Abstract:Although most T lymphocytes recognize peptides presented by major histocompatibility complex (MHC)-encoded class I and class II molecules, there also are significant populations of T cells that recognize nonpeptide antigens. Prominent among these T lymphocytes are the type I or invariant natural killer T cells (iNKT cells). These T lymphocytes recognize lipids presented by CD1d, a nonpolymorphic, class I-like, antigen-presenting molecule. We have carried out a whole genome siRNA screen in a macrophage cell lin… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
