[{"abstract":[{"lang":"eng","text":"Most migrating cells extrude their front by the force of actin polymerization. Polymerization requires an initial nucleation step, which is mediated by factors establishing either parallel filaments in the case of filopodia or branched filaments that form the branched lamellipodial network. Branches are considered essential for regular cell motility and are initiated by the Arp2/3 complex, which in turn is activated by nucleation-promoting factors of the WASP and WAVE families. Here we employed rapid amoeboid crawling leukocytes and found that deletion of the WAVE complex eliminated actin branching and thus lamellipodia formation. The cells were left with parallel filaments at the leading edge, which translated, depending on the differentiation status of the cell, into a unipolar pointed cell shape or cells with multiple filopodia. Remarkably, unipolar cells migrated with increased speed and enormous directional persistence, while they were unable to turn towards chemotactic gradients. Cells with multiple filopodia retained chemotactic activity but their migration was progressively impaired with increasing geometrical complexity of the extracellular environment. These findings establish that diversified leading edge protrusions serve as explorative structures while they slow down actual locomotion."}],"type":"journal_article","file":[{"file_id":"7844","relation":"main_file","checksum":"e1411cb7c99a2d9089c178a6abef25e7","date_created":"2020-05-14T16:33:46Z","date_updated":"2020-07-14T12:44:43Z","access_level":"open_access","file_name":"2018_NatureCell_Leithner.pdf","creator":"dernst","file_size":4433280,"content_type":"application/pdf"}],"oa_version":"Submitted Version","intvolume":" 18","status":"public","ddc":["570"],"title":"Diversified actin protrusions promote environmental exploration but are dispensable for locomotion of leukocytes","_id":"1321","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","article_processing_charge":"No","has_accepted_license":"1","day":"24","scopus_import":1,"date_published":"2016-10-24T00:00:00Z","page":"1253 - 1259","article_type":"original","citation":{"mla":"Leithner, Alexander F., et al. “Diversified Actin Protrusions Promote Environmental Exploration but Are Dispensable for Locomotion of Leukocytes.” Nature Cell Biology, vol. 18, Nature Publishing Group, 2016, pp. 1253–59, doi:10.1038/ncb3426.","short":"A.F.

We have developed a theoretical description of genetic regulatory systems in bacteria that explicitly considers the cell division cycle to investigate its impact on gene expression. We calculate the cell-to-cell variations arising from cells being at different stages in the division cycle for unregulated genes and for basic regulatory mechanisms. These variations contribute to the extrinsic noise observed in single-cell experiments, and are most significant for proteins with short lifetimes. Negative autoregulation buffers against variation of protein concentration over the division cycle, but the effect is found to be relatively weak. Stronger buffering is achieved by an increased protein lifetime. Positive autoregulation can strongly amplify such variation if the parameters are set to values that lead to resonance-like behaviour. For cooperative positive autoregulation, the concentration variation over the division cycle diminishes the parameter region of bistability and modulates the switching times between the two stable states. The same effects are seen for a two-gene mutual-repression toggle switch. By contrast, an oscillatory circuit, the repressilator, is only weakly affected by the division cycle."}]},{"doi":"10.1016/j.cell.2015.01.056","date_published":"2015-04-09T00:00:00Z","language":[{"iso":"eng"}],"publication":"Cell","citation":{"chicago":"Maiuri, Paolo, Jean Rupprecht, Stefan Wieser, Verena Ruprecht, Olivier Bénichou, Nicolas Carpi, Mathieu Coppey, et al. “Actin Flows Mediate a Universal Coupling between Cell Speed and Cell Persistence.” Cell.

Various cell migration patterns have been reported, but no general rule has emerged so far. Here, we show on the basis of experimental data in vitro and in vivo that cell persistence, which quantifies the straightness of trajectories, is robustly coupled to cell migration speed. We suggest that this universal coupling constitutes a generic law of cell migration, which originates in the advection of polarity cues by an actin cytoskeleton undergoing flows at the cellular scale. Our analysis relies on a theoretical model that we validate by measuring the persistence of cells upon modulation of actin flow speeds and upon optogenetic manipulation of the binding of an actin regulator to actin filaments. Beyond the quantitative prediction of the coupling, the model yields a generic phase diagram of cellular trajectories, which recapitulates the full range of observed migration patterns."}],"ec_funded":1,"publist_id":"5618","issue":"2","type":"journal_article"},{"type":"journal_article","abstract":[{"lang":"eng","text":"Replication-deficient recombinant adenoviruses are potent vectors for the efficient transient expression of exogenous genes in resting immune cells.

How leukocyte migration and function are coordinated is unknown. Here we show that in immature dendritic cells, which patrol their environment by engulfing extracellular material, cell migration and antigen capture are antagonistic. This antagonism results from transient enrichment of myosin IIA at the cell front, which disrupts the back-to-front gradient of the motor protein, slowing down locomotion but promoting antigen capture. We further highlight that myosin IIA enrichment at the cell front requires the MHC class II-associated invariant chain (Ii). Thus, by controlling myosin IIA localization, Ii imposes on dendritic cells an intermittent antigen capture behaviour that might facilitate environment patrolling. We propose that the requirement for myosin II in both cell migration and specific cell functions may provide a general mechanism for their coordination in time and space."}],"_id":"1575","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 6","status":"public","ddc":["570"],"title":"Cell migration and antigen capture are antagonistic processes coupled by myosin II in dendritic cells","pubrep_id":"476","file":[{"date_updated":"2020-07-14T12:45:02Z","date_created":"2018-12-12T10:11:58Z","checksum":"bae12e86be2adb28253f890b8bba8315","file_id":"4915","relation":"main_file","creator":"system","file_size":4530215,"content_type":"application/pdf","file_name":"IST-2016-476-v1+1_ncomms8526.pdf","access_level":"open_access"}],"oa_version":"Published Version","scopus_import":1,"has_accepted_license":"1","day":"25","citation":{"ista":"Chabaud M, Heuzé M, Bretou M, Vargas P, Maiuri P, Solanes P, Maurin M, Terriac E, Le Berre M, Lankar D, Piolot T, Adelstein R, Zhang Y, Sixt MK, Jacobelli J, Bénichou O, Voituriez R, Piel M, Lennon Duménil A. 2015.

Inflammatory processes are often associated with an increased production of serotonin, which operates by activating specific receptors. However, the functional role of serotonin receptors in regulation of dendritic cell functions is poorly understood. Here, we demonstrate that expression of serotonin receptor 5-HT7 (5-HT7TR) as well as its downstream effector Cdc42 is upregulated in dendritic cells upon maturation. Although dendritic cell maturation was independent of 5-HT7TR, receptor stimulation affected dendritic cell morphology through Cdc42-mediated signaling. In addition, basal activity of 5-HT7TR was required for the proper expression of the chemokine receptor CCR7, which is a key factor that controls dendritic cell migration. Consistent with this, we observed that 5-HT7TR enhances chemotactic motility of dendritic cells in vitro by modulating their directionality and migration velocity. Accordingly, migration of dendritic cells in murine colon explants was abolished after pharmacological receptor inhibition. Our results indicate that there is a crucial role for 5-HT7TR-Cdc42-mediated signaling in the regulation of dendritic cell morphology and motility, suggesting that 5-HT7TR could be a new target for treatment of a variety of inflammatory and immune disorders."}],"type":"journal_article","author":[{"full_name":"Holst, Katrin","last_name":"Holst","first_name":"Katrin"},{"last_name":"Guseva","first_name":"Daria","full_name":"Guseva, Daria"},{"full_name":"Schindler, Susann","first_name":"Susann","last_name":"Schindler"},{"full_name":"Sixt, Michael K","orcid":"0000-0002-6620-9179","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","last_name":"Sixt","first_name":"Michael K"},{"last_name":"Braun","first_name":"Armin","full_name":"Braun, Armin"},{"first_name":"Himpriya","last_name":"Chopra","full_name":"Chopra, Himpriya"},{"full_name":"Pabst, Oliver","last_name":"Pabst","first_name":"Oliver"},{"last_name":"Ponimaskin","first_name":"Evgeni","full_name":"Ponimaskin, Evgeni"}],"oa_version":"None","volume":128,"date_updated":"2021-01-12T08:00:54Z","date_created":"2018-12-11T11:46:41Z","year":"2015","_id":"477","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","department":[{"_id":"MiSi"}],"publisher":"Company of Biologists","intvolume":" 128","title":"The serotonin receptor 5-HT7R regulates the morphology and migratory properties of dendritic cells","publication_status":"published","status":"public","month":"06","day":"15","scopus_import":1,"doi":"10.1242/jcs.167999","date_published":"2015-06-15T00:00:00Z","language":[{"iso":"eng"}],"citation":{"ama":"Holst K, Guseva D, Schindler S, et al.

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.","lang":"eng"}],"type":"journal_article","pubrep_id":"484","oa_version":"Published Version","file":[{"file_size":4362653,"content_type":"application/pdf","creator":"system","file_name":"IST-2016-484-v1+1_1-s2.0-S0092867415000094-main.pdf","access_level":"open_access","date_updated":"2020-07-14T12:45:01Z","date_created":"2018-12-12T10:13:21Z","checksum":"228d3edf40627d897b3875088a0ac51f","relation":"main_file","file_id":"5003"}],"_id":"1537","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","intvolume":" 160","ddc":["570"],"title":"Cortical contractility triggers a stochastic switch to fast amoeboid cell motility","status":"public"},{"date_created":"2018-12-11T11:54:30Z","date_updated":"2021-01-12T06:53:47Z","volume":514,"oa_version":"None","author":[{"full_name":"Sixt, Michael K","last_name":"Sixt","first_name":"Michael K","orcid":"0000-0002-6620-9179","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Vaahtomeri, Kari","id":"368EE576-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-7829-3518","first_name":"Kari","last_name":"Vaahtomeri"}],"publication_status":"published","status":"public","title":"Physiology: Relax and come in","department":[{"_id":"MiSi"}],"publisher":"Springer Nature","intvolume":" 514","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"1877","year":"2014","abstract":[{"text":"During inflammation, lymph nodes swell with an influx of immune cells.

The dynamic regulation of epithelial adhesion plays a decisive role in the life cycle of LCs. It controls whether LCs remain immature and sessile within the epidermis or mature and egress to initiate immune responses. So far, the molecular machinery regulating epithelial adhesion molecules during LC maturation remains elusive. Here, we generated pure populations of immature human LCs in vitro to systematically probe for gene-expression changes during LC maturation. LCs down-regulate a set of epithelial genes including E-cadherin, while they upregulate the mesenchymal marker N-cadherin known to facilitate cell migration. In addition, N-cadherin is constitutively expressed by monocyte-derived DCs known to exhibit characteristics of both inflammatory-type and interstitial/dermal DCs. Moreover, the transcription factors ZEB1 and ZEB2 (ZEB is zinc-finger E-box-binding homeobox) are upregulated in migratory LCs. ZEB1 and ZEB2 have been shown to induce epithelial-to-mesenchymal transition (EMT) and invasive behavior in cancer cells undergoing metastasis. Our results provide the first hint that the molecular EMT machinery might facilitate LC mobilization. Moreover, our study suggests that N-cadherin plays a role during DC migration.","lang":"eng"}],"citation":{"chicago":"Konradi, Sabine, Nighat Yasmin, Denise Haslwanter, Michele Weber, Bernd Gesslbauer, Michael K Sixt, and Herbert Strobl. “Langerhans Cell Maturation Is Accompanied by Induction of N-Cadherin and the Transcriptional Regulators of Epithelial-Mesenchymal Transition ZEB1/2.” European Journal of Immunology.

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.

Vascular endothelial cells produce, transport and deposit either their own chemokines or chemokines produced by the underlying stroma. Endothelial heparan sulfate (HS) was suggested to be a critical scaffold for these chemokine pools, but it is unclear how steep chemokine gradients are sustained between the lumenal and ablumenal aspects of blood vessels. Addressing this question by semi-quantitative immunostaining of HS moieties around blood vessels with a pan anti-HS IgM mAb, we found a striking HS enrichment in the basal lamina of resting and inflamed post capillary skin venules, as well as in high endothelial venules (HEVs) of lymph nodes. Staining of skin vessels with a glycocalyx probe further suggested that their lumenal glycocalyx contains much lower HS density than their basolateral extracellular matrix (ECM). This polarized HS pattern was observed also in isolated resting and inflamed microvascular dermal cells. Notably, progressive skin inflammation resulted in massive ECM deposition and in further HS enrichment around skin post capillary venules and their associated pericytes. Inflammation-dependent HS enrichment was not compromised in mice deficient in the main HS degrading enzyme, heparanase. Our results suggest that the blood vasculature patterns steep gradients of HS scaffolds between their lumenal and basolateral endothelial aspects, and that inflammatory processes can further enrich the HS content nearby inflamed vessels. We propose that chemokine gradients between the lumenal and ablumenal sides of vessels could be favored by these sharp HS scaffold gradients."}],"issue":"1","publication":"PLoS One","citation":{"mla":"Stoler Barak, Liat, et al. “Blood Vessels Pattern Heparan Sulfate Gradients between Their Apical and Basolateral Aspects.” PLoS One, vol. 9, no. 1, e85699, Public Library of Science, 2014, doi:10.1371/journal.pone.0085699.","short":"L.

MiRNAs associate with members of the Argonaute protein family and bind to partially complementary sequences on mRNAs and induce translational repression or mRNA decay. Using deep sequencing and Northern blotting, we characterized miRNA expression in wild type and miR-155-deficient dendritic cells (DCs) and macrophages. Analysis of different stimuli (LPS, LDL, eLDL, oxLDL) reveals a direct influence of miR-155 on the expression levels of other miRNAs. For example, miR-455 is negatively regulated in miR-155-deficient cells possibly due to inhibition of the transcription factor C/EBPbeta by miR-155. Based on our comprehensive data sets, we propose a model of hierarchical miRNA expression dominated by miR-155 in DCs and macrophages.","lang":"eng"}],"publist_id":"4714","issue":"4"},{"type":"journal_article","issue":"5","publist_id":"3969","intvolume":" 38","department":[{"_id":"MiSi"}],"publisher":"Cell Press","publication_status":"published","status":"public","title":"A conduit to amplify innate immunity","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"2830","year":"2013","oa_version":"None","volume":38,"date_created":"2018-12-11T11:59:49Z","date_updated":"2021-01-12T07:00:01Z","author":[{"id":"3356F664-F248-11E8-B48F-1D18A9856A87","last_name":"Moussion","first_name":"Christine","full_name":"Moussion, Christine"},{"full_name":"Sixt, Michael K","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179","first_name":"Michael K","last_name":"Sixt"}],"scopus_import":1,"month":"05","day":"23","page":"853 - 854","quality_controlled":"1","citation":{"chicago":"Moussion, Christine, and Michael K Sixt. “A Conduit to Amplify Innate Immunity.” Immunity.
