in speculating about mechanisms that might give rise to t-cell epitopes appearing within different hla-dr frameworks , we return to the hypothesis expressed above that suggests that gene-conversion-like events might be involved in shuffling the hypervariable segments of hla-d region exons into alternative hla-d region frameworks where they will still be recognized by the t cell ( but not typed by conventional serology or mixed lymphocyte typing ) as the `` '' disease associated '' '' hla product .
