B and T lymphocyte attenuator (BTLA) is an Ig superfamily coinhibitory receptor with structural similarity to programmed cell death 1 (PD-1) and CTLA-4. BTLA is expressed on B cells, T cells, macrophages, dendritic cells, NKT cells, and NK cells. Engagement of BTLA by its ligand Herpes Virus Entry Mediator (HVEM) is critical for negatively regulating immune response. The absence of BTLA with HVEM inhibitory interactions leads to increased experimental autoimmune encephalomyelitis severity, enhanced rejection of partially mismatched allografts, an increased CD8+ memory T cell population, increased severity of colitis, reduced effectiveness of T regulatory cells. BTLA takes an important role in the induction of peripheral tolerance of both CD4+ and CD8+ T cells in vivo. Tolerant T cells have significant up-regulated expression of BTLA compared with effector and naïve T cells. BTLA may cooperate with CTLA-4 and PD-1 to control T cell tolerance and autoimmunity. It was reported that BTLA may regulate T cell function by binding to B7-H4. But further studies are needed to confirm. The existence of three distinct BTLA alleles was reported. The BTLA antibody reacts with mouse BTLA from both BALb/c and C57BL/6 strains.Product Details

- An Ig superfamily coinhitory receptor with structural similarity to programmed cell death 1 (PD-1) and CTLA-4.
- BTLA is expressed on a wide number of lymphocytes in mice. It is most highly expressed on B cells, followed by CD4+T cells, lower express on CD8+ T cells, macrophages, dendritic cells, NKT cells, and NK cells.
- BTLA functions as a negative regulator of T cell activation and proliferation. It attenuates B cell proliferation upon associating with its known ligand, Herpes Virus Entry Mediator (HVEM).
