Background: B7-2/CD86

B7-2, also referred to as CD86, is a glycosylated type 1 membrane protein that is a member of the immunoglobulin (Ig) superfamily (1). B7-2/CD86 is constitutively expressed on antigen presenting cells (APCs) such as dendritic cells (DCs), macrophages, and B cells and functions in controlling immune responses through either costimulatory or coinhibitory signals (1,2). Expression of B7-2 is upregulated by APCs upon activation and can be induced in T cells (1,3). The human B7-2 protein, encoded by the CD86 gene, is 329 amino acids (aa) in length with a theoretical molecular weight (MW) of 37.6 kDa (4). The B7-2 protein contains characteristic Ig variable-like (IgV) and constant-like (IgC) domains within its extracellular region (1,3). B7-2/CD86 has structural similarity and shares ~25% sequence homology with another B7 family molecule, B7-1/CD80 (3,5). Both B7-1 and B7-2 are ligands for the activating receptor CD28 and the regulatory receptor cytotoxic T-lymphocyte antigen 4 (CTLA-4) which are expressed on subsets of T cells (1-3,5-7). However, B7-1 and B7-2 bind to CTLA-4 with higher affinity than CD28 (3,5,6). B7-2/CD86 binding to CD28 results in costimulatory signals to promote T cell activation, proliferation, and cytokine production (1-3. 5-7). Binding to CTLA-4 initiates coinhibitory signaling to attenuate the pro-inflammatory T cell response, while also promoting the suppressive function of regulatory T (Treg) cells through expression of indoleamine 2,3-deoxygenase (IDO) (1-3,6,7). Molecules involved in T cell co-signaling have become considerable targets of interest for cancer immunotherapy (7). The anti-CTLA-4 monoclonal antibody ipilimumab, first approved for the treatment of metastatic melanoma, prevents B7-1/B7-2 molecules from binding to CTLA-4, thus driving B7-CD28 binding and promoting costimulatory signals and antitumor effects (1,7,8). Combination therapies targeting co-signaling molecules are currently under investigation to improve antitumor response for treatment of both melanoma and non-melanoma cancers (7,8).
