A)CD-1 restricted T cells cannot rapidly secrete cytokines.
B)CD-1 restricted T cells recognize non-peptide antigens,such as lipids.
C)CD-1 restricted T cells bind both cell-associated and soluble antigens.
D)CD-1 restricted T cells express both CD4 and CD8 coreceptors.
E)CD-1 restricted T cells are actually natural killer (NK)cells.

A small population of T cells express T cell receptors that recognize lipids bound to class I MHC-like molecules called CD1 molecules.These lipid antigen-specific T cells include CD4⁺CD8⁺,or CD4F1F1F1S1^F1F1F10CD8F1F1F1S1^F1F1F10 F1F1F1S1F1F1F10 T cells.Many of these T cells also express markers found on natural killer (NK)cells and are therefore called NK T cells,although they are not actually NK cells.CD1-restricted T cells are still capable of rapidly producing cytokines such as IL-4 and IFN-F1F1F1S1F1F1F10,but their physiologic function is unknown.
