| Abstract: | Bovine blood lymphocytes showed a high antibody-dependent (AD) cytotoxicity against target cultured L cells. The cytological analysis of immune cellular complexes, formed by affector lymphocytes with target cells during the cytotoxic reaction in vitro, revealed that adsorption of AD lymphocytes to target cells was completed within the first hours of incubation. Temporal parameters of contact between effector and target cells and dissociation of adsorbed lymphocytes varied widely, but after 48 hours of incubation the number of immune cellular complexes decreased by 5.6%. The morphological modification of AD effector lymphocytes during interaction with target cells is described. |
