Cell surface proteins
T cells
TCR (binds antigen-MHC complex) CD3 (associated with TCR for signal 
transduction) CD28 (binds B7 on APC)
Helper T cells
CD4, CD40L, CXCR4/CCR5 (co-receptors for HIV)
Cytotoxic T cells
CD8
Regulatory T cells
CD4, CD25
B cells
 Ig (binds antigen)
CD19, CD20, CD21 (receptor for Epstein-Barr virus), CD40 MHC II, B7
Macrophages
CD14 (receptor for PAMPs, eg, LPS), CD40 CCR5 MHC II, B7 (CD80/86)
Fc and C3b receptors (enhanced phagocytosis)
NK cells
CD16 (binds Fc of IgG), CD56 (suggestive marker for NK)
Hematopoietic stem cells
CD34
