• Specificity: Chicken TCR gamma delta
  MAb TCR1 precipitates a heterodimer of Mr 90-kDa (two bands of Mr 40-kDa and 50-kDa upon reduction) on chicken peripheral blood T cells.1,2 Deglycosylation of the heterodimer yields two polypeptides of Mr 35-kDa and 32-kDa from TCR1 precipitates. Unlike human and mouse, in which gamma delta cells comprise a minor subset of T lymphocytes in the circulation, the chicken has a relatively large subset of gamma delta T cells.1-3 The frequency of TCR gamma delta cells is usually 20-25% of the total blood T cells, but may reach approximately 50% in chickens of 6 months of age.2 The majority of TCR gamma delta + cells in the thymus and blood are CD4-CD8-, although a small subset of them may express CD8 or CD4 coreceptors.3 However, when the TCR gamma delta + cells migrate into the spleen and intestine, most of them begin to express CD8. Although the biological function of gamma delta T cells is unclear, they are clearly capable of cytotoxic activity in vitro. The CD8+ gamma delta T cells may also be involved in down-regulation of the immune response.4 They cannot, however, induce a graft-vs-host (GVH) reactions.5
