although the number of class i alleles we examined is still limited , these results indicate that antigenic fragments derived from the processed h-43a and h-43b alloantigens possess an indistinguishable epitope ( agretope ) , and that such agretope either interacts only with the privileged kb molecules or allows to bestow the immunogenic conformation of allodeterminants on the fragments solely in the context of the restricting kb element .
