Abstract

Mice of the C3H/He and A non-H-2 backgrounds are disparate from mice of the B10 background for the tissue-restricted, non-H-2 alloantigen of epidermal cells (EC), Epa-1, that is expressed by EC but not by lymphocytes (LC), as well as for a number of other alloantigens of the B10 background that are expressed by both EC and LC, generically referred to as "lymphocyte/epidermal alloantigens" (LEA). In this study, we compared the ability of various H-2 congenic strains on the C3H or A backgrounds to mount cytotoxic T-lymphocyte (CTL) responses to EC from H-2 compatible mice of the B10 background. High responses to Epa-1 were detected only in the H-2aand H-2khaplotypes; H-2b, H-2o1, H-2s, H-2t1, and H-2t2 haplotypes were nonresponders to Epa-1. High responses to LEA were detected in H-2a, H-2b, H-2s, H-2t1, and H-2t2 haplotypes; H-2kand H-2o1 were nonresponsive to LEA. Analysis of the H-2K, I and D region alleles of responders indicates that H-2Kkis essential for anti-Epa CTL responses, whereas Dd, Db, or Kswere all permissive for strong anti-LEA responses. The ability to mount a given CTL response was not associated with differences in I-region alleles. These results are discussed in terms of K/D region products serving as Ir-gene products for CTL and in determining the apparent tissue-specificity of CTL.
