We have studied the relationship between major histocompatibility complex (MHC)-restricted antigen recognition and alloreactivity by examining T cell receptor (TCR) alpha and beta gene expression in cytochrome c-specific, Ek alpha:Ek beta (Ek)-restricted helper T cell clones derived from B10.A mice. The clones could be segregated on the basis of four distinct alloreactivity patterns. Clones cross-reactive for three different allogeneic la molecules (As alpha:As beta [As], Ab alpha:Ab beta [Ab], Ek alpha: Eb beta [Eb]) expressed the same V alpha and V beta gene segments, generating the distinct alloreactive specificities via unique V alpha-J alpha and V beta-D beta-J beta joining events. Ek alpha:Es beta (Es)-alloreactive B10.A clones expressed the same V alpha, J alpha, and V beta segments as an Es-restricted, Ek-alloreactive, cytochrome c-specific, H-2-congenic B10.S(9R) clone. This homology between TCRs mediating allorecognition of la molecules and recognition of the same la molecules as restriction elements associated with nominal antigen suggests that MHC-restricted recognition and allorecognition represent differences in the affinity of the TCR-MHC molecule interaction.
