Publication number: 20240400695Abstract: The present invention relates to methods for promoting T cells response. The inventors examined the expression and function of CLEC-1 in human DCs and demonstrated for the first time a cell-surface expression. They investigated its functional role following triggering on orchestration of T-cell responses. The inventors showed in vitro and in vivo with CLEC-1 deficient rats and rat CLEC-1 Fc fusion protein that disruption of CLEC-1 signalling enhances in vitro Th17 activation and in vivo enhances T cell priming and Th17 and Th1 activation. In particular, the present invention relates to CLEC-1 antagonists for promoting T cells response in a subject in need thereof.Type: ApplicationFiled: August 21, 2024Publication date: December 5, 2024Applicants: INSERM (INSTITUT NATIONAL DE LA SANTE ET DE LA RECHERCHE MEDICALE), UNIVERSITE DE NANTES, OSE IMMUNOTHERAPEUTICSInventors: Elise CHIFFOLEAU, Geraldine TEPPAZ, Nicolas POIRIER, Bernard VANHOVE, Vanessa GAUTTIER
