Abstract
Over the past year, several important advances have been made in understanding the mechanisms by which class II MHC glycoproteins acquire endosomal peptides inside antigen-presenting cells. Recent progress in the study of class II antigen presentation includes the identification of ligands from which invariant chain protects class II molecules in pre-endosomal compartments, an improved understanding of how invariant chain inhibits antigenic peptide binding, and the appreciation that HLA-DM (a factor important for antigen presentation in vivo) can act as a catalyst for peptide exchange.
