Epitope mapping

The immune response to extrinsic and intrinsic antigens involves specific antigen receptors on T and B cells. The precise antigenic determinants, or epitopes, recognized by these receptors are discrete sequences within the native antigen. The ability to identify and manufacture key epitopes in the immune response has important implications for disease diagnosis and immunointervention. Consequently, increasingly sophisticated technologies are being applied to epitope mapping. This report from a recent workshop gives a balanced view of progress to date and the challenges ahead.
