Combining computer algorithms with experimental approaches to screen T cell epitopes

The identification of T cell epitopes from immunologically relevant antigens remains a critical step in the development of vaccines. This review presents an overview of strategies that combine computer algorithms with experimental approaches for the screening of candidate epitope peptide from defined proteins. Several computer algorithms are currently being used for epitope prediction of various major histocompatibility complex (MHC) class I and II molecules, based either on the analysis of natural MHC ligands or on the binding properties of synthetic peptides. Moreover, the analysis of proteasomal digests of peptides and whole proteins has led to the development of algorithms for the prediction of proteasomal cleavages. In order to verify the generation of the predicted peptides during antigen processing in vivo as well as their immunogenic potential, several experimental approaches have been pursued in the recent past. Other strategies employ various methods for the testing of the recognition pattern towards target cells that express the antigen, and for the testing of the cytokine secreted by the activated T-cell.
