Research themes

The laboratory of dendritic cell biology, which is coordinated by Dr. Philippe PIERRE (DR1 CNRS) and Evelina GATTI (DR2 CNRS), focuses on gaining fundamental knowledge of the biology of dendritic cells (DC) in normal and pathogenic conditions. DCs have the unique capacity to initiate primary immune responses by stimulating naive T cells. We are interested in the biochemical changes occurring during DC activation by microbial products and pathogens focusing on protein synthesis regulation an autophagy. Our team carries-out the functional dissection of these various processes, providing new insights to how a complex immune response could be potentially modulated for therapeutic purposes. Our laboratory has accumulated an extensive scientific know-how in the study of DCs, and repetitively proven using multidisciplinary approaches that it is able to transform innovative concepts in coherent projects. We mostly focus on how protein synthesis regulation and autophagy impact antigen presentation and cytokines production, as well as, coordinate through stress pathways induction, the expression of given proteins (e.g. RUFY4) capable of regulating key biological functions, like membrane traffic or endocytosis during the immune response. Our strong interest in protein synthesis regulation and misfolded proteins has led to the invention of a non-radioactive method to monitor protein synthesis. This technique has been diffused world-wide leading to important breakthroughs for protein synthesis research, including the description of nuclear translation.
