title: Serum lipoproteins: Trojan horses of the immune response?
abstract: T cells recognizing lipid antigens presented by CD1 molecules have an important role in the immune response. Several lipid antigens for CD1-restricted T cells have been identified, as have some rules of CD1 loading and CD1-restricted presentation. Little is known, however, about the delivery of lipid antigens from either extracellular compartments or CD1-negative cells to CD1-expressing antigen-presenting cells (APCs). A recent study provides evidence for a role for apolipoprotein E in binding lipid antigens and delivering them to APCs.
