The recent advent of CD1 tetramers and the identification of novel lipid ligands has contributed towards the increasing number of CD1-restricted T-cell clones captured Description: The CD1 (Thymocyte Antigen CD1) antigen presentation system presents lipid and glycolipid antigens to effector T-Cells, which have diverse roles in Antimicrobial responses, Antitumor immunity and in regulating the balance between Tolerance and Autoimmunity quantity of antigen molecules for presentation, whereas presentation of LTP-associated lipids might re-quire uptakeofmanyLTPmolecules.Thus, internalisation through lipoproteins might be more efficient for lipid-anti-gen presentation, although other lipoprotein-associated lipids might compete for CD1 binding, thus diluting the immunogenic.
