We study if migration in vivo in such three-dimensionally confined environments requires changes in the mechanical properties of the surrounding cells using embryonic Drosophila melanogaster hemocytes, also called macrophages, as a model. We find that macrophage invasion into the germband through transient separation of the apposing ectoderm and mesoderm requires cell deformations and reductions in apical tension in the ectoderm. Interestingly, the genetic pathway governing these mechanical shifts acts downstream of the only known tumor necrosis factor superfamily member in Drosophila, Eiger, and its receptor, Grindelwald. Eiger-Grindelwald signaling reduces levels of active Myosin in the germband ectodermal cortex through the localization of a Crumbs complex component, Patj (Pals-1-associated tight junction protein). We therefore elucidate a distinct molecular pathway that controls tissue tension and demonstrate the importance of such regulation for invasive migration in vivo.","lang":"eng"}],"status":"public","ec_funded":1,"department":[{"_id":"DaSi"},{"_id":"CaHe"},{"_id":"Bio"},{"_id":"EM-Fac"},{"_id":"MiSi"}],"article_type":"original","publication_status":"published","related_material":{"link":[{"relation":"press_release","description":"News on IST Homepage","url":"https://ist.ac.at/en/news/cells-change-tension-to-make-tissue-barriers-easier-to-get-through/"}]},"title":"Drosophila TNF modulates tissue tension in the embryo to facilitate macrophage invasive migration","oa":1,"month":"05","_id":"308","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1"},{"publisher":"Cell Press","doi":"10.1016/j.devcel.2018.02.009","type":"journal_article","language":[{"iso":"eng"}],"date_published":"2018-02-26T00:00:00Z","oa_version":"Published Version","external_id":{"isi":["000426150700002"],"pmid":["29486189"]},"author":[{"last_name":"Casano","full_name":"Casano, Alessandra M","first_name":"Alessandra M","id":"3DBA3F4E-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6009-6804"},{"id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179","last_name":"Sixt","first_name":"Michael K","full_name":"Sixt, Michael K"}],"publist_id":"7547","issue":"4","publication":"Developmental Cell","date_updated":"2023-09-08T11:42:28Z","year":"2018","date_created":"2018-12-11T11:45:47Z","page":"405 - 406","quality_controlled":"1","isi":1,"volume":44,"article_processing_charge":"No","pmid":1,"main_file_link":[{"open_access":"1","url":"https://www.ncbi.nlm.nih.gov/pubmed/29486189"}],"scopus_import":"1","month":"02","_id":"318","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","publication_status":"published","oa":1,"title":"A fat lot of good for wound healing","acknowledgement":"Short Survey","department":[{"_id":"MiSi"}],"abstract":[{"text":"The insect’s fat body combines metabolic and immunological functions.

Branched actin networks construct lamellipodial protrusions at the leading edge of migrating cells. These are typically seen as adhesive structures, which mediate force transduction to the extracellular matrix that leads to forward locomotion. We ablated Arp2/3 nucleation promoting factor WAVE in DCs and found that the resulting cells lack lamellipodial protrusions. Instead, depending on the maturation state, one or multiple filopodia were formed. By challenging these cells in a variety of migration assays we found that lamellipodial protrusions are dispensable for the locomotion of leukocytes and actually dampen the speed of migration. However, lamellipodia are critically required to negotiate complex environments that DCs experience while they travel to the next draining lymph node. Taken together our results suggest that leukocyte lamellipodia have rather a sensory- than a force transducing function. Furthermore, we show for the first time structure and dynamics of dendritic cell F-actin at the immunological synapse with naïve T cells. Dendritic cell F-actin appears as dynamic foci that are nucleated by the Arp2/3 complex. WAVE ablated dendritic cells show increased membrane tension, leading to an altered ultrastructure of the immunological synapse and severe T cell priming defects. These results point towards a previously unappreciated role of the cellular mechanics of dendritic cells in T cell activation. Additionally, we present a novel cell culture based system for the differentiation of dendritic cells from conditionally immortalized hematopoietic precursors. These precursor cells are genetically tractable via the CRISPR/Cas9 system while they retain their ability to differentiate into highly migratory dendritic cells and other immune cells. This will foster the study of all aspects of dendritic cell biology and beyond.

Although lymph node metastasis in cancer patients correlates with poor prognosis, evidence is lacking as to whether and how tumor cells enter the bloodstream via lymph nodes. To investigate this question, we delivered carcinoma cells into the lymph nodes of mice by microinfusing the cells into afferent lymphatic vessels. We found that tumor cells rapidly infiltrated the lymph node parenchyma, invaded blood vessels, and seeded lung metastases without involvement of the thoracic duct. These results suggest that the lymph node blood vessels can serve as an exit route for systemic dissemination of cancer cells in experimental mouse models. Whether this form of tumor cell spreading occurs in cancer patients remains to be determined.","lang":"eng"}],"status":"public","ec_funded":1,"intvolume":"       359","citation":{"apa":"Brown, M., Assen, F.

To investigate adhesion plasticity, we have selected a stable isogenic subpopulation of human MDA-MB-468 breast carcinoma cells growing in suspension. These suspension cells are unable to re-adhere to various matrices or to contract three-dimensional collagen lattices. By using transcriptome analysis, we identified the focal adhesion protein tensin3 (Tns3) as a determinant of adhesion plasticity. Tns3 is strongly reduced at mRNA and protein levels in suspension cells. Furthermore, by transiently challenging breast cancer cells to grow under non-adherent conditions markedly reduces Tns3 protein expression, which is regained upon re-adhesion. Stable knockdown of Tns3 in parental MDA-MB-468 cells results in defective adhesion, spreading and migration. Tns3-knockdown cells display impaired structure and dynamics of focal adhesion complexes as determined by immunostaining. Restoration of Tns3 protein expression in suspension cells partially rescues adhesion and focal contact composition. Our work identifies Tns3 as a crucial focal adhesion component regulated by, and functionally contributing to, the switch between adhesive and non-adhesive states in MDA-MB-468 cancer cells.","lang":"eng"}],"department":[{"_id":"MiSi"}],"publication_status":"published","oa":1,"title":"A dual phenotype of MDA MB 468 cancer cells reveals mutual regulation of tensin3 and adhesion plasticity","article_type":"original","_id":"694","month":"07","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publication_identifier":{"issn":["00219533"]},"pmid":1,"scopus_import":1,"file":[{"file_name":"2017_CellScience_Vess.pdf","access_level":"open_access","date_updated":"2020-07-14T12:47:45Z","date_created":"2019-10-24T09:43:56Z","file_id":"6966","content_type":"application/pdf","checksum":"42c81a0a4fc3128883b391c3af3f74bc","relation":"main_file","creator":"dernst","file_size":10847596}],"volume":130,"date_created":"2018-12-11T11:47:58Z","year":"2017","quality_controlled":"1","page":"2172 - 2184","date_updated":"2021-01-12T08:09:41Z","publication":"Journal of Cell Science","issue":"13","publist_id":"7008","author":[{"last_name":"Veß","first_name":"Astrid","full_name":"Veß, Astrid"},{"last_name":"Blache","first_name":"Ulrich","full_name":"Blache, Ulrich"},{"last_name":"Leitner","full_name":"Leitner, Laura","first_name":"Laura"},{"first_name":"Angela","full_name":"Kurz, Angela","last_name":"Kurz"},{"first_name":"Anja","full_name":"Ehrenpfordt, Anja","last_name":"Ehrenpfordt"},{"first_name":"Michael K","full_name":"Sixt, Michael K","last_name":"Sixt","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179"},{"first_name":"Guido","full_name":"Posern, Guido","last_name":"Posern"}],"ddc":["570"],"external_id":{"pmid":["28515231"]},"oa_version":"Published Version","date_published":"2017-07-01T00:00:00Z","language":[{"iso":"eng"}],"type":"journal_article","file_date_updated":"2020-07-14T12:47:45Z","doi":"10.1242/jcs.200899","publisher":"Company of Biologists"},{"day":"21","intvolume":"       171","citation":{"ama":"Mueller J, Szep G, Nemethova M, et al.

In vitro reconstitution studies suggest that the structure and the dynamics of actin networks respond to mechanical forces. We demonstrate that lamellipodial actin of migrating cells responds to mechanical load when membrane tension is modulated. In a steady state, migrating cell filaments assume the canonical dendritic geometry, defined by Arp2/3-generated 70° branch points. Increased tension triggers a dense network with a broadened range of angles, whereas decreased tension causes a shift to a sparse configuration dominated by filaments growing perpendicularly to the plasma membrane. We show that these responses emerge from the geometry of branched actin: when load per filament decreases, elongation speed increases and perpendicular filaments gradually outcompete others because they polymerize the shortest distance to the membrane, where they are protected from capping. This network-intrinsic geometrical adaptation mechanism tunes protrusive force in response to mechanical load."}],"department":[{"_id":"MiSi"},{"_id":"Bio"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","month":"09","_id":"727","title":"Load adaptation of lamellipodial actin networks","publication_status":"published","article_processing_charge":"No","publication_identifier":{"issn":["00928674"]},"scopus_import":"1","page":"188 - 200","quality_controlled":"1","date_created":"2018-12-11T11:48:10Z","year":"2017","date_updated":"2023-09-28T11:33:49Z","acknowledged_ssus":[{"_id":"ScienComp"}],"project":[{"_id":"25AD6156-B435-11E9-9278-68D0E5697425","grant_number":"LS13-029","name":"Modeling of Polarization and Motility of Leukocytes in Three-Dimensional Environments"},{"call_identifier":"FP7","_id":"25A603A2-B435-11E9-9278-68D0E5697425","grant_number":"281556","name":"Cytoskeletal force generation and force transduction of migrating leukocytes (EU)"}],"volume":171,"isi":1,"external_id":{"isi":["000411331800020"]},"oa_version":"None","date_published":"2017-09-21T00:00:00Z","issue":"1","publist_id":"6951","publication":"Cell","author":[{"full_name":"Mueller, Jan","first_name":"Jan","last_name":"Mueller"},{"full_name":"Szep, Gregory","first_name":"Gregory","last_name":"Szep","id":"4BFB7762-F248-11E8-B48F-1D18A9856A87"},{"id":"34E27F1C-F248-11E8-B48F-1D18A9856A87","last_name":"Nemethova","first_name":"Maria","full_name":"Nemethova, Maria"},{"last_name":"De Vries","full_name":"De Vries, Ingrid","first_name":"Ingrid","id":"4C7D837E-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Lieber, Arnon","first_name":"Arnon","last_name":"Lieber"},{"last_name":"Winkler","first_name":"Christoph","full_name":"Winkler, Christoph"},{"first_name":"Karsten","full_name":"Kruse, Karsten","last_name":"Kruse"},{"last_name":"Small","first_name":"John","full_name":"Small, John"},{"first_name":"Christian","full_name":"Schmeiser, Christian","last_name":"Schmeiser"},{"last_name":"Keren","full_name":"Keren, Kinneret","first_name":"Kinneret"},{"first_name":"Robert","full_name":"Hauschild, Robert","last_name":"Hauschild","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-9843-3522"},{"full_name":"Sixt, Michael K","first_name":"Michael K","last_name":"Sixt","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179"}],"doi":"10.1016/j.cell.2017.07.051","publisher":"Cell Press","language":[{"iso":"eng"}],"type":"journal_article"},{"author":[{"id":"3B1B77E4-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-1073-744X","last_name":"Leithner","full_name":"Leithner, Alexander F","first_name":"Alexander F"}],"ddc":["570"],"department":[{"_id":"MiSi"}],"date_published":"2017-08-09T00:00:00Z","oa_version":"Published Version","type":"research_data","file_date_updated":"2020-07-14T12:47:04Z","oa":1,"title":"Immunological synapse DC-Tcells","publisher":"Institute of Science and Technology Austria","_id":"5567","doi":"10.15479/AT:ISTA:71","datarep_id":"71","month":"08","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","citation":{"short":"A.F.

We quantified actin filament order in human cells using fluorescence polarization microscopy and found that cleavage furrow ingression initiates by contraction of an equatorial actin network with randomly oriented filaments. The network subsequently gradually reoriented actin filaments along the cell equator. This strictly depended on myosin II activity, suggesting local network reorganization by mechanical forces. Cortical laser microsurgery revealed that during cytokinesis progression, mechanical tension increased substantially along the direction of the cell equator, while the network contracted laterally along the pole-to-pole axis without a detectable increase in tension. Our data suggest that an asymmetric increase in cortical tension promotes filament reorientation along the cytokinetic cleavage furrow, which might have implications for diverse other biological processes involving actomyosin rings."}],"citation":{"ama":"Spira F, Cuylen Haering S, Mehta S, et al.

Despite these versatile tasks in mammalian biology, their skills on a cellular level are deemed limited, mainly consisting in rolling, adhesion, and aggregate formation. Here, we identify an unappreciated asset of platelets and show that adherent platelets use adhesion receptors to mechanically probe the adhesive substrate in their local microenvironment. When actomyosin-dependent traction forces overcome substrate resistance, platelets migrate and pile up the adhesive substrate together with any bound particulate material. They use this ability to act as cellular scavengers, scanning the vascular surface for potential invaders and collecting deposited bacteria. Microbe collection by migrating platelets boosts the activity of professional phagocytes, exacerbating inflammatory tissue injury in sepsis. This assigns platelets a central role in innate immune responses and identifies them as potential targets to dampen inflammatory tissue damage in clinical scenarios of severe systemic infection. In addition to their role in thrombosis and hemostasis, platelets can also migrate to sites of infection to help trap bacteria and clear the vascular surface.","lang":"eng"}],"ec_funded":1,"intvolume":"       171","citation":{"ieee":"F.

The formins FMNL2 and FMNL3 are Cdc42 effectors targeting to the lamellipodium tip and shown here to nucleate and elongate actin filaments with complementary activities in vitro. In migrating B16-F1 melanoma cells, both formins contribute to the velocity of lamellipodium protrusion. Loss of FMNL2/3 function in melanoma cells and fibroblasts reduces lamellipodial width, actin filament density and -bundling, without changing patterns of Arp2/3 complex incorporation. Strikingly, in melanoma cells, FMNL2/3 gene inactivation almost completely abolishes protrusion forces exerted by lamellipodia and modifies their ultrastructural organization. Consistently, CRISPR/Cas-mediated depletion of FMNL2/3 in fibroblasts reduces both migration and capability of cells to move against viscous media. Together, we conclude that force generation in lamellipodia strongly depends on FMNL formin activity, operating in addition to Arp2/3 complex-dependent filament branching.","lang":"eng"}],"article_number":"14832","status":"public","intvolume":"         8","citation":{"mla":"Kage, Frieda, et al. “FMNL Formins Boost Lamellipodial Force Generation.” <i>Nature Communications</i>, vol. 8, 14832, Nature Publishing Group, 2017, doi:<a href=\"https://doi.org/10.1038/ncomms14832\">10.1038/ncomms14832</a>.","ieee":"F.

Using spinning disk confocal microscopy to image filopodial dynamics in mouse resident Lifeact-EGFP macrophages, we show that filopodia, or filopodia-like structures, support pathogen clearance by multiple means. Filopodia supported the phagocytic uptake of bacterial (Escherichia coli) particles by (i) capturing along the filopodial shaft and surfing toward the cell body, the most common mode of capture; (ii) capturing via the tip followed by retraction; (iii) combinations of surfing and retraction; or (iv) sweeping actions. In addition, filopodia supported the uptake of zymosan (Saccharomyces cerevisiae) particles by (i) providing fixation, (ii) capturing at the tip and filopodia-guided actin anterograde flow with phagocytic cup formation, and (iii) the rapid growth of new protrusions. To explore the role of filopodia-inducing Cdc42, we generated myeloid-restricted Cdc42 knock-out mice. Cdc42-deficient macrophages exhibited rapid phagocytic cup kinetics, but reduced particle clearance, which could be explained by the marked rounded-up morphology of these cells. Macrophages lacking Myo10, thought to act downstream of Cdc42, had normal morphology, motility, and phagocytic cup formation, but displayed markedly reduced filopodia formation. In conclusion, live-cell imaging revealed multiple mechanisms involving macrophage filopodia in particle capture and engulfment. Cdc42 is not critical for filopodia or phagocytic cup formation, but plays a key role in driving macrophage lamellipodial spreading.","lang":"eng"}],"status":"public","has_accepted_license":"1","day":"28","intvolume":"       292","citation":{"ista":"Horsthemke M, Bachg A, Groll K, Moyzio S, Müther B, Hemkemeyer S, Wedlich Söldner R, Sixt MK, Tacke S, Bähler M, Hanley P. 2017.

How monolayers cooperate with the penetrating cells to support their transit is poorly understood. We studied dendritic cell (DC) entry into lymphatic capillaries as a model system for transendothelial migration. We find that the chemokine CCL21, which is the decisive guidance cue for intravasation, mainly localizes in the trans-Golgi network and intracellular vesicles of lymphatic endothelial cells. Upon DC transmigration, these Golgi deposits disperse and CCL21 becomes extracellularly enriched at the sites of endothelial cell-cell junctions. When we reconstitute the transmigration process in vitro, we find that secretion of CCL21-positive vesicles is triggered by a DC contact-induced calcium signal, and selective calcium chelation in lymphatic endothelium attenuates transmigration. Altogether, our data demonstrate a chemokine-mediated feedback between DCs and lymphatic endothelium, which facilitates transendothelial migration."}],"status":"public","ec_funded":1,"author":[{"orcid":"0000-0001-7829-3518","id":"368EE576-F248-11E8-B48F-1D18A9856A87","first_name":"Kari","full_name":"Vaahtomeri, Kari","last_name":"Vaahtomeri"},{"first_name":"Markus","full_name":"Brown, Markus","last_name":"Brown","id":"3DAB9AFC-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Hauschild","full_name":"Hauschild, Robert","first_name":"Robert","orcid":"0000-0001-9843-3522","id":"4E01D6B4-F248-11E8-B48F-1D18A9856A87"},{"id":"4C7D837E-F248-11E8-B48F-1D18A9856A87","last_name":"De Vries","first_name":"Ingrid","full_name":"De Vries, Ingrid"},{"id":"3B1B77E4-F248-11E8-B48F-1D18A9856A87","full_name":"Leithner, Alexander F","first_name":"Alexander F","last_name":"Leithner"},{"id":"3C23B994-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8599-1226","first_name":"Matthias","full_name":"Mehling, Matthias","last_name":"Mehling"},{"last_name":"Kaufmann","first_name":"Walter","full_name":"Kaufmann, Walter","orcid":"0000-0001-9735-5315","id":"3F99E422-F248-11E8-B48F-1D18A9856A87"},{"id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-6620-9179","last_name":"Sixt","first_name":"Michael K","full_name":"Sixt, Michael K"}],"ddc":["570"],"publist_id":"7052","publication":"Cell Reports","issue":"5","date_published":"2017-05-02T00:00:00Z","oa_version":"Published Version","type":"journal_article","file_date_updated":"2020-07-14T12:47:38Z","language":[{"iso":"eng"}],"publisher":"Cell Press","doi":"10.1016/j.celrep.2017.04.027","scopus_import":1,"publication_identifier":{"issn":["22111247"]},"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)"},"article_processing_charge":"Yes","file":[{"date_updated":"2020-07-14T12:47:38Z","access_level":"open_access","date_created":"2018-12-12T10:14:54Z","content_type":"application/pdf","file_id":"5109","file_name":"IST-2017-900-v1+1_1-s2.0-S2211124717305211-main.pdf","creator":"system","file_size":2248814,"checksum":"8fdddaab1f1d76a6ec9ca94dcb6b07a2","relation":"main_file"}],"volume":19,"project":[{"call_identifier":"FP7","_id":"25A603A2-B435-11E9-9278-68D0E5697425","name":"Cytoskeletal force generation and force transduction of migrating leukocytes (EU)","grant_number":"281556"},{"grant_number":"Y 564-B12","name":"Cytoskeletal force generation and transduction of leukocytes (FWF)","_id":"25A8E5EA-B435-11E9-9278-68D0E5697425","call_identifier":"FWF"}],"date_updated":"2023-02-23T12:50:09Z","year":"2017","date_created":"2018-12-11T11:47:50Z","page":"902 -

Gradients can either be soluble or immobilized to tissues as demonstrated for the haptotactic migration of dendritic cells (DCs) toward higher concentrations of immobilized chemokine CCL21. To elucidate how gradient characteristics govern cellular response patterns, we here introduce an in vitro system allowing to track migratory responses of DCs to precisely controlled immobilized gradients of CCL21. We find that haptotactic sensing depends on the absolute CCL21 concentration and local steepness of the gradient, consistent with a scenario where DC directionality is governed by the signal-to-noise ratio of CCL21 binding to the receptor CCR7. We find that the conditions for optimal DC guidance are perfectly provided by the CCL21 gradients we measure in vivo. Furthermore, we find that CCR7 signal termination by the G-protein-coupled receptor kinase 6 (GRK6) is crucial for haptotactic but dispensable for chemotactic CCL21 gradient sensing in vitro and confirm those observations in vivo. These findings suggest that stable, tissue-bound CCL21 gradients as sustainable “roads” ensure optimal guidance in vivo."}],"ec_funded":1,"department":[{"_id":"MiSi"},{"_id":"Bio"},{"_id":"NanoFab"}],"publication_status":"published","title":"Dendritic cells interpret haptotactic chemokine gradients in a manner governed by signal to noise ratio and dependent on GRK6","month":"05","_id":"674","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87"},{"file":[{"access_level":"open_access","date_updated":"2020-07-14T12:47:40Z","date_created":"2018-12-12T10:15:48Z","file_id":"5171","content_type":"application/pdf","file_name":"IST-2017-899-v1+1_1-s2.0-S2211124717305454-main.pdf","creator":"system","file_size":3005610,"checksum":"efc7287d9c6354983cb151880e9ad72a","relation":"main_file"}],"volume":19,"date_created":"2018-12-11T11:47:52Z","year":"2017","page":"1294 - 1303","quality_controlled":"1","date_updated":"2021-01-12T08:08:57Z","publication_identifier":{"issn":["22111247"]},"scopus_import":1,"tmp":{"legal_code_url":"https://creativecommons.org/licenses/by-nc-nd/4.0/legalcode","name":"Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International (CC BY-NC-ND 4.0)","image":"/images/cc_by_nc_nd.png","short":"CC BY-NC-ND (4.0)"},"language":[{"iso":"eng"}],"type":"journal_article","file_date_updated":"2020-07-14T12:47:40Z","doi":"10.1016/j.celrep.2017.04.051","publisher":"Cell Press","publication":"Cell Reports","issue":"7","publist_id":"7046","author":[{"last_name":"Lademann","first_name":"Claudio","full_name":"Lademann, Claudio"},{"orcid":"0000-0003-2856-3369","id":"3F0587C8-F248-11E8-B48F-1D18A9856A87","full_name":"Renkawitz, Jörg","first_name":"Jörg","last_name":"Renkawitz"},{"full_name":"Pfander, Boris","first_name":"Boris","last_name":"Pfander"},{"last_name":"Jentsch","full_name":"Jentsch, Stefan","first_name":"Stefan"}],"ddc":["570"],"oa_version":"Published Version","date_published":"2017-05-16T00:00:00Z","status":"public","abstract":[{"lang":"eng","text":"The INO80 complex (INO80-C) is an evolutionarily conserved nucleosome remodeler that acts in transcription, replication, and genome stability.

However, the causes of the HR defect in INO80-C mutant cells are controversial. Here, we unite previous findings using a system to study HR with high spatial resolution in budding yeast. We find that INO80-C has at least two distinct functions during HR—DNA end resection and presynaptic filament formation. Importantly, the second function is linked to the histone variant H2A.Z. In the absence of H2A.Z, presynaptic filament formation and HR are restored in INO80-C-deficient mutants, suggesting that presynaptic filament formation is the crucial INO80-C function during HR."}],"citation":{"short":"C.

Neutrophils are exceptionally short-lived leukocytes, yet it remains unclear whether the lifespan of pathogen-engaged neutrophils is regulated differently from that in the circulating steady-state pool. Here, we have found that under homeostatic conditions, the mRNA-destabilizing protein tristetraprolin (TTP) regulates apoptosis and the numbers of activated infiltrating murine neutrophils but not neutrophil cellularity. Activated TTP-deficient neutrophils exhibited decreased apoptosis and enhanced accumulation at the infection site. In the context of myeloid-specific deletion of Ttp, the potentiation of neutrophil deployment protected mice against lethal soft tissue infection with Streptococcus pyogenes and prevented bacterial dissemination. Neutrophil transcriptome analysis revealed that decreased apoptosis of TTP-deficient neutrophils was specifically associated with elevated expression of myeloid cell leukemia 1 (Mcl1) but not other antiapoptotic B cell leukemia/ lymphoma 2 (Bcl2) family members. Higher Mcl1 expression resulted from stabilization of Mcl1 mRNA in the absence of TTP. The low apoptosis rate of infiltrating TTP-deficient neutrophils was comparable to that of transgenic Mcl1-overexpressing neutrophils. Our study demonstrates that posttranscriptional gene regulation by TTP schedules the termination of the antimicrobial engagement of neutrophils. The balancing role of TTP comes at the cost of an increased risk of bacterial infections.","lang":"eng"}],"day":"01","citation":{"chicago":"Ebner, Florian, Vitaly Sedlyarov, Saren Tasciyan, Masa Ivin, Franz Kratochvill, Nina Gratz, Lukas Kenner, Andreas Villunger, Michael K Sixt, and Pavel Kovarik. “The RNA-Binding Protein Tristetraprolin Schedules Apoptosis of Pathogen-Engaged Neutrophils during Bacterial Infection.” <i>The Journal of Clinical Investigation</i>.

In this regard, prostaglandin E 2 (PGE 2) is mostly considered a myeloid-derived immunosuppressive molecule. We describe for the first time that T cells secrete PGE 2 during T-cell receptor stimulation. In addition, we show that autocrine PGE 2 signaling through EP receptors is essential for optimal CD4 + T-cell activation in vitro and in vivo, and for T helper 1 (Th1) and regulatory T cell differentiation. PGE 2 was found to provide additive co-stimulatory signaling through AKT activation. Intravital multiphoton microscopy showed that triggering EP receptors in T cells is also essential for the stability of T cell-dendritic cell (DC) interactions and Th-cell accumulation in draining lymph nodes (LNs) during inflammation. We further demonstrated that blocking EP receptors in T cells during the initial phase of collagen-induced arthritis in mice resulted in a reduction of clinical arthritis. This could be attributable to defective T-cell activation, accompanied by a decline in activated and interferon-γ-producing CD4 + Th1 cells in draining LNs. In conclusion, we prove that T lymphocytes secret picomolar concentrations of PGE 2, which in turn provide additive co-stimulatory signaling, enabling T cells to attain a favorable activation threshold. PGE 2 signaling in T cells is also required for maintaining long and stable interactions with DCs within LNs. Blockade of EP receptors in vivo impairs T-cell activation and development of T cell-mediated inflammatory responses. This may have implications in various pathophysiological settings.","lang":"eng"}],"day":"01","intvolume":"        94","citation":{"ama":"Sreeramkumar V, Hons M, Punzón C, et al.

Decades of investigations have uncovered many of the molecular and physical mechanisms underlying cell migration. Together with protrusion extension and cell body retraction, adhesion to the substrate via specific focal adhesion points has long been considered an essential step in cell migration. Although this is true for cells moving on two-dimensional substrates, recent studies have demonstrated that focal adhesions are not required for cells moving in three dimensions, in which confinement is sufficient to maintain a cell in contact with its substrate. Here, we review the investigations that have led to challenging the requirement of specific adhesions for migration, discuss the physical mechanisms proposed for cell body translocation during focal adhesion-independent migration, and highlight the remaining open questions for the future."}],"status":"public"}]
