Vβ8 T cell receptor (TCR Vβ8) subfamily has three members, Vβ8.1, 8.2, and 8.3. These subfamily members are variants of the TCR β chain that along with the TCR α chain forms the TCR heterodimer, responsible for the recognition of peptides presented by the MHC molecules. Murine Vβ8+ T cells recognize the superantigen staphylococcal enterotoxin B (SEB); in vivo administration of SEB results in the negative selection of Vβ8+ cells in the thymus. Vβ8 is one of the most frequently found β chains on the infiltrating T cells in the brain of mice with experimental autoimmune encephalomyelitis (EAE), and on the T cells response to Toxoplasma gondii.

Other Names: T cell receptor beta 8
Structure: Members of the immunoglobulin superfamily, Vβ8.1 and 8.2 are variants of the TCR β chain which associates with the TCR α chain to form the TCR heterodimer.
Distribution: Expressed in a subset of TCR αβ+ T cells
Function: Recognition of peptides presented in the MHC molecules, responsible for T cell mediated immune response
Ligand Receptor: MHC-Peptide complex
