>Thus, the target specificity of NK cells is greater than that 
for CTLs.

Actually, NK cells have less specificity, they recognize all 
kinds of things.  They seem to be predominate in immune 
surveillance, i.e. they clean up random cancer cells before they 
get out of control.  They also seem to have some regulatory 
functions over their kindred T cells, perhaps maintaining the 
balance between "normal" immunity and autoimmunity from a 
hyperactive T cell stimulation.
