Major histocompatibility complex-I (MHC-I) molecules play a central role in the
immune response to viruses and cancers. They present peptides on the surface of
affected cells, for recognition by cytotoxic T cells. Determining which peptides
are presented, and in what proportion, has profound implications for developing
effective, medical treatments. However, our ability to predict peptide
presentation levels is currently limited. Existing prediction algorithms focus
primarily on the binding affinity of peptides to MHC-I, and do not predict the
relative abundance of individual peptides on the surface of antigen-presenting
cells in situ which is a critical parameter for determining the strength and
specificity of the ensuing immune response. Here, we develop and experimentally
verify a mechanistic model for predicting cell-surface presentation of competing
peptides. Our approach explicitly models key steps in the processing of
intracellular peptides, incorporating both peptide binding affinity and
intracellular peptide abundance. We use the resulting model to predict how the
peptide repertoire is modified by interferon-?, an immune modulator well known to
enhance expression of antigen processing and presentation proteins.
