Binding of peptides to Major Histocompatibility Complex (MHC) proteins is a critical step in immune response. Peptides bound to MHCs are recognized by CD8+ (MHC Class I) and CD4+ (MHC Class II) T-cells. Successful prediction of which peptides will bind to specific MHC alleles would benefit many cancer immunotherapy appications. MHCnuggets provides a fast, accurate, and unified framework for the prediction of peptide-MHC binding for both class I and class II alleles. This includes rare alleles i.e. ones not well represented in its training data. It does so by taking advantage of recent advances in deep learning. Concretely, MHCnuggets is a collection of long short-term memory networks trained using a transfer learning protocol. This helps MHCnuggets deal with two of the primary challenges faced in neoantigen prediction today -- variability of peptide length, and paucity of data in rare alleles.
