Description
Natural killer T cells expressing an invariant T cell antigen receptor (iNKT cells) are cells of the innate immune system. After recognizing glycolipid antigens presented by CD1d molecules on antigen presenting cells (APCs), iNKT cells rapidly produce large quantities of cytokines, thereby stimulating many types of cells. Recent studies have described several mechanisms of iNKT cell activation and the contribution of these cells to antimicrobial responses. iNKT cells can be activated by endogenous antigens and/or inflammatory cytokines from APCs. However, iNKT cells also recognize certain microbial glycolipids by their invariant T cell antigen receptor (TCR), and they contribute to pathogen clearance in certain microbial infections. These findings indicate that the iNKT TCR is useful for detecting certain microbial pathogens. Moreover, recent studies suggest that iNKT cell glycolipid antigens may be useful in antimicrobial therapy and vaccines.
