Cellules souches, adhésion cellulaire et transduction du signal
Les cellules souches intestinales (CSI) ont récemment été identifiées et impliquées dans les pathologies inflammatoires et cancéreuses intestinales. Notre objectif est de mieux appréhender les différents sous-types de CSI et leurs fonctions en physiologie et physiopathologie. En particulier, nous étudions la signalisation croisée entre les récepteurs d’adhésion et les autres récepteurs membranaires tels que les récepteurs de protéases inflammatoires
Stem cells, cell adhesion and signal transduction
Intestinal stem cells (ISC) have recently been identified and implicated in both inflammatory and cancer intestinal pathologies. Our aim is to get a better understanding of ISC sub-types and functions in both physiological and pathological conditions. Specially, we investigate the signaling crosstalk between adhesion receptors and other receptors such as protease-activated receptors.
