Intérêts de recherche

Le professeur Denis Girard est directeur du laboratoire de recherche en inflammation et physiologie des granulocytes. Ses travaux portant sur les mécanismes moléculaires et cellulaires impliqués dans l’activation des granulocytes en réponse à divers agents, incluant des cytokines, drogues nanoparticules et plusieurs xénobiotiques, visent à mieux comprendre et réguler l’inflammation. L’identification de nouvelles molécules régulant plusieurs fonctions des neutrophiles, cellules clefs de l’inflammation, peut mener au développement de nouvelles stratégies thérapeutiques pour traiter des maladies et désordres inflammatoires. Les travaux du professeur Girard couvrent à la fois des aspects in vitro et in vivo de l’inflammation. Sa liste de publications scientifiques informe des différents projets de recherche effectués dans son laboratoire, incluant un de ses nouveaux créneaux de recherche visant à étudier les interactions entre les nanoparticules et les cellules cancéreuses.

 

Fonctions et biographie

Le professeur Denis Girard a obtenu son grade de B. Sc. en biologie (spécialité : biologie expérimentale) ainsi que celui de M.Sc. en biologie (spécialité : immunotoxicologie) à l’Université du Québec à Montréal. Il est un diplômé de l’Université de Montréal où il a effectué un Ph. D. en microbiologie et immunologie alors qu’il était boursier du FRSQ (spécialité : auto-immunité / auto-anticorps / cytosquelette). Par le suite, pendant trois ans et demi, il a effectué un stage postdoctoral au Département de rhumatologie et immunologie du Centre hospitalier (CHUL) de l’Université Laval. Il était alors boursier du CRM / Société d’Arthrite (programme conjoint).

Le professeur Girard s’est alors fait reconnaître pour ses travaux portant sur les interactions entre certaines cytokines / récepteurs et les cellules de type neutrophiles impliquées dans le processus de l’inflammation. Il est notamment le premier à démontrer que l’interleukine-15 est un agoniste puissant des neutrophiles. Il s’est fait par la suite octroyer des bourses de chercheur-boursier junior 1, junior 2 et senior par le FRSQ.
