Human peripheral blood mononuclear cells were stimulated with Cell Activation Cocktail (without brefeldin) for 4 hours, fixed, permeabilized, and intracellularly stained with purified anti-human CD152 (CTLA-4) recombinant (clone QA20B10) (left), or purified mouse IgG1, κ isotype control (right), followed by PE goat anti-mouse IgG. Cells were constained with anti-human CD3 APC.

CD152, also known as Cytotoxic T-Lymphocyte Antigen 4 (CTLA-4), is a 33 kD member of the immunoglobulin superfamily. It is transiently expressed on activated T cells. CTLA-4 is expressed on the surface of helper T cells and transmits an inhibitory signal to T cells. Regulatory T cells express high levels of CTLA-4. CTLA-4 is similar to CD28 in amino acid sequence, structure, and genomic organization. Whereas CD28 delivers a costimulatory signal in T cell activation, CTLA-4 negatively regulates cell-mediated immune responses through interaction with CD80 (B7-1) and CD86 (B7-2) present on antigen presenting cells (APC). CTLA-4 is thought to play a role in the induction and maintenance of immunological tolerance as well as the development of protective immunity and thymocyte regulation.
