CD5 includes a scavenger receptor cysteine-rich protein domain. T cells express higher levels of CD5 than B cells. CD5 is upregulated on T cells upon strong activation. In the thymus, there is a correlation with CD5 expression and strength of the interaction of the T cell towards self-peptides.
Lymphocyte Activation Gene 3 (LAG3), an inhibitory (checkpoint) receptor on immune system T-cells. LAG3 is the target of early-stage drugs for cancer and autoimmune disorders; IMP321 is a soluble version of LAG3, developed by Prima, while BMS-986016 (from Bristol Myers) and GSK2831781 (Glaxo) are anti-LAG3 monoclonal antibodies.
CD5-CD72 is thought to mediate B cell-B cell interaction. What differentiates B1 cells from other B cells is the variable existence of CD5, CD86, IgM and IgD. [1] B-1 B cells, in the mouse, can be further subdivided into B-1a (CD5 +) and B-1b (CD5 −) subtypes. Unlike B-1a B cells, the B-1b subtype can be generated from precursors in the adult ...
In summary, activation of T cells first requires activation through the non-classical pathway to increase expression of VDR and PLC-γ1 before activation through the classical pathway can proceed. This provides a delayed response mechanism where the innate immune system is allowed time (~48 hrs) to clear an infection before the inflammatory T ...
CD3 (cluster of differentiation 3) is a protein complex and T cell co-receptor that is involved in activating both the cytotoxic T cell (CD8+ naive T cells) and T helper cells (CD4+ naive T cells). [1]

Regulatory B cells (Bregs or B reg cells) represent a small population of B cells that participates in immunomodulation and in the suppression of immune responses. The population of Bregs can be further separated into different human or murine subsets such as B10 cells, marginal zone B cells, Br1 cells, GrB + B cells, CD9 + B cells, and even some plasmablasts or plasma cells.
