摘要

Atherosclerosis is a chronic inflammatory disease of medium-and large-sized arteries characterized by lipid and leukocyte accumulation within lesions of the arterial wall [1,2]. Among those infiltrating immune cells are natural killer T (NKT) cells that share features with T cells and natural killer cells. In contrast to T cells, they recognize lipid-derived but not peptide-derived foreign and self-antigen. Upon recognition of these antigens presented via the Major histocompatibility complex (MHC)-class-I-like molecule cluster of differentiation (CD)Id NKT cells rapidly produce their major effector cyto-kines interferon-7 and interleukin-4 which are known as classical proatherogenic or antiathero-genic mediators, respectively [1,2].
