    • T Cell Receptor Internalization from the Immunological Synapse Is Mediated by TC21 and RhoG GTPase-Dependent Phagocytosis 

      Cemerski, Saso; Delgado, Pilar; Turner, Martin; Heuser, John; Irvine, Darrell J.; e.a. (Elsevier, 2011-08)
      The immunological synapse (IS) serves a dual role for sustained T cell receptor (TCR) signaling and for TCR downregulation. TC21 (Rras2) is a RRas subfamily GTPase that constitutively associates with the TCR and is implicated ...

      We have studied the energy dependence of the reaction mechanism of the T(t,2n)[superscript 4] He reaction at stellar energies and of its charge symmetric analog reaction [superscript 3]He([superscript 3]He,2p)[superscript ...
    • T-cell death following immune activation is mediated by mitochondria-localized SARM 

      Panneerselvam, P.; Singh, L. P.; Selvarajan, V.; Chng, W. J.; Ng, S. B.; e.a. (Nature Publishing Group, 2012-11)
      Following acute-phase infection, activated T cells are terminated to achieve immune homeostasis, failure of which results in lymphoproliferative and autoimmune diseases. We report that sterile α- and heat armadillo-motif ...
    • T-cell receptor-driven lymphomagenesis in mice derived from a reprogrammed T cell 

      Serwold, T.; Hochedlinger, K.; Swindle, J.; Hedgpeth, J.; Weissman, I. L.; e.a. (National Academy of Sciences (U.S.), 2010-11)
      The conversion of mature somatic cells into pluripotent stem cells, both by nuclear transfer and transduction with specific “reprogramming” genes, represents a major advance in regenerative medicine. Pluripotent stem cell ...
    • T-duality constraints on higher derivatives revisited 

      Hohm, Olaf; Zwiebach, Barton (Springer Berlin Heidelberg, 2016-04)
      We ask to what extent are the higher-derivative corrections of string theory constrained by T-duality. The seminal early work by Meissner tests T-duality by reduction to one dimension using a distinguished choice of field ...
    • TABASCO: A single molecule, base-pair resolved gene expression simulator 

      Kosuri, Sriram; Endy, Drew; Kelly, Jason R. (BioMed Central Ltd, 2007-12)
      Background Experimental studies of gene expression have identified some of the individual molecular components and elementary reactions that comprise and control cellular behavior. Given our current understanding of gene ...
    • tableone: An open source Python package for producing summary statistics for research papers 

      Pollard, Tom Joseph; Johnson, Alistair Edward William; Raffa, Jesse D; Mark, Roger G (Oxford University Press (OUP), 2018-05)
      Objectives:In quantitative research, understanding basic parameters of the study population is key for interpre-tation of the results. As a result, it is typical for the first table (“Table 1”) of a research paper to include ...
    • Tabula Rasaforn-Cz silicon-based photovoltaics 

      LaSalvia, Vincenzo; Youssef, Amanda; Jensen, Mallory Ann; Looney, Erin E.; Nemeth, William; e.a. (Wiley, 2018-08)
      High-temperature annealing, known as Tabula Rasa (TR), proves to be an effective method for dissolving oxygen precipitate nuclei in n-Cz silicon and makes this material resistant to temperature-induced and process-induced ...
