Peptides in Immunology

Peptides play a role in all aspects of the immunological responses to invading pathogens and tumor cells. The Review, Perspective and Commentary pieces in this issue explore the generation and molecular mechanisms of peptides and the considerations and strategies needed to harness them to treat disease.

Peptides fulfill many roles in immunology, yet none are more important than their role as immunogenic epitopes driving the adaptive immune response, our ultimate bulwark against infectious disease. Peptide epitopes are mediated primarily by their interaction with major histocompatibility complexes (T-cell epitopes) and antibodies (B-cell epitopes). As pathogen genomes continue to be revealed, both experimental and computational epitope mapping are becoming crucial tools in vaccine discovery1,2. Immunoinformatics offers many tools, techniques and approaches for in silico epitope characterization, which is capable of greatly accelerating epitope design.
