Abstract

The B10.STA12 mouse congenic line inherited from the wild mouse parent not only the H-2(w13) haplotype but also an allele at a minor H locus, which we designate H-41. This allele (H-41a) differentiates the B10.STA12 line from B10.STA10 and B10.LIB55, which carry identical H-2(w13) haplotypes but a differennt H-41 allele (the H-41b, also present in the background strain C57BL/10Sn). The B10.STA12 and B10.STA10 lines reject each other's skin grafts and generate cytolytic T lymphocytes (CTL) after in vivo immunization and in vitro restimulation with cells of the partner strain. The B10.STA12 anti-B10.STA10 CTL react with B10.STA10, B10.LIB55, and B10.STA39 target cells and with cells of F1 hybrids between the responder strain B10.STA12 and strains C57BL/6, C57BL/10, C57L, BALB/c, A, AKR, WB, DBA/1, and DBA/2 but fail to react with (C3H x B10.STA12) F1 and (CBA x B10.STA12) F1 cells. The B10.STA10 anti-B10.STA12 CTL react with B10.STA12, B10.P, and C3H.NB cells but fail to react to (B6 x B10.STA10) F1 target cells. The CTL reactivity in both combinations is D(p) restricted. The B10.STA10 anti-B10.STA12 CTL exhibit, in addition, a cross-reactivity with B10.SAA48 cells that may be directed at one of the alloantigens controlled by the H-2 haplotype of this strain.
