Cell Markers
Macrophages
CD14, CD40 MHC II and B7 (they are APC's of course) Fc and C3b receptors
Natural killer cells
CD-16 (binds Fc of IgG) CD-56 (unique for NK cells)
T-reg cells
CD-3, CD-4 CD-25 (contain the alpha chain of IL-2 receptor)
T-helper Cells
CD-4+ CD-40ligand
Cytotoxic T-cells
CD-8+
What receptor protein binds LPS
CD-14 on Macrophages TCR on T-cells
All B-cells
Some kind of Ig (IgM and IgD on immature cells) CD-19 CD-20 CD-21 (EBV receptor) CD-40 (binds CD-40ligand on T-helpers) MHC II, B7
All T-cells
TCR (binds antigen MHC II complex) CD-3 (signal transduction with TCR) CD-28 (binds B7 on APC's)
