Flow cytometric analysis of CD152 expression on activated human PBMC (human peripheral blood mononuclear cell). PHA-activated (2 days) human PBMC were stained with Brilliant Violet 421™ Mouse Anti-Human CD3 antibody and either Mouse IgG2a, κ Isotype Control or SDT FITC Mouse Anti-Human CD152 Antibody at 5 μl/test. Flow cytometry and data analysis were performed using BD FACSymphony™ A1 and FlowJo™ software

Background
CD152, also known as CTLA-4 (cytotoxic T-lymphocyte-associated protein 4), is a protein receptor that functions as an immune checkpoint. It is a member of the immunoglobulin superfamily and is expressed on the surface of T cells. The CD152 gene consists of 4 exons and encodes a protein with a signal peptide, an Ig-like domain, a transmembrane region, and a cytoplasmic domain. CD152 plays an essential role in regulating T cell activation by binding to its ligands CD80 and CD86, which are expressed on antigen-presenting cells. This binding can inhibit the over-activation of T cells, thus maintaining immune homeostasis.
