abstract：:T cell responses against complex antigens are often directed against a limited set of immunodominant determinants. We have studied this phenomenon at the level of cellularly processed peptides recognized by CTL in the B6 anti-BALB.B minor histocompatibility (H) barrier, comprising at least 29 antigen loci. B6 anti-BAL...
