title: T-cell subsets in acute psychotic schizophrenic patients.
abstract: Two-color flow cytometric analysis was performed on peripheral blood lymphocytes of 16 untreated schizophrenic patients during an acute psychotic attack and 16 healthy control subjects to evaluate differences in T-cell subpopulations. In schizophrenic patients, we observed decrease in CD4+ 2H4+ (suppressor-inducer) and CD8+ 2H4+ (suppressor-effector) T-cell subsets. The selective loss of 2H4+ cell markers both on helper and suppressor T cells was not correlated to the severity of the acute psychosis. Our results may indicate a mechanism of an immune disequilibrium in schizophrenic patients during an acute psychotic attack.
