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.

WebThe binding of a variety of monoclonal antibodies to the CD5 (T, gp67) pan T cell differentiation antigen has been shown to potentiate T cell proliferation. In this paper we show that CD5 monoclonal antibodies cause increased intracellular free calcium concentration ([Ca2+]i) in T cells. An increase in [Ca2+]i occurred within 1 min in indo-1 … WebMature T cells express CD3, CD2, CD5, and CD7. One useful immunophenotypic feature in the diagnosis of T-cell neoplasms is the loss of expression of one of these markers (e.g., the cells of HSTCL typically lack CD5 expression and the cells of ATLL lack CD7 expression).

Compared with TCR / mice and WT mice, CD69 and CD5 up-regulation and up-regulation of TCR or CD3 on cell surface from negative to low levels, events occurring during positive selec-tion, were not inhibited in DGK / / DP thymocytes (Fig. 1 D–F). However, the TCR high population in …
WebMar 7, 2024 · Recently, differences in the strength of tonic TCR interactions with self‐peptide, as read‐out by cell surface levels of CD5, were associated with distinct effector potentials among sorted populations of T cells in mice. However, whether CD5 can also be used to parse functional heterogeneity among human T cells is less clear.
