[Neuromediator mechanisms of regulating immune reactions in schizophrenics].

Eighty patients with paranoid schizophrenia were studied for the cell-mediated (T lymphocytes) and humoral (B lymphocytes, immunoglobins A, M and G) immunity. Using stimulants and blockers of dopaminergic (L-DOPA, haloperidol), serotoninergic (reserpine, deseril), cholinergic (galanthamine, benactyzin) and GABA-ergic (lithium hydroxybutyrate, isoniazid) systems, the authors have established that the dopaminergic system intensifies the immune response while serotoninergic, cholinergic and GABA-ergic systems inhibit it. It is postulated that the effect of neuromediatory systems on the immune responses is reciprocal.
