Outline of Final Research Achievements |
Dendritic cells induce an immune response by presenting pathogen-derived antigens to T cells by major histocompatibility antigen class II (MHC-II). The cell surface expression level of MHC-II is a regulator of the immune response. We have previously found that crosslinking of MHC-II by the TCR of activated T cells induces endocytosis of MHC-II. In this study, we analyzed the signaling mechanism induced by MHC-II crosslinking. We found that crosslinking of MHC-II induces calcium influx via activation of Syk/PLC, resulting in clathrin-dependent endocytosis of MHC-II mediated with PKC activation.
