Abstract
Dendritic cells (DCs) are professional antigen-presenting cells (APC) that facilitate the development and progression of atherosclerosis. However, DCs also function as novel “switches” between immune activation and immune tolerance and represent a heterogeneous hematopoietic lineage, with cell subsets in different tissues that show a differential morphology, phenotype, and function. Regulatory DCs, depending on their immature state, can be induced by immunosuppressive modulation, which plays an important part in the maintenance of immunologic tolerance via suppression of the immune response. In this review, we describe the current understanding of the generation of regulatory DCs. The novel role of selectins in the modification of DCs in atherosclerosis is also discussed.
