Immunité innée

Innate lymphoid cells (ILC) are a newly described family of hematopoietic cells that lack antigen-specific receptors but can be activated to promptly produce large amounts of cytokines (including interleukin (IL)-5, -13, -17A, -22, TNF-α […]

The Think tank Mucosal Immunology gathers several research units form the departments of immunology, microbiology, cellular biology and epidemilogy and infection, as well as from the Institut Imagine (Necker) and Hôpital Paul Brousse. It […]

Mucosal homeostasis requires a delicate equilibrium between immune mechanisms and commensal microorganisms that impacts on the development and maintenance of critical physiological processes including digestion, metabolism or host defense. Several infectious or inflammatory disorders […]

Acquired immune deficiency syndrome (AIDS), tuberculosis (TB) and malaria are the primary infectious diseases causing death world wide. TB is responsible for a third to a half of human immunodeficiency virus type 1 (HIV-1)–associated […]

We study the impact of the portal of entry of microbes in the intestine on host responses and microbial dissemination. To this end, we combine in vivo, ex vivo and in vitro systems, as well […]

Research in the Innate Immunity Unit strives to understand the signals that regulate lymphoid lineage development and the mechanisms that promote the functional diversification of lymphocyte responses. Modeling Hepatitis B virus infections in a […]
