    • CD160Ig Fusion Protein Targets a Novel Costimulatory Pathway and Prolongs Allograft Survival 

      D’Addio, Francesca; Ueno, Takuya; Clarkson, Michael; Zhu, Baogong; Vergani, Andrea; Freeman, Gordon James; Sayegh, Mohamed Hassan; Ansari, Mohammed Javeed I.; Fiorina, Paolo; Habicht, Antje (Public Library of Science, 2013)
      CD160 is a cell surface molecule expressed by most NK cells and approximately 50% of CD8+ cytotoxic T lymphocytes. Engagement of CD160 by MHC class-I directly triggers a costimulatory signal to TCR-induced proliferation, ...
    • CD1a autoreactive T cells recognize natural skin oils that function as headless antigens 

      de Jong, Annemieke; Cheng, Tan-Yun; Huang, Shouxiong; Gras, Stephanie; Birkinshaw, Richard W.; Kasmar, Anne; van Rhijn, Ildiko; Peña-Cruz, Victor; Ruan, Daniel T.; Altman, John D.; Rossjohn, Jamie; Moody, D. Branch (2014)
      CD1a autoreactive T cells are common in human blood and skin, but the search for natural autoantigens has been confounded by background T cell responses to CD1 proteins and self lipids. After capturing CD1a-lipid complexes, ...

      The CD200R1:CD200 axis is traditionally considered to limit tissue inflammation by down-regulating pro-inflammatory signaling in myeloid cells bearing the receptor. We generated CD200R1−/− mice and employed them to explore ...
    • CD28 Costimulation Regulates Genome-Wide Effects on Alternative Splicing 

      Butte, Manish J.; Lee, Sun Jung; Jesneck, Jonathan Lee; Keir, Mary E.; Haining, William Nicholas; Sharpe, Arlene Helen (Public Library of Science, 2012)
      CD28 is the major costimulatory receptor required for activation of naïve T cells, yet CD28 costimulation affects the expression level of surprisingly few genes over those altered by TCR stimulation alone. Alternate splicing ...

      CD39 (ENTPD1) is expressed by subsets of pathogenic human CD4+ T cells, such as T helper type 17 (Th17) cells. These Th17 cells are considered important in intestinal inflammation, such as seen in Crohn’s disease. Recently, ...
    • CD39 and Control of Cellular Immune Responses 

      Dwyer, Karen M.; Deaglio, Silvia; Gao, Wenda; Friedman, David J.; Strom, Terry Barton; Robson, Simon Christopher (Springer Verlag, 2007)
      CD39 is the cell surface-located prototypic member of the ecto-nucleoside triphosphate diphosphohydrolase (E-NTPDase) family. Biological actions of CD39 are a consequence (at least in part) of the regulated phosphohydrolytic ...
