The model takes the form of a fully nonlinear degenerate parabolic system. An existence analysis is carried out by adapting ideas from the theory of gradient flows.

How a cell surveys and then corrects its own shape is poorly understood. Here, we demonstrate that spatially distinct microtubule dynamics regulate amoeboid cell migration by locally promoting the retraction of protrusions. In migrating dendritic cells, local microtubule depolymerization within protrusions remote from the microtubule organizing center triggers actomyosin contractility controlled by RhoA and its exchange factor Lfc. Depletion of Lfc leads to aberrant myosin localization, thereby causing two effects that rate-limit locomotion: (1) impaired cell edge coordination during path finding and (2) defective adhesion resolution. Compromised shape control is particularly hindering in geometrically complex microenvironments, where it leads to entanglement and ultimately fragmentation of the cell body. We thus demonstrate that microtubules can act as a proprioceptive device: they sense cell shape and control actomyosin retraction to sustain cellular coherence.","lang":"eng"}],"issue":"6","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","_id":"7875","title":"Microtubules control cellular shape and coherence in amoeboid migrating cells","status":"public","ddc":["570"],"intvolume":" 219","file":[{"file_name":"2020_JCellBiol_Kopf.pdf","access_level":"open_access","file_size":7536712,"content_type":"application/pdf","creator":"dernst","relation":"main_file","file_id":"8801","date_updated":"2020-11-24T13:25:13Z","date_created":"2020-11-24T13:25:13Z","checksum":"cb0b9c77842ae1214caade7b77e4d82d","success":1}],"oa_version":"Published Version","scopus_import":"1","day":"01","article_processing_charge":"No","has_accepted_license":"1","publication":"The Journal of Cell Biology","citation":{"short":"A.

However, we find these proteins to act as positive regulators of migration in different murine cell lines. CRISPR/Cas9-mediated loss of Ena/VASP proteins reduced lamellipodial actin assembly and perturbed lamellipodial architecture, as evidenced by changed network geometry as well as reduction of filament length and number that was accompanied by abnormal Arp2/3 complex and heterodimeric capping protein accumulation. Loss of Ena/VASP function also abolished the formation of microspikes normally embedded in lamellipodia, but not of filopodia capable of emanating without lamellipodia. Ena/VASP-deficiency also impaired integrin-mediated adhesion accompanied by reduced traction forces exerted through these structures.

Anucleate platelets form blood-clots during thrombosis, but also play a crucial role in inflammation. While spatio-temporal dynamics of clot formation are well characterized, the cell-biological mechanisms of platelet recruitment to inflammatory micro-environments remain incompletely understood. Here we identify Arp2/3-dependent lamellipodia formation as a prominent morphological feature of immune-responsive platelets. Platelets use lamellipodia to scan for fibrin(ogen) deposited on the inflamed vasculature and to directionally spread, to polarize and to govern haptotactic migration along gradients of the adhesive ligand. Platelet-specific abrogation of Arp2/3 interferes with haptotactic repositioning of platelets to microlesions, thus impairing vascular sealing and provoking inflammatory microbleeding. During infection, haptotaxis promotes capture of bacteria and prevents hematogenic dissemination, rendering platelets gate-keepers of the inflamed microvasculature. Consequently, these findings identify haptotaxis as a key effector function of immune-responsive platelets.","lang":"eng"}],"publication":"Nature Communications","citation":{"short":"L. Nicolai, K.

The dynamic network of cellular microtubules provides the necessary platform to accommodate processes associated with the transition of cells through the individual phases of cytogenesis. Here, we show that the plant hormone cytokinin fine‐tunes the activity of the microtubular cytoskeleton during cell differentiation and counteracts microtubular rearrangements driven by the hormone auxin. The endogenous upward gradient of cytokinin activity along the longitudinal growth axis in Arabidopsis thaliana roots correlates with robust rearrangements of the microtubule cytoskeleton in epidermal cells progressing from the proliferative to the differentiation stage. Controlled increases in cytokinin activity result in premature re‐organization of the microtubule network from transversal to an oblique disposition in cells prior to their differentiation, whereas attenuated hormone perception delays cytoskeleton conversion into a configuration typical for differentiated cells. Intriguingly, cytokinin can interfere with microtubules also in animal cells, such as leukocytes, suggesting that a cytokinin‐sensitive control pathway for the microtubular cytoskeleton may be at least partially conserved between plant and animal cells.","lang":"eng"}],"intvolume":" 39","status":"public","ddc":["580"],"title":"Phytohormone cytokinin guides microtubule dynamics during cell progression from proliferative to differentiated stage","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","_id":"8142","file":[{"file_size":3497156,"content_type":"application/pdf","creator":"dernst","access_level":"open_access","file_name":"2020_EMBO_Montesinos.pdf","checksum":"43d2b36598708e6ab05c69074e191d57","success":1,"date_created":"2020-12-02T09:13:23Z","date_updated":"2020-12-02T09:13:23Z","relation":"main_file","file_id":"8827"}],"oa_version":"Published Version","scopus_import":"1","has_accepted_license":"1","article_processing_charge":"Yes (via OA deal)","day":"01","article_type":"original","citation":{"chicago":"Montesinos López, Juan C, A Abuzeineh, Aglaja Kopf, Alba Juanes Garcia, Krisztina Ötvös, J Petrášek, Michael K Sixt, and Eva Benková. “Phytohormone Cytokinin Guides Microtubule Dynamics during Cell Progression from Proliferative to Differentiated Stage.” The Embo Journal.

While force coupling is usually mediated by transmembrane adhesion receptors, especially those of the integrin family, amoeboid cells such as leukocytes can migrate extremely fast despite very low adhesive forces1. Here we show that leukocytes cannot only migrate under low adhesion but can also transmit forces in the complete absence of transmembrane force coupling. When confined within three-dimensional environments, they use the topographical features of the substrate to propel themselves. Here the retrograde flow of the actin cytoskeleton follows the texture of the substrate, creating retrograde shear forces that are sufficient to drive the cell body forwards. Notably, adhesion-dependent and adhesion-independent migration are not mutually exclusive, but rather are variants of the same principle of coupling retrograde actin flow to the environment and thus can potentially operate interchangeably and simultaneously. As adhesion-free migration is independent of the chemical composition of the environment, it renders cells completely autonomous in their locomotive behaviour.","lang":"eng"}],"type":"journal_article","oa_version":"None","status":"public","title":"Cellular locomotion using environmental topography","intvolume":" 582","_id":"7885","user_id":"4359f0d1-fa6c-11eb-b949-802e58b17ae8","month":"06","publication_identifier":{"eissn":["14764687"],"issn":["00280836"]},"acknowledged_ssus":[{"_id":"Bio"},{"_id":"LifeSc"},{"_id":"M-Shop"}],"language":[{"iso":"eng"}],"doi":"10.1038/s41586-020-2283-z","quality_controlled":"1","isi":1,"project":[{"grant_number":"281556","_id":"25A603A2-B435-11E9-9278-68D0E5697425","call_identifier":"FP7","name":"Cytoskeletal force generation and force transduction of migrating leukocytes"},{"_id":"25FE9508-B435-11E9-9278-68D0E5697425","grant_number":"724373","call_identifier":"H2020","name":"Cellular navigation along spatial gradients"},{"name":"Mechanical adaptation of lamellipodial actin","call_identifier":"FWF","grant_number":"P29911","_id":"26018E70-B435-11E9-9278-68D0E5697425"},{"name":"Mechanical Adaptation of Lamellipodial Actin Networks in Migrating Cells","call_identifier":"H2020","_id":"260AA4E2-B435-11E9-9278-68D0E5697425","grant_number":"747687"}],"external_id":{"isi":["000532688300008"]},"ec_funded":1,"date_updated":"2024-03-28T23:30:24Z","date_created":"2020-05-24T22:01:01Z","volume":582,"author":[{"orcid":"0000-0003-0666-8928","id":"35B76592-F248-11E8-B48F-1D18A9856A87","last_name":"Reversat","first_name":"Anne","full_name":"Reversat, Anne"},{"orcid":"0000-0001-6120-3723","id":"397A88EE-F248-11E8-B48F-1D18A9856A87","last_name":"Gärtner","first_name":"Florian R","full_name":"Gärtner, Florian R"},{"last_name":"Merrin","first_name":"Jack","orcid":"0000-0001-5145-4609","id":"4515C308-F248-11E8-B48F-1D18A9856A87","full_name":"Merrin, Jack"},{"last_name":"Stopp","first_name":"Julian A","id":"489E3F00-F248-11E8-B48F-1D18A9856A87","full_name":"Stopp, Julian A"},{"first_name":"Saren","last_name":"Tasciyan","id":"4323B49C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-1671-393X","full_name":"Tasciyan, Saren"},{"full_name":"Aguilera Servin, Juan L","orcid":"0000-0002-2862-8372","id":"2A67C376-F248-11E8-B48F-1D18A9856A87","last_name":"Aguilera Servin","first_name":"Juan L"},{"full_name":"De Vries, Ingrid","id":"4C7D837E-F248-11E8-B48F-1D18A9856A87","last_name":"De Vries","first_name":"Ingrid"},{"id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9843-3522","first_name":"Robert","last_name":"Hauschild","full_name":"Hauschild, Robert"},{"full_name":"Hons, Miroslav","first_name":"Miroslav","last_name":"Hons","id":"4167FE56-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6625-3348"},{"last_name":"Piel","first_name":"Matthieu","full_name":"Piel, Matthieu"},{"full_name":"Callan-Jones, Andrew","last_name":"Callan-Jones","first_name":"Andrew"},{"full_name":"Voituriez, Raphael","last_name":"Voituriez","first_name":"Raphael"},{"full_name":"Sixt, Michael K","last_name":"Sixt","first_name":"Michael K","orcid":"0000-0002-6620-9179","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87"}],"related_material":{"link":[{"description":"News on IST Homepage","relation":"press_release","url":"https://ist.ac.at/en/news/off-road-mode-enables-mobile-cells-to-move-freely/"}],"record":[{"relation":"dissertation_contains","status":"public","id":"14697"},{"status":"public","relation":"dissertation_contains","id":"12401"}]},"publication_status":"published","publisher":"Springer Nature","department":[{"_id":"NanoFab"},{"_id":"Bio"},{"_id":"MiSi"}],"year":"2020","acknowledgement":"We thank A.

They continuously monitor blood vessel integrity and tightly coordinate vascular trafficking and functions of multiple cell types. In this way platelets act as ‘patrolling officers of the vascular highway’ that help to establish effective immune responses to infections and cancer.

It is also a hallmark of cancer malignancy. Thousands of publications have elucidated detailed molecular and biophysical mechanisms of cultured cells migrating on flat, 2D substrates of glass and plastic. However, much less is known about how cells successfully navigate the complex 3D environments of living tissues. In these more complex, native environments, cells use multiple modes of migration, including mesenchymal, amoeboid, lobopodial and collective, and these are governed by the local extracellular microenvironment, specific modalities of Rho GTPase signalling and non- muscle myosin contractility. Migration through 3D environments is challenging because it requires the cell to squeeze through complex or dense extracellular structures. Doing so requires specific cellular adaptations to mechanical features of the extracellular matrix (ECM) or its remodelling. In addition, besides navigating through diverse ECM environments and overcoming extracellular barriers, cells often interact with neighbouring cells and tissues through physical and signalling interactions. Accordingly, cells need to call on an impressively wide diversity of mechanisms to meet these challenges. This Review examines how cells use both classical and novel mechanisms of locomotion as they traverse challenging 3D matrices and cellular environments. It focuses on principles rather than details of migratory mechanisms and draws comparisons between 1D, 2D and 3D migration."}],"issue":"12","publication":"Nature Reviews Molecular Cell Biology","citation":{"ama":"Yamada K, Sixt MK.

However, recent evidence suggests that the leading edge may be dispensable for migration, raising the question of what actually controls cell directionality. Here, we exploit the embryonic migration of Drosophila macrophages to bridge the different temporal scales of the behaviours controlling motility. This approach reveals that edge fluctuations during random motility are not persistent and are weakly correlated with motion. In contrast, flow of the actin network behind the leading edge is highly persistent. Quantification of actin flow structure during migration reveals a stable organization and asymmetry in the cell-wide flowfield that strongly correlates with cell directionality. This organization is regulated by a gradient of actin network compression and destruction, which is controlled by myosin contraction and cofilin-mediated disassembly. It is this stable actin-flow polarity, which integrates rapid fluctuations of the leading edge, that controls inherent cellular persistence."}],"intvolume":" 21","title":"Persistent and polarized global actin flow is essential for directionality during cell migration","status":"public","_id":"7105","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","oa_version":"Submitted Version","publication_identifier":{"issn":["1465-7392"],"eissn":["1476-4679"]},"month":"11","quality_controlled":"1","isi":1,"external_id":{"isi":["000495888300009"],"pmid":["31685997"]},"oa":1,"main_file_link":[{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7025891","open_access":"1"}],"language":[{"iso":"eng"}],"doi":"10.1038/s41556-019-0411-5","department":[{"_id":"MiSi"}],"publisher":"Springer Nature","publication_status":"published","pmid":1,"year":"2019","volume":21,"date_updated":"2023-09-06T11:08:52Z","date_created":"2019-11-25T08:55:00Z","author":[{"first_name":"Lawrence","last_name":"Yolland","full_name":"Yolland, Lawrence"},{"last_name":"Burki","first_name":"Mubarik","full_name":"Burki, Mubarik"},{"full_name":"Marcotti, Stefania","last_name":"Marcotti","first_name":"Stefania"},{"full_name":"Luchici, Andrei","last_name":"Luchici","first_name":"Andrei"},{"full_name":"Kenny, Fiona N.","last_name":"Kenny","first_name":"Fiona N."},{"last_name":"Davis","first_name":"John Robert","full_name":"Davis, John Robert"},{"full_name":"Serna-Morales, Eduardo","first_name":"Eduardo","last_name":"Serna-Morales"},{"last_name":"Müller","first_name":"Jan","id":"AD07FDB4-0F61-11EA-8158-C4CC64CEAA8D","full_name":"Müller, Jan"},{"full_name":"Sixt, Michael K","first_name":"Michael K","last_name":"Sixt","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179"},{"last_name":"Davidson","first_name":"Andrew","full_name":"Davidson, Andrew"},{"last_name":"Wood","first_name":"Will","full_name":"Wood, Will"},{"last_name":"Schumacher","first_name":"Linus J.","full_name":"Schumacher, Linus J."},{"first_name":"Robert G.","last_name":"Endres","full_name":"Endres, Robert G."},{"first_name":"Mark","last_name":"Miodownik","full_name":"Miodownik, Mark"},{"last_name":"Stramer","first_name":"Brian M.","full_name":"Stramer, Brian M."}]},{"abstract":[{"lang":"eng","text":"β1-integrins mediate cell–matrix interactions and their trafficking is important in the dynamic regulation of cell adhesion, migration and malignant processes, including cancer cell invasion.

Functionally, RAB13 silencing triggers the intracellular accumulation of active β1-integrin, and reduces integrin activity in focal adhesions and cell migration similarly to GGA2 depletion, indicating that both facilitate active β1-integrin recycling to the plasma membrane.

Indeed, dendrite branching enhances the coverage of the neuron's receptive field and modulates the initial processing of incoming stimuli. Complex dendrite patterns are achieved in vivo through a dynamic process of de novo branch formation, branch extension and retraction. The first step towards branch formation is the generation of a dynamic filopodium-like branchlet. The mechanisms underlying the initiation of dendrite branchlets are therefore crucial to the shaping of dendrites. Through in vivo time-lapse imaging of the subcellular localization of actin during the process of branching of Drosophila larva sensory neurons, combined with genetic analysis and electron tomography, we have identified the Actin-related protein (Arp) 2/3 complex as the major actin nucleator involved in the initiation of dendrite branchlet formation, under the control of the activator WAVE and of the small GTPase Rac1. Transient recruitment of an Arp2/3 component marks the site of branchlet initiation in vivo.

Fibroblastic reticular cells (FRCs) are the main stromal cells and form a sponge-like extracellular matrix network, called conduits , which they thems elves enwrap and contract. Lymph, containing s oluble antigens , arrive in lymph nodes via afferent lymphatic vessels that connect to the s ubcaps ular s inus and conduit network. According to the current paradigm, the conduit network dis tributes afferent lymph through lymph nodes and thus provides acces s for immune cells to lymph-borne antigens. An elas tic caps ule s urrounds the organ and confines the immune cells and FRC network. Lymph nodes are completely packed with lymphocytes and lymphocyte numbers directly dictates the size of the organ. Although lymphocytes cons tantly enter and leave the lymph node, its s ize remains remarkedly s table under homeostatic conditions. It is only partly known how the cellularity and s ize of the lymph node is regulated and how the lymph node is able to swell in inflammation. The role of the FRC network in lymph node s welling and trans fer of fluids are inves tigated in this thes is. Furthermore, we s tudied what trafficking routes are us ed by cancer cells in lymph nodes to form distal metastases.We examined the role of a mechanical feedback in regulation of lymph node swelling. Using parallel plate compression and UV-las er cutting experiments we dis s ected the mechanical force dynamics of the whole lymph node, and individually for FRCs and the caps ule. Physical forces generated by packed lymphocytes directly affect the tens ion on the FRC network and capsule, which increases its resistance to swelling. This implies a feedback mechanism between tis s ue pres s ure and ability of lymphocytes to enter the organ. Following inflammation, the lymph node swells ∼10 fold in two weeks . Yet, what is the role for tens ion on the FRC network and caps ule, and how are lymphocytes able to enter in conditions that resist swelling remain open ques tions . We s how that tens ion on the FRC network is important to limit the swelling rate of the organ so that the FRC network can grow in a coordinated fashion. This is illustrated by interfering with FRC contractility, which leads to faster swelling rates and a dis organized FRC network in the inflamed lymph node. Growth of the FRC network in turn is expected to releas e tens ion on thes e s tructures and lowers the res is tance to swelling, thereby allowing more lymphocytes to enter the organ and drive more swelling. Halt of swelling coincides with a thickening of the caps ule, which forms a thick res is tant band around the organ and lowers tens ion on the FRC network to form a new force equilibrium.The FRC and conduit network are further believed to be a privileged s ite of s oluble information within the lymph node, although many details remain uns olved. We s how by 3D ultra-recons truction that FRCs and antigen pres enting cells cover the s urface of conduit s ys tem for more than 99% and we dis cus s the implications for s oluble information exchangeat the conduit level.Finally, there is an ongoing debate in the cancer field whether and how cancer cells in lymph nodes s eed dis tal metas tas es . We s how that cancer cells infus ed into the lymph node can utilize trafficking routes of immune cells and rapidly migrate to blood vessels. Once in the blood circulation, these cells are able to form metastases in distal tissues.","lang":"eng"}],"type":"dissertation","alternative_title":["ISTA Thesis"],"date_published":"2019-10-09T00:00:00Z","citation":{"short":"F.P.

Instead, these cells are able to function autonomously of the molecular composition in a broad range of tissue compartments. By this means, cells of the hematopoietic lineage retain the capacity to disseminate into connective tissue and recirculate between organs, building the foundation for essential processes such as tissue regeneration or immune surveillance. \r\nCells of the immune system, specifically leukocytes, are extraordinarily good at performing this task. These cells are able to flexibly shift their mode of migration between an adhesion-mediated and an adhesion-independent manner, instantaneously accommodating for any changes in molecular composition of the external scaffold. The key component driving directed leukocyte migration is the chemokine receptor 7, which guides the cell along gradients of chemokine ligand. Therefore, the physical destination of migrating leukocytes is purely deterministic, i.e. given by global directional cues such as chemokine gradients. \r\nNevertheless, these cells typically reside in three-dimensional scaffolds of inhomogeneous complexity, raising the question whether cells are able to locally discriminate between multiple optional migration routes. Current literature provides evidence that leukocytes, specifically dendritic cells, do indeed probe their surrounding by virtue of multiple explorative protrusions. However, it remains enigmatic how these cells decide which one is the more favorable route to follow and what are the key players involved in performing this task. Due to the heterogeneous environment of most tissues, and the vast adaptability of migrating leukocytes, at this time it is not clear to what extent leukocytes are able to optimize their migratory strategy by adapting their level of adhesiveness. And, given the fact that leukocyte migration is characterized by branched cell shapes in combination with high migration velocities, it is reasonable to assume that these cells require fine tuned shape maintenance mechanisms that tightly coordinate protrusion and adhesion dynamics in a spatiotemporal manner. \r\nTherefore, this study aimed to elucidate how rapidly migrating leukocytes opt for an ideal migratory path while maintaining a continuous cell shape and balancing adhesive forces to efficiently navigate through complex microenvironments. \r\nThe results of this study unraveled a role for the microtubule cytoskeleton in promoting the decision making process during path finding and for the first time point towards a microtubule-mediated function in cell shape maintenance of highly ramified cells such as dendritic cells. Furthermore, we found that migrating low-adhesive leukocytes are able to instantaneously adapt to increased tensile load by engaging adhesion receptors. This response was only occurring tangential to the substrate while adhesive properties in the vertical direction were not increased. As leukocytes are primed for rapid migration velocities, these results demonstrate that leukocyte integrins are able to confer a high level of traction forces parallel to the cell membrane along the direction of migration without wasting energy in gluing the cell to the substrate. \r\nThus, the data in the here presented thesis provide new insights into the pivotal role of cytoskeletal dynamics and the mechanisms of force transduction during leukocyte migration. \r\nThereby the here presented results help to further define fundamental principles underlying leukocyte migration and open up potential therapeutic avenues of clinical relevance.\r\n"}],"alternative_title":["ISTA

complex three-dimensional microenvironments1,2,3. These spaces are crowded by cells and extracellular matrix, generating mazes with differently sized gaps that are typically smaller than the diameter of the migrating cell4,5. Most mesenchymal and epithelial cells and some—but not all—cancer cells actively generate their migratory path using pericellular tissue proteolysis6. By contrast, amoeboid cells such as leukocytes use non-destructive strategies of locomotion7, raising the question how these extremely fast cells navigate through dense tissues. Here we reveal that leukocytes sample their immediate vicinity for large pore sizes, and are thereby able to choose the path of least resistance. This allows them to circumnavigate local obstacles while effectively following global directional cues such as chemotactic gradients. Pore-size discrimination is facilitated by frontward positioning of the nucleus, which enables the cells to use their bulkiest compartment as a mechanical gauge. Once the nucleus and the closely associated microtubule organizing centre pass the largest pore, cytoplasmic protrusions still lingering in smaller pores are retracted. These retractions are coordinated by dynamic microtubules; when microtubules are disrupted, migrating cells lose coherence and frequently fragment into migratory cytoplasmic pieces. As nuclear positioning in front of the microtubule organizing centre is a typical feature of amoeboid migration, our findings link the fundamental organization of cellular polarity to the strategy of locomotion."}],"type":"journal_article","date_published":"2019-04-25T00:00:00Z","publication":"Nature","citation":{"ista":"Renkawitz J, Kopf A, Stopp JA, de Vries I, Driscoll MK, Merrin J, Hauschild R, Welf ES, Danuser G, Fiolka R, Sixt MK. 2019.
