We examined T cell development and T cell repertoire in transgenic mice expressing a single T cell receptor (TCR) α chain derived from the H‐2Db ‐lymphocytic choriomeningitis virus (LCMV)‐specific cytolytic T lymphocyte (CTL) clone P14. To generate these α P14 mice, mice transgenic for the P14 TCR α chain were backcrossed to TCR α‐deficient mice. Thymi from α P14 mice exhibited a marked decrease of mature CD4+8− and CD8+4− single‐positive thymocytes comparable to thymi from TCR α‐deficient mice. Correspondingly, the number of peripheral T cells was reduced in the CD4 (tenfold) and in the CD8 (twofold) subsets when compared to normal mice. T cells from α P14 mice generated a primary anti‐LCMV CTL response when stimulated in vitro with LCMV in contrast to normal mice which require priming in vivo; elimination of LCMV in vivo was, however, not improved. Flow cytometric analysis of T cells with Vβ‐specific antibodies showed a diverse endogenous TCR Vβ repertoire. Functional analysis of the T cell repertoire, however, revealed a strongly reduced (30‐fold) allogeneic and the absence of a vesicular stomatitis virus‐specific CTL response and an impaired ability to provide T cell help for antibody isotype switching. Thus, T cell selection in the thymus was impaired and the T cell repertoire was limited in mice expressing only one type of TCR α chain.
