    Cyclic programmed cell death stimulates hormone signaling and root development in Arabidopsis (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2016-01-23
    Beschreibung: The plant root cap, surrounding the very tip of the growing root, perceives and transmits environmental signals to the inner root tissues. In Arabidopsis thaliana, auxin released by the root cap contributes to the regular spacing of lateral organs along the primary root axis. Here, we show that the periodicity of lateral organ induction is driven by recurrent programmed cell death at the most distal edge of the root cap. We suggest that synchronous bursts of cell death in lateral root cap cells release pulses of auxin to surrounding root tissues, establishing the pattern for lateral root formation. The dynamics of root cap turnover may therefore coordinate primary root growth with root branching in order to optimize the uptake of water and nutrients from the soil.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Xuan, Wei -- Band, Leah R -- Kumpf, Robert P -- Van Damme, Daniel -- Parizot, Boris -- De Rop, Gieljan -- Opdenacker, Davy -- Moller, Barbara K -- Skorzinski, Noemi -- Njo, Maria F -- De Rybel, Bert -- Audenaert, Dominique -- Nowack, Moritz K -- Vanneste, Steffen -- Beeckman, Tom -- Biotechnology and Biological Sciences Research Council/United Kingdom -- New York, N.Y. -- Science. 2016 Jan 22;351(6271):384-7. doi: 10.1126/science.aad2776.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Plant Systems Biology, Vlaams Instituut voor Biotechnologie (VIB), Technologiepark 927, 9052 Ghent, Belgium.

    Phase separation of signaling molecules promotes T cell receptor signal transduction (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2016-04-09
    Beschreibung: Activation of various cell surface receptors triggers the reorganization of downstream signaling molecules into micrometer- or submicrometer-sized clusters. However, the functional consequences of such clustering have been unclear. We biochemically reconstituted a 12-component signaling pathway on model membranes, beginning with T cell receptor (TCR) activation and ending with actin assembly. When TCR phosphorylation was triggered, downstream signaling proteins spontaneously separated into liquid-like clusters that promoted signaling outputs both in vitro and in human Jurkat T cells. Reconstituted clusters were enriched in kinases but excluded phosphatases and enhanced actin filament assembly by recruiting and organizing actin regulators. These results demonstrate that protein phase separation can create a distinct physical and biochemical compartment that facilitates signaling.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Su, Xiaolei -- Ditlev, Jonathon A -- Hui, Enfu -- Xing, Wenmin -- Banjade, Sudeep -- Okrut, Julia -- King, David S -- Taunton, Jack -- Rosen, Michael K -- Vale, Ronald D -- 5-F32-DK101188/DK/NIDDK NIH HHS/ -- F32 DK101188/DK/NIDDK NIH HHS/ -- R01 GM056322/GM/NIGMS NIH HHS/ -- R01-GM56322/GM/NIGMS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Apr 29;352(6285):595-9. doi: 10.1126/science.aad9964.

    Prostaglandin E(2) constrains systemic inflammation through an innate lymphoid cell-IL-22 axis (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2016-03-19
    Beschreibung: Systemic inflammation, which results from the massive release of proinflammatory molecules into the circulatory system, is a major risk factor for severe illness, but the precise mechanisms underlying its control are not fully understood. We observed that prostaglandin E2 (PGE2), through its receptor EP4, is down-regulated in human systemic inflammatory disease. Mice with reduced PGE2 synthesis develop systemic inflammation, associated with translocation of gut bacteria, which can be prevented by treatment with EP4 agonists. Mechanistically, we demonstrate that PGE2-EP4 signaling acts directly on type 3 innate lymphoid cells (ILCs), promoting their homeostasis and driving them to produce interleukin-22 (IL-22). Disruption of the ILC-IL-22 axis impairs PGE2-mediated inhibition of systemic inflammation. Hence, the ILC-IL-22 axis is essential in protecting against gut barrier dysfunction, enabling PGE2-EP4 signaling to impede systemic inflammation.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4841390/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4841390/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Duffin, Rodger -- O'Connor, Richard A -- Crittenden, Siobhan -- Forster, Thorsten -- Yu, Cunjing -- Zheng, Xiaozhong -- Smyth, Danielle -- Robb, Calum T -- Rossi, Fiona -- Skouras, Christos -- Tang, Shaohui -- Richards, James -- Pellicoro, Antonella -- Weller, Richard B -- Breyer, Richard M -- Mole, Damian J -- Iredale, John P -- Anderton, Stephen M -- Narumiya, Shuh -- Maizels, Rick M -- Ghazal, Peter -- Howie, Sarah E -- Rossi, Adriano G -- Yao, Chengcan -- 106122/Wellcome Trust/United Kingdom -- BB/K091121/1/Biotechnology and Biological Sciences Research Council/United Kingdom -- DK37097/DK/NIDDK NIH HHS/ -- Medical Research Council/United Kingdom -- New York, N.Y. -- Science. 2016 Mar 18;351(6279):1333-8. doi: 10.1126/science.aad9903.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Medical Research Council (MRC) Centre for Inflammation Research, Queen's Medical Research Institute, The University of Edinburgh, Edinburgh EH16 4TJ, UK. ; Division of Pathway Medicine, Edinburgh Infectious Diseases, The University of Edinburgh, Edinburgh EH16 4SB, UK. ; Institute for Immunology and Infection Research, The University of Edinburgh, Edinburgh EH9 3JT, UK. ; MRC Centre for Regenerative Medicine, The University of Edinburgh, Edinburgh EH16 4UU, UK. ; Department of Gastroenterology, First Affiliated Hospital of Jinan University, Guangzhou 510630, China. ; Department of Veterans Affairs, Tennessee Valley Health Authority, Nashville, TN 37212, USA.

    Oligodendrocyte precursors migrate along vasculature in the developing nervous system (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2016-01-23
    Beschreibung: Oligodendrocytes myelinate axons in the central nervous system and develop from oligodendrocyte precursor cells (OPCs) that must first migrate extensively during brain and spinal cord development. We show that OPCs require the vasculature as a physical substrate for migration. We observed that OPCs of the embryonic mouse brain and spinal cord, as well as the human cortex, emerge from progenitor domains and associate with the abluminal endothelial surface of nearby blood vessels. Migrating OPCs crawl along and jump between vessels. OPC migration in vivo was disrupted in mice with defective vascular architecture but was normal in mice lacking pericytes. Thus, physical interactions with the vascular endothelium are required for OPC migration. We identify Wnt-Cxcr4 (chemokine receptor 4) signaling in regulation of OPC-endothelial interactions and propose that this signaling coordinates OPC migration with differentiation.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Tsai, Hui-Hsin -- Niu, Jianqin -- Munji, Roeben -- Davalos, Dimitrios -- Chang, Junlei -- Zhang, Haijing -- Tien, An-Chi -- Kuo, Calvin J -- Chan, Jonah R -- Daneman, Richard -- Fancy, Stephen P J -- 1P01 NS083513/NS/NINDS NIH HHS/ -- 1R01NS064517/NS/NINDS NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Jan 22;351(6271):379-84. doi: 10.1126/science.aad3839.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Pediatrics, University of California at San Francisco (UCSF), San Francisco, CA 94158, USA. ; Departments of Pharmacology and Neuroscience, University of California at San Diego (UCSD), San Diego, CA 92093, USA. ; Department of Neurosciences, Lerner Research Institute, Cleveland Clinic Foundation, Cleveland, OH 44195, USA. ; Division of Hematology, Department of Medicine, Stanford University, Stanford, CA 94305, USA. ; Division of Hematology, Department of Medicine, Stanford University, Stanford, CA 94305, USA.

    Spatial colocalization and functional link of purinosomes with mitochondria (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2016-02-26
    Beschreibung: Purine biosynthetic enzymes organize into dynamic cellular bodies called purinosomes. Little is known about the spatiotemporal control of these structures. Using super-resolution microscopy, we demonstrated that purinosomes colocalized with mitochondria, and these results were supported by isolation of purinosome enzymes with mitochondria. Moreover, the number of purinosome-containing cells responded to dysregulation of mitochondrial function and metabolism. To explore the role of intracellular signaling, we performed a kinome screen using a label-free assay and found that mechanistic target of rapamycin (mTOR) influenced purinosome assembly. mTOR inhibition reduced purinosome-mitochondria colocalization and suppressed purinosome formation stimulated by mitochondria dysregulation. Collectively, our data suggest an mTOR-mediated link between purinosomes and mitochondria, and a general means by which mTOR regulates nucleotide metabolism by spatiotemporal control over protein association.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉French, Jarrod B -- Jones, Sara A -- Deng, Huayun -- Pedley, Anthony M -- Kim, Doory -- Chan, Chung Yu -- Hu, Haibei -- Pugh, Raymond J -- Zhao, Hong -- Zhang, Youxin -- Huang, Tony Jun -- Fang, Ye -- Zhuang, Xiaowei -- Benkovic, Stephen J -- 1R33EB019785-01/EB/NIBIB NIH HHS/ -- GM024129/GM/NIGMS NIH HHS/ -- Canadian Institutes of Health Research/Canada -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2016 Feb 12;351(6274):733-7. doi: 10.1126/science.aac6054.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biochemistry and Cell Biology, Department of Chemistry, Stony Brook University, Stony Brook, NY 11794, USA. jarrod.french@stonybrook.edu fangy2@corning.com zhuang@chemistry.harvard.edu sjb1@psu.edu. ; Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA. ; Biochemical Technologies, Science and Technology Division, Corning Incorporated, Corning, NY 14831, USA. ; Department of Chemistry, The Pennsylvania State University, University Park, PA 16802, USA. ; Department of Chemistry and Chemical Biology, Harvard University, Cambridge, MA 02138, USA.

    Tuft cells, taste-chemosensory cells, orchestrate parasite type 2 immunity in the gut (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2016-02-06
    Beschreibung: The intestinal epithelium forms an essential barrier between a host and its microbiota. Protozoa and helminths are members of the gut microbiota of mammals, including humans, yet the many ways that gut epithelial cells orchestrate responses to these eukaryotes remain unclear. Here we show that tuft cells, which are taste-chemosensory epithelial cells, accumulate during parasite colonization and infection. Disruption of chemosensory signaling through the loss of TRMP5 abrogates the expansion of tuft cells, goblet cells, eosinophils, and type 2 innate lymphoid cells during parasite colonization. Tuft cells are the primary source of the parasite-induced cytokine interleukin-25, which indirectly induces tuft cell expansion by promoting interleukin-13 production by innate lymphoid cells. Our results identify intestinal tuft cells as critical sentinels in the gut epithelium that promote type 2 immunity in response to intestinal parasites.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Howitt, Michael R -- Lavoie, Sydney -- Michaud, Monia -- Blum, Arthur M -- Tran, Sara V -- Weinstock, Joel V -- Gallini, Carey Ann -- Redding, Kevin -- Margolskee, Robert F -- Osborne, Lisa C -- Artis, David -- Garrett, Wendy S -- F31DK105653/DK/NIDDK NIH HHS/ -- F32DK098826/DK/NIDDK NIH HHS/ -- R01 CA154426/CA/NCI NIH HHS/ -- R01 GM099531/GM/NIGMS NIH HHS/ -- New York, N.Y. -- Science. 2016 Mar 18;351(6279):1329-33. doi: 10.1126/science.aaf1648.

    CLK2 inhibition ameliorates autistic features associated with SHANK3 deficiency (2016)
    American Association for the Advancement of Science (AAAS)
    Details
    Publikationsdatum: 2016-02-06
    Beschreibung: SH3 and multiple ankyrin repeat domains 3 (SHANK3) haploinsufficiency is causative for the neurological features of Phelan-McDermid syndrome (PMDS), including a high risk of autism spectrum disorder (ASD). We used unbiased, quantitative proteomics to identify changes in the phosphoproteome of Shank3-deficient neurons. Down-regulation of protein kinase B (PKB/Akt)-mammalian target of rapamycin complex 1 (mTORC1) signaling resulted from enhanced phosphorylation and activation of serine/threonine protein phosphatase 2A (PP2A) regulatory subunit, B56beta, due to increased steady-state levels of its kinase, Cdc2-like kinase 2 (CLK2). Pharmacological and genetic activation of Akt or inhibition of CLK2 relieved synaptic deficits in Shank3-deficient and PMDS patient-derived neurons. CLK2 inhibition also restored normal sociability in a Shank3-deficient mouse model. Our study thereby provides a novel mechanistic and potentially therapeutic understanding of deregulated signaling downstream of Shank3 deficiency.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bidinosti, Michael -- Botta, Paolo -- Kruttner, Sebastian -- Proenca, Catia C -- Stoehr, Natacha -- Bernhard, Mario -- Fruh, Isabelle -- Mueller, Matthias -- Bonenfant, Debora -- Voshol, Hans -- Carbone, Walter -- Neal, Sarah J -- McTighe, Stephanie M -- Roma, Guglielmo -- Dolmetsch, Ricardo E -- Porter, Jeffrey A -- Caroni, Pico -- Bouwmeester, Tewis -- Luthi, Andreas -- Galimberti, Ivan -- New York, N.Y. -- Science. 2016 Mar 11;351(6278):1199-203. doi: 10.1126/science.aad5487.
