Background

MAb TCR3 precipitates a CD3-associated heterodimer of Mr 88-kDa (two bands of Mr 48-kDa and 40-kDa upon reduction) on chicken peripheral blood T cells. (1,2) Deglycosylation of the heterodimer yields two polypeptides of Mr 34-kDa and 31-kDa from TCR3 precipitates. In the chicken, two distinct subpopulations of alpha beta T cells appear in the thymus subsequent to the appearance of gamma delta T cells. Thesesubpopulations, originally denoted as TCR2 and TCR3, (1,2) arise sequentially in the thymus during ontogeny and are now known to represent two distinct Vbeta families, Vbeta1 and Vbeta2, respectively. (3) The TCR3 MAb reacts with approximately 9% of thymocytes, 15-25% of blood mononuclear cells and 13% of splenocytes young adult chickens. Two-color immunofluorescence has revealed that the TCR3+ thymocytes include CD4+CD8-, CD4-CD8+, CD4+CD8+ and CD4-CD8- subpopulations. The TCR3+thymocytes can be separated into two subsets. One subset is characterized by relatively low levels of expression of the TCR3/CD3 complex and most of the cells in this subset are CD4+CD8+. Cells in the other subset express TCR3/CD3 in higher density and are either CD4+CD8- or CD4-CD8+, corresponding to the more mature medullary subset of thymocytes. The TCR3+ cells in the blood and spleen express relatively high levels of the TCR3/CD3 receptor complex and are single positive, with CD4+CD8- cells being four times more frequent that the CD4-CD8+ cells (ca. 80% CD4+ vs ca. 20% CD8+).
