CD1

CD1 (cluster of differentiation 1) is a family of glycoproteins expressed on the surface of various human antigen-presenting cells. They are related to the class I MHC molecules, and are involved in the presentation of lipid antigens to T cells. However their precise function is unknown.

Types

CD1 glycoproteins can be classified primarily into two groups which differ in their lipid anchoring.

CD1e is an intermediate form, expressed intracellularly, the role of which is currently unclear.

In humans

Group 1

Group 1 CD1 molecules have been shown to present foreign lipid antigens, and specifically a number of mycobacterial cell wall components, to CD1-specific T cells.

Group 2

The natural antigens of group 2 CD1 are not well-characterized, but a synthetic glycolipid, alpha-galactosylceramide, originally isolated from a compound found in a marine sponge, has strong biologic activity.

CD1 (album)

CD1 is the unofficial name of an untitled album by English industrial band Throbbing Gristle, released in 1986 through record label Mute.
