CD272, also known as B and T lymphocyte attenuator (BTLA), is an Ig superfamily co-inhitory 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, and reduced effectiveness of T regulatory cells.  BTLA plays an important role in the induction of peripheral tolerance of both CD4+ and CD8+ T cells in vivo.  Tolerant T cells have significantly higher expression of BTLA compared with effectors 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 has been reported.

FC - Quality tested

Recommended Usage

Each lot of this antibody is quality control tested by immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is ≤0.5 µg per million cells in 100 µl volume. It is recommended that the reagent be titrated for optimal performance for each application.

Excitation Laser
Red Laser (633 nm)
Application Notes

Additional reported applications (for relevant formats) include: immunoprecipitation1,2 and blocking3,5 of OT-I T cell responses in vitro and incidence of cerebral malaria in vivo caused by P. berghei ANKA (PbA) infection. The LEAF™ purified antibody (Endotoxin < 0.1 EU/µg, Azide-Free, 0.2 µm filtered) is recommended for functional assays (Cat. No. 139104). For highly sensitive assays, we recommend Ultra-LEAF™ purified antibody (Cat. No. 139117 - 139122) with a lower endotoxin limit than standard LEAF™ purified antibodies (Endotoxin < 0.01 EU/µg).

Clone 6A6 antibody reacts only with the C57BL/6 allele of BTLA but not the BALB/c allele of BTLA.

Antigen Details

An Ig superfamily co-inhibitory 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 expression on CD8+ T cells, macrophages, dendritic cells, NKT cells, and NK cells.

BTLA functions as a negative regulator of T cell activation and proliferation, attenuate B cell proliferation upon associating with its known ligand, herpes virus entry mediator (HVEM).
