CD antigen	MW.(kDa)	Synonyms & Properties	Leukocyte expression	Function
CDw76		Carbohydrate antigen	B cells, subpopulation of T cells	Not known
CD77		Pk blood group antigen, Burkitt's lymphoma antigen, (BLA), ceramide trihexoside (CTH), globotriaosylceramide (Gb3); sphingolipid antigen	Germinal-center B cells	Not known
CD79a	40-45	Ig-α, MB1	B cells	Component of B-cell antigen receptor analogous to CD3, required for cell-surface expression and signal transduction
CD79b	37	B29, Ig-β	B cells	Component of B-cell antigen receptor analogous to CE3, required for cell-surface expression and signal transduction
CD80	60	B7, B7.1, BB1	Activated B and T cells; macrophages	Co-stimulation of T-cell activation with CD86
CD81	26	Target for anti-proliferative antigen-1 (TAPA-1)	Broadly expressed on hematopoeitic cells; expressed by endothelial and epithelial cells; absent from erythrocytes, platelets, and neutrophils	Member of CD19/CD21/Leu-13 signal-transduction complex, the B-cell co-receptor
CD82	45-90	4F9, C33, IA4, KAI1, R2	Activated/differentiated hematopoeitic cells	Signal transduction: may induce T-cell spreading and pseudopod formation, modulate T-cell proliferation, and provide co-stimulatory signals for cytokine production; possible role in activation of monocytes
CD83	43	HB15	Dendritic cells, B cells, Langerhans cells	Not known
CD84	73	GR6	Monocytes, platelets, circulating B cells	Not known
CD85	110	GR4	Plasma cells, mantle-zone and germinal-center B cells, subpopulation of peripheral-blood NK cells	Possible role in T-cell activation in peripheral blood
