other fc receptor ( fcr ) -bearing lymphocytes , including natural killer ( nk ) cells , do not produce measurable lif activity when incubated with immune complexes ( additional evidence that the k and nk cells among ligands to the fcr of the appropriate lymphocytes , possibly without need for exogenous receptor bridging , is the only requirement for their activation to immune complex-induced lymphokine production ( iclp ) .
