Affinity

Complementarity attraction

Avidity

Adhesion binding relationship (ABRS)

NK cells directly kill target cells by binding of the TLR on the NK cell surface with the target cell structure

NK cells only kill cells that are infected with viruses or obligate intracellular bacteria

NK cells directly kill target cells if they do not receive an inhibitory signal from the target cell

NK cells function by engagement of the NK-specific TCR on the NK cell surface
