WebJul 28, 1995 · CD5 is a transmembrane protein that is expressed on the surface of T cells and a subset of B cells. The absence of CD5 rendered thymocytes hyperresponsive to stimulation through the T cell antigen receptor (TCR) in vitro. Selection of T cells expressing three distinct transgenic TCRs was also abnormal in CD5-deficient mice.

WebMay 31, 2024 · CD5 is a co-receptor that plays an important role in regulating T cell signaling and fate during thymocyte education. CD5 surface expression on mature single positive thymocytes correlates with the TCR signal strength for positive selecting self-ligands. CD5 also plays a role in T cell function after thymic development is complete. WebApr 22, 2024 · T cells with relatively high self-reactivity (CD5 high) expand more rapidly upon priming and exhibit greater sensitivity to cytokines ( Fulton et al., 2015; Persaud et al., 2014; Weber et al., 2012; Gascoigne and Palmer, 2011 ), whereas T cells with relatively low self-reactivity (CD5 low) survive better in the absence of cytokines and exhibit …
