CD5 is expressed by all mature T cells, the B-1a subset of mature B cells, and some leukemic B cells. Its expression is increased in regulatory T and B cells (Tregs\/Bregs). Anergic T and B cells also have elevated CD5 expression. Elevated levels of CD5 are also found in many autoimmune disorders (1-3). CD5 is associated with the T cell receptor (TCR) and negatively modulates T cell activation and differentiation. CD5 expression on the tumor infiltrating T lymphocytes is inversely correlated with their antitumor activity (4-6). Recently, it was reported that CD5 directly binds to IL6 and can mediate downstream signaling. CD5+ B cells promote tumor growth in animal models (7). Reagents targeting CD5 have been actively pursued as therapeutic interventions for cancer and other conditions (8,9).\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCD5; CD5 antigen (p56-62); CD5 molecule; epididymis secretory sperm binding protein; LEU1; Lymphocyte antigen T1\/Leu-1; T-cell surface glycoprotein CD5; T1\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H Mk\nSENSITIVITY: Endogenous\nMW (kDa): 65\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46799469772969,"sku":"39300T","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-39300t","provider":"Iright","version":"1.0","type":"link"}
