The TCR Vβ8 family consists of three members, namely Vβ8.1, 8.2 and 8.3. 1B3.3 reacts with Vβ8.3 only, but not Vβ8.1 or Vβ8.2. Most mouse strains have about 20% Vβ8+ T cells in the periphery. However, C57BR, C57L, SJL, SWR (Tcra haplotype) and RIII strains (Tcrc haplotype) do not express Vβ8 due to a gene deletion at the Vβ8 loci.  Exogenous superantigen, such as staphylococcal enterotoxin B, stimulates lymphocytes bearing Vβ8 and selectively eliminate those T cells in vivo.
