    The Gao Fu team of the Institute of Microbiology, Chinese Academy of Sciences recently reported on the "atypical" interaction mechanism between the costimulatory receptor glucocorticoid-induced tumor necrosis factor receptor family-related protein (GITR) and its ligand GITRL.


    TNF "superfamily" related molecules are the key to natural/acquired immune regulation and function.


    TNF "superfamily" related molecules are the key to natural/acquired immune regulation and function.


    GITR and its ligand GITRL are important members of the TNF/TNFR superfamily


    It shows that GITR/GITRL is different from the "atypical" interaction mode of the classic TNF/TNFR superfamily


    The phenomenon that a single domain of GITR mediates its binding to ligand suggests that this unique mode of action may be an older binding mode in the evolution of the TNF/TNFR superfamily, while other TNFR superfamily member molecules and ligands Binding has often evolved into two different domains mediated binding specificity and high affinity


    Assistant researcher Zhao Min of the Institute of Microbiology and Fu Lijun, a postgraduate jointly trained by Jiangxi Science and Technology Normal University, are the co-first authors of the study.
