On May 28th, 2024, we welcomed Dr. Paulo Bettencourt from Católica Medical School to i3S for a riveting Satellite Seminar titled “Identification of antigens presented by MHC-I and MHC-II through immunopeptidomics for tuberculosis vaccines.” Dr. Bettencourt’s innovative study on Mycobacterium TB vaccines shed light on the intricate realm of immunology. Dr. Bettencourt had the chance to meet and interact with other i3S researchers during the day, in addition to his excellent seminar, which spurred lively discussions.
