The genetic absence of Syk or its pharmacologic inhibition using piceatannol abrogated the proper localization of mAbp1 at the phagocytic cup.

Moreover, the genetic absence of mAbp1 almost completely abrogated firm neutrophil adhesion under physiologic shear stress conditions in vitro as well as leukocyte adhesion and extravasation in inflamed cremaster muscle venules of mice treated with tumor-necrosis factor alpha. Functional analysis showed that the down-regulation of mAbp1 diminished the number of beta(2) integrin clusters in the high-affinity conformation under flow conditions.

Long-term application of the sphingosine-1 phosphate receptor agonist FTY720 exerts pleiotropic anti-inflammatory effects, whereas short-term FTY720 boosts antiviral immunity. In this study, we provide evidence that FTY720 potently inhibits Treg proliferation in vitro and in vivo without affecting their viability, phenotype, or in vitro immunosuppression. In contrast, adoptively transferred Treg exposed ex vivo to FTY720 lost their protective effects in murine models of acute glomerulonephritis and acute graft-vs-host disease. On a cellular level, FTY720 inhibits IL-2-induced STAT-5 phosphorylation, paralleled by a loss of FoxP3 expression during Treg expansion in vitro. Notably, loss of in vivo immunosuppression is not due to impaired migration to or localization within secondary lymphoid organs. We could even show a selective trapping of adoptively transferred Treg in inflammatory lymph nodes by FTY720. Finally, Treg isolated from animals systemically exposed to FTY720 also exhibit a significantly impaired proliferative response upon restimulation when compared with Treg isolated from solvent-treated animals. In summary, our data suggest that sphingosine-1 phosphate receptor-mediated signals induced by FTY720 abrogate their in vivo immunosuppressive potential by blocking IL-2 induced expansion, which is indispensable for their in vivo immunosuppressive activity.","lang":"eng"}],"day":"15","extern":1,"year":"2009","author":[{"first_name":"Anna","last_name":"Wolf","full_name":"Wolf, Anna Maria"},{"first_name":"Kathrin","last_name":"Eller","full_name":"Eller, Kathrin"},{"full_name":"Zeiser, Robert","first_name":"Robert","last_name":"Zeiser"},{"full_name":"Dürr, Christoph","first_name":"Christoph","last_name":"Dürr"},{"full_name":"Gerlach, Ulrike V","first_name":"Ulrike","last_name":"Gerlach"},{"first_name":"Michael K","orcid":"0000-0002-6620-9179","last_name":"Sixt","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","full_name":"Michael Sixt"},{"full_name":"Markut, Lydia","first_name":"Lydia","last_name":"Markut"},{"full_name":"Gastl, Guenther","last_name":"Gastl","first_name":"Guenther"},{"first_name":"Alexander","last_name":"Rosenkranz","full_name":"Rosenkranz, Alexander R"},{"full_name":"Wolf, Dominik","first_name":"Dominik","last_name":"Wolf"}],"_id":"3953"},{"publist_id":"2173","citation":{"apa":"Renkawitz, J., Schumann, K., Weber, M., Lämmermann, T., Pflicke, H., Piel, M., … Sixt, M.

Pushing filaments can only cause the membrane to protrude if the expanding actin network experiences a retrograde counter-force, which is usually provided by transmembrane receptors of the integrin family. Here we show that chemotactic dendritic cells mechanically adapt to the adhesive properties of their substrate by switching between integrin-mediated and integrin-independent locomotion. We found that on engaging the integrin-actin clutch, actin polymerization was entirely turned into protrusion, whereas on disengagement actin underwent slippage and retrograde flow. Remarkably, accelerated retrograde flow was balanced by an increased actin polymerization rate; therefore, cell shape and protrusion velocity remained constant on alternating substrates. Due to this adaptive response in polymerization dynamics, tracks of adhesive substrate did not dictate the path of the cells. Instead, directional guidance was exclusively provided by a soluble gradient of chemoattractant, which endowed these 'amoeboid' cells with extraordinary flexibility, enabling them to traverse almost every type of tissue.","lang":"eng"}],"date_updated":"2021-01-12T07:53:27Z","extern":"1","year":"2009","day":"15","author":[{"full_name":"Renkawitz, Jörg","orcid":"0000-0003-2856-3369","first_name":"Jörg","id":"3F0587C8-F248-11E8-B48F-1D18A9856A87","last_name":"Renkawitz"},{"full_name":"Schumann, Kathrin","first_name":"Kathrin","id":"F44D762E-4F9D-11E9-B64C-9EB26CEFFB5F","last_name":"Schumann"},{"full_name":"Weber, Michele","first_name":"Michele","id":"3A3FC708-F248-11E8-B48F-1D18A9856A87","last_name":"Weber"},{"full_name":"Lämmermann, Tim","first_name":"Tim","last_name":"Lämmermann"},{"last_name":"Pflicke","first_name":"Holger","full_name":"Pflicke, Holger"},{"last_name":"Piel","first_name":"Matthieu","full_name":"Piel, Matthieu"},{"full_name":"Polleux, Julien","last_name":"Polleux","first_name":"Julien"},{"last_name":"Spatz","first_name":"Joachim","full_name":"Spatz, Joachim"},{"full_name":"Sixt, Michael K","first_name":"Michael K","orcid":"0000-0002-6620-9179","id":"41E9FBEA-F248-11E8-B48F-1D18A9856A87","last_name":"Sixt"}],"_id":"3954"},{"type":"journal_article","date_published":"2009-12-07T00:00:00Z","doi":"10.1084/jem.20091739","publication_status":"published","publication":"The Journal of Experimental Medicine","page":"2925 - 2935","date_created":"2018-12-11T12:06:05Z","intvolume":"       206","volume":206,"citation":{"mla":"Pflicke, Holger, and Michael K.

In contrast to a common assumption-that intra- and extravasation follow similar molecular principles-we previously showed that lymphatic entry of dendritic cells (DCs) does not require integrin-mediated adhesive interactions. In this study, we demonstrate that DC-entry is also independent of pericellular proteolysis, raising the question of whether lymphatic vessels offer preexisting entry routes. We find that the perilymphatic basement membrane of initial lymphatic vessels is discontinuous and therefore leaves gaps for entering cells. Using a newly developed in situ live cell imaging approach that allows us to dynamically visualize the cells and their extracellular environment, we demonstrate that DCs enter through these discontinuities, which are transiently mechanically dilated by the passaging cells. We further show that penetration of the underlying lymphatic endothelial layer occurs through flap valves lacking continuous intercellular junctions.

Here we extend previous analyses with a static optimum to allow the environment to vary in time as well as in space. The model follows both population dynamics and the trait mean under stabilizing selection, and the outcomes can be understood by comparing the loads due to genetic variance, dispersal, and temporal change. With fixed genetic variance, we obtain two regimes: (1) adaptation that is uniform along the environmental gradient and that responds to the moving optimum as expected for panmictic populations and when the spatial gradient is sufficiently steep, and (2) a population with limited range that adapts more slowly than the environmental optimum changes in both time and space; the population therefore becomes locally extinct and migrates toward suitable habitat. We also use a population‐genetic model with many loci to allow genetic variance to evolve, and we show that the only solution now has uniform adaptation.","lang":"eng"}],"issue":"5","date_updated":"2021-01-12T07:54:46Z","related_material":{"link":[{"url":"https://doi.org/10.1086/659642","relation":"erratum"}]},"volume":174,"quality_controlled":"1","external_id":{"pmid":[" 19788353"]},"article_processing_charge":"No","pubrep_id":"552","article_type":"original","publist_id":"1986","department":[{"_id":"NiBa"}],"language":[{"iso":"eng"}],"type":"journal_article","publication":"American Naturalist","page":"E186 - E204","date_created":"2018-12-11T12:07:09Z","title":"Species' range: Adaptation in space and time","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"University of Chicago Press","author":[{"last_name":"Polechova","id":"3BBFB084-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0003-0951-3112","first_name":"Jitka","full_name":"Polechova, Jitka"},{"full_name":"Barton, Nicholas H","last_name":"Barton","id":"4880FE40-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-8548-5240","first_name":"Nicholas H"},{"last_name":"Marion","first_name":"Glenn","full_name":"Marion, Glenn"}],"day":"05","pmid":1},{"language":[{"iso":"eng"}],"date_published":"2009-05-20T00:00:00Z","type":"journal_article","oa_version":"None","page":"811 - 818","date_created":"2018-12-11T12:07:12Z","publication":"Traffic","publication_status":"published","doi":"10.1111/j.1600-0854.2009.00929.x","citation":{"ista":"Ulrich F, Heisenberg C-PJ. 2009.

Here, we discuss some of the basic concepts about the function of endocytic trafficking during cell migration: transport of integrins from the cell rear to the leading edge in fibroblasts; confinement of signalling to the front of single cells by endocytic transport of growth factors; regulation of movement coherence in multicellular sheets by cadherin turnover; and shaping of extracellular chemokine gradients.

One of the factors thought to be crucial for this process is the extracellular matrix (ECM), which provides positional information for cells and directs polarity specification and epithelial cyst formation in 3D culture. However, in vivo evidence for the role of the ECM in epithelial tissue polarisation is scarce.\r\n\r\nTo gain insight in the factors involved in establishing cell polarity during organogenesis, we are studying a group of epithelial cells called the Dorsal Forerunner Cells (DFCs) in zebrafish embryos. These cells migrate as a cluster towards the vegetal pole of the developing embryo, where they involute. During this process they polarise, and make foci that open up to form a ciliated lumen called Kupffer’s vesicle.\r\n\r\nWe find that interfering with the deposition of components of the extracellular matrix, or with the intracellular anchors of the cells to the matrix, impairs the polarisation of the DFC’s and leads to subsequent defects in lumen formation. In addition, we have developed a method to culture the DFCs ex vivo, allowing us to precisely manipulate the extracellular environment. The possibility of combining the genetic study of Kupffer’s vesicle formation in the live embryo with cell biological techniques in organ culture make this system uniquely relevant for studying the role of the ECM in polarisation during organogenesis.\r\n"}],"month":"08","title":"The role of the extracellular matrix in Kupffer's vesicle formation in zebrafish","status":"public","publisher":"Elsevier","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"status":"public","publisher":"Cell Press","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","title":"Biology and physics of cell shape changes in development","month":"09","date_updated":"2021-01-12T07:54:56Z","issue":"17","abstract":[{"text":"Together with cell growth, division and death, changes in cell shape are of central importance for tissue morphogenesis during development.

In this review, we first discuss the biological and physical mechanisms of cell shape control. We next examine a number of develop mental processes in which cell shape change - either individually or in a coordinated manner - drives embryonic morphogenesis and discuss how cell shape is controlled in these processes.

In zebrafish, the Kupffer’s vesicle (KV) and parapineal (PP) are embryonic struc- tures that share mechanisms of organogenesis and whose func- tion is essential for normal patterning along the left–right axis. Early morphogenesis of KV and PP organs involve the compaction of progenitor cells into a tight cluster within which three-dimen- sional cellular rosettes are formed. Organisation into rosettes pre- cedes the detachment of progenitor cells from neighbouring tissue and thus represents a key step towards organ formation. Such morphogenetic event is essential for organ function and its disruption has profound effects on left–right patterning.","lang":"eng"}],"issue":"Supplement 1","date_updated":"2021-01-12T07:54:57Z","_id":"4160","author":[{"full_name":"Oteíza, Pablo","last_name":"Oteíza","first_name":"Pablo"},{"last_name":"Lemus","first_name":"Carmen","full_name":"Lemus, Carmen"},{"full_name":"Köppen, Mathias","last_name":"Köppen","first_name":"Mathias"},{"full_name":"Palma, Karina","last_name":"Palma","first_name":"Karina"},{"full_name":"Krieg, Michael","last_name":"Krieg","first_name":"Michael"},{"first_name":"Cristina","last_name":"Melo","full_name":"Melo, Cristina"},{"last_name":"Farias","first_name":"Cecilia","full_name":"Farias, Cecilia"},{"first_name":"Eduardo","last_name":"Pulgar","full_name":"Pulgar, Eduardo"},{"first_name":"Steffen","last_name":"Preibisch","full_name":"Preibisch, Steffen"},{"last_name":"Hartel","first_name":"Steffen","full_name":"Hartel, Steffen"},{"first_name":"Carl-Philipp J","orcid":"0000-0002-0912-4566","id":"39427864-F248-11E8-B48F-1D18A9856A87","last_name":"Heisenberg","full_name":"Heisenberg, Carl-Philipp J"},{"first_name":"Miguel","last_name":"Concha","full_name":"Concha, Miguel"}]},{"intvolume":"       126","citation":{"chicago":"Oteíza, Pablo, Mathias Köppen, Michael Krieg, Steffen Preibisch, Steffen Haertel, Daniel Müller, Carl-Philipp J Heisenberg, and Miguel Concha. “Wnt11/Pk1a-Mediated Planar Cell Polarity Signalling Orchestrates Epithelial Organ Morphogenesis by Regulating N-Cadherin Dependent Cell Adhesion Forces.” <i>Mechanisms of Development</i>.

One of these movements is convergence and extension (CE), which is regulated by a non-canonical Wnt/planar cell polarity (PCP) pathway. From our forward genetic screen, we have identified 3-hydroxy-3-methyglutaryl-coenzyme A reductase 1b (hmgcr1b) gene as a dominant enhancer of the silberblick (slb)/wnt11 CE phenotype. hmgcr1b mutant embryos exhibit only very mild CE phenotype during gastrulation while showing a thicker yolk extension at pharyngula stages. Notably, abrogation of hmgcr1b also enhances the CE defects of other core PCP mutants/morphants. The prenylation pathway is one of branches downstream of HMGCR, and has been implicated for lipid modification at the C-terminus of proteins. To test the possibility that the prenylation pathway regulates activities of the PCP pathway, we abrogated farnesyl transferase (FT) or geranylgeranyl transferase (GGT) function using morpholinos on PCP mutant/morphant backgrounds. Consistent with the notion that FT preferentially performs lipid modification on to proteins with the CAAX motif including the core PCP protein Prickle (Pk), abrogation of FT, but not GGT, enhances the pk1a or pk1b morphant CE phenotype, suggesting the specif icity for targets of the prenylation enzymes.\r\n","lang":"eng"}],"issue":"Supplement 1","date_updated":"2021-01-12T07:55:11Z","_id":"4192","author":[{"full_name":"Kai, Masatake","first_name":"Masatake","last_name":"Kai"},{"full_name":"Buchan, Nina","first_name":"Nina","last_name":"Buchan"},{"full_name":"Heisenberg, Carl-Philipp J","last_name":"Heisenberg","id":"39427864-F248-11E8-B48F-1D18A9856A87","first_name":"Carl-Philipp J","orcid":"0000-0002-0912-4566"},{"first_name":"Masazumi","last_name":"Tada","full_name":"Tada, Masazumi"}],"title":"Regulation of planar cell polarity signalling by the prenylation pathway","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","status":"public","publisher":"Elsevier","month":"08","publication":"Mechanisms of Development","date_created":"2018-12-11T12:07:30Z","page":"S132 - S132","doi":"10.1016/j.mod.2009.06.269","publication_status":"published","date_published":"2009-08-05T00:00:00Z","language":[{"iso":"eng"}],"oa_version":"None","type":"journal_article","article_processing_charge":"No","publist_id":"1927","citation":{"ama":"Kai M, Buchan N, Heisenberg C-PJ, Tada M.

Recent studies have provided novel insights into how different tissues function cooperatively in this process. Specifically, they demonstrate a critical function of the epidermis surrounding the hole in modulating the behavior of the amnioserosa cells inside. These findings shed light not only on the mechanisms by which the behavior of different tissues is coordinated during DC, but also on the general mechanisms by which tissues interact to trigger global morphogenesis, an essential but yet poorly explored aspect of embryogenesis.","lang":"eng"}],"_id":"4206","author":[{"orcid":"0000-0002-0912-4566","first_name":"Carl-Philipp J","last_name":"Heisenberg","id":"39427864-F248-11E8-B48F-1D18A9856A87","full_name":"Heisenberg, Carl-Philipp J"}]},{"publication":"Development","date_created":"2018-12-11T12:07:39Z","page":"1305 - 1315","doi":"10.1242/dev.026922","publication_status":"published","date_published":"2009-04-15T00:00:00Z","language":[{"iso":"eng"}],"oa_version":"None","type":"journal_article","article_processing_charge":"No","publist_id":"1901","citation":{"short":"L.

Although the intracellular transport mechanisms underlying nuclear movements have been studied in detail, relatively little is known about signals from surrounding cells and tissues controlling these movements. Here, we show that, in gastrulating zebrafish embryos, convergence movements of nuclei within the yolk syncytial layer (YSL) are guided by mesoderm and endoderm progenitors migrating along the surface of the yolk towards the dorsal side of the developing gastrula. Progenitor cells direct the convergence movements of internal yolk syncytial nuclei (iYSN) by modulating cortical flow within the YSL in which the iYSN are entrained. The effect of mesoderm and endoderm progenitors on the convergence movement of iYSN depends on the expression of E-cadherin, indicating that adhesive contact between the cells and the YSL is required for the mesendoderm-modulated YSL cortical flow mediating nuclear convergence. In summary, our data reveal a crucial function for cortical flow in the coordination of syncytial nuclear movements with surrounding cells and tissues during zebrafish gastrulation.","lang":"eng"}],"issue":"8","date_updated":"2021-01-12T07:55:22Z","_id":"4217","author":[{"last_name":"Carvalho","first_name":"Lara","full_name":"Carvalho, Lara"},{"last_name":"Stuehmer","first_name":"Jan","full_name":"Stuehmer, Jan"},{"full_name":"Bois, Justin","last_name":"Bois","first_name":"Justin"},{"full_name":"Kalaidzidis, Yannis","last_name":"Kalaidzidis","first_name":"Yannis"},{"full_name":"Lecaudey, Virginie","first_name":"Virginie","last_name":"Lecaudey"},{"first_name":"Carl-Philipp J","orcid":"0000-0002-0912-4566","id":"39427864-F248-11E8-B48F-1D18A9856A87","last_name":"Heisenberg","full_name":"Heisenberg, Carl-Philipp J"}],"title":"Control of convergent yolk syncytial layer nuclear movement in zebrafish","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","publisher":"Company of Biologists","status":"public","month":"04"},{"language":[{"iso":"eng"}],"date_published":"2009-08-18T00:00:00Z","oa_version":"None","type":"journal_article","date_created":"2018-12-11T12:07:41Z","page":"875 - 883","publication":"ACS Chemical Biology","publication_status":"published","doi":"10.1021/cb900151k","intvolume":"         4","volume":4,"citation":{"chicago":"Swoboda, Jonathan, Timothy Meredith, Jennifer Campbell, Stephanie Brown, Takashi Suzuki, Mark Tobias Bollenbach, Amy Malhowski, Roy Kishony, Michael Gilmore, and Suzanne Walker. “Discovery of a Small Molecule That Blocks Wall Teichoic Acid Biosynthesis in Staphylococcus Aureus.” <i>ACS Chemical Biology</i>.

Although these polymers are not required for bacterial viability in vitro, genes in many of the biosynthetic pathways are conditionally essential: they cannot be deleted except in strains incapable of initiating polymer synthesis. We report a cell-based, pathway-specific strategy to screen for small molecule inhibitors of conditionally essential enzymes. The screen identifies molecules that prevent the growth of a wildtype bacterial strain but do not affect the growth of a mutant strain incapable of initiating polymer synthesis. We have applied this approach to discover inhibitors of wall teichoic acid (WTA) biosynthesis in Staphylococcus aureus. WTAs are anionic cell surface polysaccharides required for host colonization that have been suggested as targets for new antimicrobials. We have identified a small molecule, 7-chloro-N,N-diethyl-3-(phenylsulfonyl)-[1,2,3]triazolo[1,5-a]quinolin-5-amine (1835F03), that inhibits the growth of a panel of S. aureus strains (MIC = 1−3 μg mL−1), including clinical methicillin-resistant S. aureus (MRSA) isolates. Using a combination of biochemistry and genetics, we have identified the molecular target as TarG, the transmembrane component of the ABC transporter that exports WTAs to the cell surface. We also show that preventing the completion of WTA biosynthesis once it has been initiated triggers growth arrest. The discovery of 1835F03 validates our chemical genetics strategy for identifying inhibitors of conditionally essential enzymes, and the strategy should be applicable to many other bactoprenol-dependent biosynthetic pathways in the pursuit of novel antibacterials and probes of bacterial stress responses.","lang":"eng"}],"month":"08","title":"Discovery of a Small Molecule that Blocks Wall Teichoic Acid Biosynthesis in Staphylococcus aureus","publisher":"American Chemical Society","status":"public","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"}]
