why not CD16?

  #4

CD 16 is Fc receptor on NK cells, so to activate NK you need Ig. And you can find it on macrophages and mast cells too. Compare to CD 56 which represents NK ( you can see it only here). And as you know Babesia attacks RBCells, is an intracellular parasite, which lack MHC 1 , so can not be lysed Tc.

very nice explanation..
one more thought, as NK cells identify cells without MHC-I, how do RBC's normally stay protected from the action of NK cells?
