Skills

Immune cell (peripheral, mucosal and brain) isolation, purification and culture/stimulation in vitro (inflammatory or mitogen challenge, TLR ligand stimulation)

Cytokine Assays (ELISA) on cell culture supernatants, colostrum and milk

Pig immunoglobulin dosage (serum, colostrum and milk)

Membrane and /or intracellular staining and multi-colour flow cytometry (acquisition - analysis)
Mice, sheep, human and pig experimentation

Research topics and scientific objectives

My research activity deals with the consequences of perinatal nutrition on the development and responsiveness of intestinal immune system in the offspring (nutritional imprinting) as well as on the adult immune system, notably its susceptibility to inflammation (peripheral, infiltrating brain immune cells), in interaction with adult nutritional environment.
