At its core, MHC peptide prediction aims to forecast which peptides are likely to bind to specific Major Histocompatibility Complex (MHC) molecules. This binding event is the initial step in T-cell recognition, dictating whether the immune system will mount a response against a particular antigen. The accuracy of these predictions is paramount, as it guides the identification of potential T-cell epitopes and informs the design of therapeutic interventions.
