Flow cytometric analysis of CD152 expression in activated human PBMC (human peripheral blood mononuclear cell). PHA-activated (2 days) human PBMC were fixed with 4% PFA and permeabilization with the 0.1% Tween and then were stained with either Mouse IgG2a, κ Isotype Control (left panel) or SDT Mouse Anti-Human CD152 Antibody at 1:200 dilution (1μg) (right panel). Goat Anti-Mouse IgG Alexa Fluor® 647 was used as the secondary antibody. Then cells were stained with CD3 - Brilliant Violet 421™ Antibody separately. 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.
