T cell clones with dual specificity for M1s and various major histocompatibility complex determinants.

ABSTRACT

A high proportion of T cell clones derived from bulk cultures selected to M1s a,d determinants were found to have joint specificity for allo-H-2 determinants, and vice versa. Significantly, the patterns of H-2 alloreactivity shown by clones selected to M1sa,b determinants appeared to be random. The possible implications of these findings are discussed.
