Maria LEITE DE MORAES PhD Immunology

Course and current status

Maria LEITE DE MORAES is a former student of the UFRJ (Federal University of Rio de Janeiro, Brazil). She received her BSc in Immunology at the FIOCRUZ (Oswaldo Cruz Fondation, Rio de Janeiro) and the UFRJ, in 1989, and her PhD at the Pasteur Institute and the University Pierre and Marie Curie, Paris, in 1993. She carried out her postdoctoral research in CNRS UMR 8603 in Necker Hospital. There she worked on the ontogeny and function of invariant Natural Killer T (iNKT) and on their role in experimental and clinical allergic asthma. She described iNKT17 cells as a distinct lineage. In 2000, she was recruited as CNRS Research and in 2014 as Research Director 1st class. In 2014, she was appointed as a Group Leader at the Institute Necker Enfants Malades (INEM), Paris.

Scientific summary

Maria LEITE DE MORAES made seminal discoveries on the ontogeny and function of invariant Natural Killer T (iNKT) and on their role in experimental and clinical allergic asthma. Her current focus is the role of iNKT and mucosal-associated invariant T (MAIT) cells on pathogenic and regulatory immune mechanisms in allergy and asthma in experimental models and pediatric patients. She has authored > 80 articles in international peer-reviewed journals with an H Factor of 39. ORCID: 0000-0002-2891-2269.
