A T cell-centric view of ILC differentiation

Innate lymphoid cells (ILCs) and natural killer (NK) cells have gained considerable interest due to their important roles in immune defense and tissue homeostasis. Our current understanding of how these develop has been greatly facilitated by our extensive knowledge of T cell biology. Established models of T cell differentiation have provided the conceptual basis for a classification of ILCs and NK cells as innate homologues of adaptive T helper cells and cytotoxic T cells, respectively. Furthermore, NK cell and ILC activation finds parallels with known regulatory mechanisms within the T cell system. Here, I will examine the process of NK cell and ILC development from a ‘T cell perspective’ in an attempt to extend the analogy between adaptive T cells and their innate ILC and NK cell counterparts.

I received a combined M.D./Ph.D. in 1989/1991 from Cornell University Medical College and the Memorial Sloan–Kettering Cancer Center, and completed post-doctoral training with Alain Fischer in Paris, where I characterized several genes responsible for primary human immunodeficiency syndromes. In 1994, I became a permanent staff scientist with the Institut National de la Santé et de la Recherche Médicale (Inserm) and spent a year as an EMBO visiting scientist at the University of Genetics in Cologne Germany with Pr. Klaus Rajewsky. In 1999, I moved my laboratory to the Immunology Department of the Institut Pasteur, where I directed the Immunology Department from 2002-2006. Current research themes in the Innate Immunity Unit include the study of natural killer and innate lymphoid cells and ‘humanized’ mouse models to study human disease.
