Flow cytometric analysis of human CD5 expression on human peripheral blood leukocytes. Human peripheral blood leukocytes were stained with Brilliant Violet 421™ Mouse Anti-Human CD19 Antibody and either PE Mouse IgG1, κ Isotype Control (left panel) or SDT PE Mouse Anti-Human CD5 Antibody (right panel) at 5 μl/test. Total viable cells, as determined by Fixable Viability Dye 515 (S0D0013), were used for analysis. Flow cytometry and data analysis were performed using Agilent NovoCyte Quanteon and FlowJo™ software.

Background
CD5 is a 67 kDa type I cell surface glycoprotein that belongs to the scavenger receptor cysteine-rich (SRCR) family. It is expressed on all T cells and a subset of B cells known as B-1a cells. CD5 plays a crucial role in regulating T cell receptor (TCR) signaling and acts as a negative regulator of T cell activation. It helps fine-tune the threshold for T cell activation during thymocyte development and suppresses peripheral T cell activation by inhibiting TCR-proximal signaling. In B-1a cells, CD5 helps prevent self-reactivity by dampening B cell receptor (BCR) signals. The expression of CD5 is also associated with cell survival, apoptosis, and the development of regulatory T cells. Additionally, CD5 may be involved in the regulation of dendritic cell function and cytokine production.
