Production of interferon (IFN)-alpha and -gamma by leukocytes from 34 patients with acute schizophrenia and 34 controls was measured before and after 5-6 weeks of antipsychotic treatment by using Sendai virus as IFN-alpha inducer and lentil lectin as inducer for IFN-gamma production. The schizophrenia series included 13 first admission patients (mean duration of illness 1.1 years) and 21 re-entry patients (mean duration of illness 10.1 years). Of the total series 23 were drug-free at the time of pretreatment sampling. In all subgroups the schizophrenic patients produced less IFNs than healthy controls although the differences reached statistical significance only in the total group of schizophrenic patients with regard to production of IFN-alpha. The antipsychotic drug treatment did not have an effect on IFN production. The techniques used, the influence of genetic factors, and eventual clinical implications are discussed.

UI MeSH Term Description Entries
D007108 Immune Tolerance The specific failure of a normally responsive individual to make an immune response to a known antigen. It results from previous contact with the antigen by an immunologically immature individual (fetus or neonate) or by an adult exposed to extreme high-dose or low-dose antigen, or by exposure to radiation, antimetabolites, antilymphocytic serum, etc. Immunosuppression (Physiology),Immunosuppressions (Physiology),Tolerance, Immune
D007370 Interferon Type I Interferon secreted by leukocytes, fibroblasts, or lymphoblasts in response to viruses or interferon inducers other than mitogens, antigens, or allo-antigens. They include alpha- and beta-interferons (INTERFERON-ALPHA and INTERFERON-BETA). Interferons Type I,Type I Interferon,Type I Interferons,Interferon, Type I,Interferons, Type I
D007371 Interferon-gamma The major interferon produced by mitogenically or antigenically stimulated LYMPHOCYTES. It is structurally different from TYPE I INTERFERON and its major activity is immunoregulation. It has been implicated in the expression of CLASS II HISTOCOMPATIBILITY ANTIGENS in cells that do not normally produce them, leading to AUTOIMMUNE DISEASES.

D007962 Leukocytes White blood cells. These include granular leukocytes (BASOPHILS; EOSINOPHILS; and NEUTROPHILS) as well as non-granular leukocytes (LYMPHOCYTES and MONOCYTES).
