Secondary Tc cells generated against Sindbis virus (SIN) are restricted to Dk. All other H-2K or D regions tested show low specific responsiveness. F1 hybrids between low and high responders show dominance of responsiveness but lack complementation. When BALB/c (KdIdDd) low responder fetal liver stem cells were allowed to mature in irradiated high responder recipients C3H.OH (KdIdDk) a response to Dk plus SIN could be generated with Tc cells of BALB/c origin. This result, together with the failure of complementation in the F1 hybrids, implies that the lesion of low responsiveness is in the inability of viral antigen to stimulate a Tc-cell response in association with any self H-2K or H-2D molecule (of those tested) other than H-2Dk. Hypotheses compatible with these data are discussed.
针对辛德毕斯病毒(SIN)产生的二级Tc细胞受限于Dk。所测试的所有其他H-2K或D区域显示出低特异性反应性。低反应者和高反应者之间的F1杂种表现出反应性的显性但缺乏互补作用。当允许BALB/c(KdIdDd)低反应性胎肝干细胞在经辐照的高反应性受体C3H.OH(KdIdDk)中成熟时,源自BALB/c的Tc细胞可产生对Dk加SIN的反应。这一结果,连同F1杂种中缺乏互补作用,意味着低反应性的损伤在于病毒抗原无法与除H-2Dk之外的任何自身H-2K或H-2D分子(所测试的那些)结合刺激Tc细胞反应。讨论了与这些数据相符的假说。
