CTLA-4 is a member of the immunoglobulin superfamily that is expressed by activated T cells and transmits an inhibitory signal to T cells. CTLA-4 is homologous to the T-cell co-stimulatory protein, CD28, and both molecules bind to CD80 and CD86, also called B7-1 and B7-2 respectively, on antigen-presenting cells. … See more CTLA-4 or CTLA4 (cytotoxic T-lymphocyte-associated protein 4), also known as CD152 (cluster of differentiation 152), is a protein receptor that functions as an immune checkpoint and downregulates immune responses. … See more CTLA-4 was first identified in 1991 as a second receptor for the T cell costimulation ligand B7.

WebCytotoxic T lymphocyte antigen 4 (CTLA4) deficiency is an autosomal dominant inherited disorder due to mutations of the gene encoding for the CTLA4 protein (see Table 41.6 ). Null mutations or point mutations that encode a nonfunctional protein can result in haploinsufficiency. WebCytotoxic T-lymphocyte-associated protein 4 (CTLA4) or CD152 belongs to the immunoglobulin superfamily. Although approximately 30% identity has been shown in sequences of CTLA4 and CD28, and also similar ligands on the surface of APCs, CTLA4 delivers inhibitory signals to T cells compared to stimulatory signals provided by CD28. ...
