[The function of lytic effector cells in schizophrenic patients]

The present study aimed at elucidating lytic effector cell function in 32 schizophrenic patients and comparing the results with data obtained in 27 normal probands. Natural killer cell (NK) activity and antibody dependent cellular cytotoxicity (ADCC) were tested. Schizophrenics did not differ from normal controls in either test system. Within the schizophrenic group, higher NK activity was detected in patients with neuroleptic monotherapy (p less than 0.05). Patients given a combination of neuroleptics, antidepressants and/or lithium did not differ from drug-free patients in either test system. There was no influence of psychopathological variables on lytic effector cell function.
