兔抗小鼠CTLA-4

Flow cytometric analysis of mouse primary splenocytes treated with ConA (2.5 μg/ml, 3 days) labeling CTLA4 with ab224295 at 1/100 dilution (Right panel) compared with a Rabbit IgG, monoclonal [EPR25A] - Isotype Control (ab172730) (Left panel). Goat anti rabbit IgG (Alexa Fluor® 488, ab150077) at 1/2000 dilution was used as the secondary antibody.

A low level of CTLA4 is expected to be on the cell surface; the majority is intracellular, localized to secretory lysosomes (PMID: 11046036). Gated on viable cells.

背景

Cytotoxic T-lymphocyte protein 4, also known as CTLA4 and CD152, is a single-pass type I membrane protein and a member of the immunoglobulin superfamily. It is the second member of the CD28 receptor family. The ligands or counterreceptors for these two proteins are the B7 family members, CD8 (B7-1) and CD86 (B7-2). CTLA4 transmits an inhibitory signal to T cells, whereas CD28 transmits a stimulatory signal. Intracellular CTLA4 is also found in regulatory T cells and may play an important role in their functions. CD152 or cytotoxic T lymphocyte antigen-4 (CTLA-4) is an essential receptor involved in the negative regulation of T cell activation. Because of its profound inhibitory role, CD152 has been considered a sound susceptible candidate in autoimmunity and a persuasive target for cancer immunotherapy. In particular, recent evidence suggests that CD152 is also important in the homeostasis and function of a population of suppressive cells, termed regulatory T cells (Treg).
