taken together , the results indicate that the effector population responsible for antibody-induced killing belong to a subpopulation of cells that have the ability to spontaneously conjugate to the present target cells by virtue of naturally occuring undefined cell surface receptors designated nkr ( nk receptor ) and that the role of t-igg in the present system is similar to that of if .
