multiple experiments performed on the computer. Since Monte Carlo simulations can be easily and rapidly performed even on state-of-the-art PCs, our method provides a simple way for testing various - even complicated - diffusion models. We describe the new method in detail, and show the applicability on two specific examples: firstly, kinetic rate constants can be derived for the transient interaction of mobile membrane proteins; secondly, residence time and corral size can be extracted for confined diffusion.' author: - first_name: Verena full_name: Ruprecht, Verena id: 4D71A03A-F248-11E8-B48F-1D18A9856A87 last_name: Ruprecht orcid: 0000-0003-4088-8633 - first_name: Markus full_name: Axmann, Markus last_name: Axmann - first_name: Stefan full_name: Wieser, Stefan id: 355AA5A0-F248-11E8-B48F-1D18A9856A87 last_name: Wieser orcid: 0000-0002-2670-2217 - first_name: Gerhard full_name: Schuetz, Gerhard last_name: Schuetz citation: ama: Ruprecht V, Axmann M, Wieser S, Schuetz G.

Cohesion among neuroepithelial cells (NCs) has been suggested to function in FBMN migration by inhibiting FBMNs positioned in the basal neuroepithelium such that they move apically between NCs towards the midline of the neuroepithelium instead of tangentially along the basal side of the neuroepithelium towards r6/7. However, direct experimental evaluation of this hypothesis is still lacking. Here, we have used a combination of biophysical cell adhesion measurements and high-resolution time-lapse microscopy to determine the role of NC cohesion in FBMN migration. We show that reducing NC cohesion by interfering with Cadherin 2 (Cdh2) activity results in FBMNs positioned at the basal side of the neuroepithelium moving apically towards the neural tube midline instead of tangentially towards r6/7. In embryos with strongly reduced NC cohesion, ectopic apical FBMN movement frequently results in fusion of the bilateral FBMN clusters over the apical midline of the neural tube. By contrast, reducing cohesion among FBMNs by interfering with Contactin 2 (Cntn2) expression in these cells has little effect on apical FBMN movement, but reduces the fusion of the bilateral FBMN clusters in embryos with strongly diminished NC cohesion. These data provide direct experimental evidence that NC cohesion functions in tangential FBMN migration by restricting their apical movement. acknowledged_ssus: - _id: Bio - _id: PreCl article_type: original author: - first_name: Petra full_name: Stockinger, Petra id: 261CB030-E90D-11E9-B182-F697D44B663C last_name: Stockinger - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 - first_name: Jean-Léon full_name: Maître, Jean-Léon id: 48F1E0D8-F248-11E8-B48F-1D18A9856A87 last_name: Maître orcid: 0000-0002-3688-1474 citation: ama: Stockinger P, Heisenberg C-PJ, Maître J-L.

This mechanism spatially separates the germ layers and establishes the organizational foundation for future development. Mesodermal identity is specified in a superficial layer of cells, the epiblast, where cells maintain an epithelioid morphology. These cells involute to join the deeper hypoblast layer where they adopt a migratory, mesenchymal morphology. Expression of a cascade of related transcription factors orchestrates the parallel genetic transition from primitive to mature mesoderm. Although the early and late stages of this process are increasingly well understood, the transition between them has remained largely mysterious. We present here the first high resolution in vivo observations of the blebby transitional morphology of involuting mesodermal cells in a vertebrate embryo. We further demonstrate that the zebrafish spadetail mutation creates a reversible block in the maturation program, stalling cells in the transition state. This mutation creates an ideal system for dissecting the specific properties of cells undergoing the morphological transition of maturing mesoderm, as we demonstrate with a direct measurement of cell–cell adhesion. article_type: original author: - first_name: Richard full_name: Row, Richard last_name: Row - first_name: Jean-Léon full_name: Maître, Jean-Léon id: 48F1E0D8-F248-11E8-B48F-1D18A9856A87 last_name: Maître orcid: 0000-0002-3688-1474 - first_name: Benjamin full_name: Martin, Benjamin last_name: Martin - first_name: Petra full_name: Stockinger, Petra id: 261CB030-E90D-11E9-B182-F697D44B663C last_name: Stockinger - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 - first_name: David full_name: Kimelman, David last_name: Kimelman citation: ama: Row R, Maître J-L, Martin B, Stockinger P, Heisenberg C-PJ, Kimelman D.

Cell sorting involves both the segregation of a mixed population of cells with different fates and properties into distinct domains, and the active maintenance of their segregated state. Because of its biological importance and apparent resemblance to fluid segregation in physics, cell sorting was extensively studied by both biologists and physicists over the last decades. Different theories were developed that try to explain cell sorting on the basis of the physical properties of the constituent cells. However, only recently the molecular and cellular mechanisms that control the physical properties driving cell sorting, have begun to be unraveled. In this review, we will provide an overview of different cell-sorting processes in development and discuss how these processes can be explained by the different sorting theories, and how these theories in turn can be connected to the molecular and cellular mechanisms driving these processes. alternative_title: - Current Topics in Developmental Biology article_processing_charge: No author: - first_name: Gabriel full_name: Krens, Gabriel id: 2B819732-F248-11E8-B48F-1D18A9856A87 last_name: Krens orcid: 0000-0003-4761-5996 - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 citation: ama: 'Krens G, Heisenberg C-PJ.

Close to the trap center, this field is typically approximated as linear in the displacement of the trapped microsphere. However, applications demanding high forces at low laser intensities can probe the light-microsphere interaction beyond the linear regime. Here, we measured the full nonlinear force and displacement response of an optical trap in two dimensions using a dual-beam optical trap setup with back-focal-plane photodetection. We observed a substantial stiffening of the trap beyond the linear regime that depends on microsphere size, in agreement with Mie theory calculations. Surprisingly, we found that the linear detection range for forces exceeds the one for displacement by far. Our approach allows for a complete calibration of an optical trap. article_processing_charge: No author: - first_name: Marcus full_name: Jahnel, Marcus last_name: Jahnel - first_name: Martin full_name: Behrndt, Martin id: 3ECECA3A-F248-11E8-B48F-1D18A9856A87 last_name: Behrndt - first_name: Anita full_name: Jannasch, Anita last_name: Jannasch - first_name: Erik full_name: Schaeffer, Erik last_name: Schaeffer - first_name: Stephan full_name: Grill, Stephan last_name: Grill citation: ama: Jahnel M, Behrndt M, Jannasch A, Schaeffer E, Grill S.

The attachment of the plasma membrane to the underlying actomyosin cortex has been proposed to be important for cellular processes involving membrane deformation. However, little is known about the actual function of membrane-to-cortex attachment (MCA) in cell protrusion formation and migration, in particular in the context of the developing embryo. Here, we use a multidisciplinary approach to study MCA in zebrafish mesoderm and endoderm (mesendoderm) germ layer progenitor cells, which migrate using a combination of different protrusion types, namely, lamellipodia, filopodia, and blebs, during zebrafish gastrulation. By interfering with the activity of molecules linking the cortex to the membrane and measuring resulting changes in MCA by atomic force microscopy, we show that reducing MCA in mesendoderm progenitors increases the proportion of cellular blebs and reduces the directionality of cell migration. We propose that MCA is a key parameter controlling the relative proportions of different cell protrusion types in mesendoderm progenitors, and thus is key in controlling directed migration during gastrulation. acknowledgement: "We would like to thank A.

The stereotypical orientation of cell divisions has been proposed to be a fundamental mechanism by which proliferating and growing tissues take shape. However, the actual contribution of stereotypical division orientation (SDO) to tissue morphogenesis is unclear. In zebrafish, cell divisions with stereotypical orientation have been implicated in both body-axis elongation and neural rod formation [1, 2], although there is little direct evidence for a critical function of SDO in either of these processes. Here we show that SDO is required for formation of the neural rod midline during neurulation but dispensable for elongation of the body axis during gastrulation. Our data indicate that SDO during both gastrulation and neurulation is dependent on the noncanonical Wnt receptor Frizzled 7 (Fz7) and that interfering with cell division orientation leads to severe defects in neural rod midline formation but not body-axis elongation. These findings suggest a novel function for Fz7-controlled cell division orientation in neural rod midline formation during neurulation.

In vitro cell sorting studies have been instrumental in revealing the cellular properties driving this process. However, these studies have as yet been limited to two-dimensional analysis of three-dimensional cell sorting events. Here we describe a method to record the sorting of primary zebrafish ectoderm and mesoderm germ layer progenitor cells in three dimensions over time, and quantitatively analyze their sorting behavior using an order parameter related to heterotypic interface length. We investigate the cell population size dependence of sorted aggregates and find that the germ layer progenitor cells engulfed in the final configuration display a relationship between total interfacial length and system size according to a simple geometrical argument, subject to a finite-size effect. author: - first_name: Abigail full_name: Klopper, Abigail last_name: Klopper - first_name: Gabriel full_name: Krens, Gabriel id: 2B819732-F248-11E8-B48F-1D18A9856A87 last_name: Krens orcid: 0000-0003-4761-5996 - first_name: Stephan full_name: Grill, Stephan last_name: Grill - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 citation: ama: 'Klopper A, Krens G, Grill S, Heisenberg C-PJ.

Studies predominantly in cell culture showed that mechanosensation through adhesion structures is achieved by force-mediated modulation of their molecular composition. The specific molecular composition of adhesion sites in turn determines their signalling activity and dynamic reorganization. Here, we will review how adhesion sites respond to mecanical stimuli, and how spatially and temporally regulated signalling from different adhesion sites controls cell migration and tissue morphogenesis. acknowledged_ssus: - _id: Bio author: - first_name: Ekaterina full_name: Papusheva, Ekaterina id: 41DB591E-F248-11E8-B48F-1D18A9856A87 last_name: Papusheva - first_name: Carl-Philipp J full_name: Heisenberg, Carl-Philipp J id: 39427864-F248-11E8-B48F-1D18A9856A87 last_name: Heisenberg orcid: 0000-0002-0912-4566 citation: ama: 'Papusheva E, Heisenberg C-PJ.
