Le choc anaphylactique est une réaction allergique systémique qui survient en quelques minutes et pouvant être fatale. Mon travail de thèse s’articule autour de deux projets dont la finalité est de mieux comprendre le mécanisme physiopathologique. La première partie de ce travail consiste à étudier in vivo chez la souris les contributions des récepteurs Fc aux IgG (FcγRs), des cellules effectrices et des médiateurs contribuant dans un modèle d’anaphylaxie systémique passive induit par une sous-classe particulière d’IgG : des IgG1, des IgG2a ou des IgG2b monoclonales dirigées contre un même antigène. Cette étude a permis de démontrer que le FcγRIII, les neutrophiles et les monocytes/macrophages sont les acteurs majoritaires quelque soit la s...
