CD1 and lipid antigens: intracellular pathways for antigen presentation.
Recently, different members of the CD1 family of MHC-like molecules have been shown to sample different intracellular compartments to present lipid and glycolipid antigens to T cells. Emerging models suggest that CD1 may have evolved to monitor the integrity of membrane lipids and/or to present microbial lipid antigens to both alpha beta and gamma delta T cells.
متن کاملRole of lipid trimming and CD1 groove size in cellular antigen presentation.
Cellular CD1 proteins bind lipids that differ in length (C(12-80)), including antigens that exceed the capacity of the CD1 groove. This could be accomplished by trimming lipids to a uniform length before loading or by inserting each lipid so that it penetrates the groove to a varying extent. New assays to detect antigen fragments generated within human dendritic cells showed that bacterial anti...

15 صفحه اولMechanisms and Consequences of Antigen Presentation by CD1.
The CD1 proteins are a family of non-polymorphic and MHC class I-related molecules that present lipid antigens to subsets of T lymphocytes with innate- or adaptive-like immune functions. Recent studies have provided new insight into the identity of immunogenic CD1 antigens and the mechanisms that control the generation and loading of these antigens onto CD1 molecules. Furthermore, substantial p...
