Abstract

Murine cytotoxic responses to TNP-modified syngeneic cells (TNP-self) have been shown to exhibit preferential recognition of K or D end self products encoded by the H-2 complex. In the present study, a number of B10 congenic and recombinant mouse strains were investigated to determine the H-2K and H-2D-restricted FTC-self CTL response patterns, and these were compared with the CTL response patterns obtained for TNP-self. The results indicate that for strains possessing the H-2(k,d,h2,h4) haplotypes, respectively, preferential CTL responses were observed against FTC recognized in association with K(k) over D(k), D(d) over K(d), and K(k) over D(b). These patterns of preferential CTL responses were the same as those reported for TNP-self as well as several anti-viral CTL responses. In contrast to the results obtained in the B10.A strain, in which K(k) preference was observed over D(d) for TNP-self CTL, no preferential CTL response was observed when FTC was recognized in association with K(k) and with D(d). In this context, it was observed that the CTL response to FTC recognized in association with D(d) was particularly strong. This strong D end-associated response was shown to involve D locus products, and no evidence was obtained indicating that L locus self products were involved. These studies are discussed with respect to the possibility that different haptens can be recognized by CTL in association with different self determinants encoded by the same H-2 gene products.
