Popis: | The expression of TCR by T cells that mature extrathymically in nude mice was determined by staining Ig − cells from B10 nude mice that were 5 months of age or older with mAbs specific for CD3, α β or γ δ TCR. Although the majority of Ig − cells in older nude mice express TCR, the distribution of α β and γ δ TCR in relation to CD4 and CD8 expression is markedly different compared to T cells from euthymic mice. Approximately half of the CD3 + T cells found in the spleen and lymph nodes of nude mice express γ δ TCR that is equally distributed between CD4 − 8 − double-negative and CD8 + single-positive T cells. These data provide the first quantitative measure of the expression of TCR by T cells that mature in the absence of a thymus and suggest that the extrathymic environment, although not efficient, is permissive for the maturation of T cells that express α β and γ δ TCR. |
