Objective: Immune system abnormalities in schizophrenia have been previously studied. According to the present point of view, an infection or autoimmune process might be occurring in the form of cellular and/or humoral immune system abnormalities in schizophrenia. Furthermore, several effects of antipsychotic medication on the immunological profile of schizophrenic patients have been demonstrated. The present study aimed to compare the total T-lymphocytes level and the T-lymphocyte subset ratios in schizophrenia patients not treated with antipsychotics and healthy controls. The relationship between disease duration, symptom severity, and treatment response and T-lymphocyte profiles were investigated.
