Chaperoning the dance of antigen presentation

Antigen loading onto class I major histocompatibility complex (MHC-I) proteins relies on chaperones and protein flexibility. Researchers now provide new insight into the process, especially for the intriguing ‘non-classical’ MHC-I protein MR1, with implications for fundamental immunology and the development of novel immunotherapies.
