Abstract: Background: Schizophrenia is a heterogeneous mental disorder with a variety of symptoms. Although, there are no pathognomonic abnormalities in brains of schizophrenia patients, recent years have witnessed research progresses in revealing pathologic changes in cellular and molecular levels. Objective: This article reviewed recent human studies showing neuroimmune alterations in schizophrenia patients and offered explanations for roles of neuroinflammation in the pathogenesis of schizophrenia by citing some of experimental data from non-human studies. The focus of this review was put on pharmacological and therapeutic evidence pointing to a recommendation of anti-inflammatory treatment for patients with schizophrenia. Particularly, it provided compelling evidence supporting an anti-inflammatory effect of antipsychotics by reviewing a relatively large body of studies in the categories of in vitro, animals and humans. Conclusion: Then, it reviewed recent clinical trials with minocycline, a second-generation tetracycline, or the selective COX-2 inhibitor celecoxib. Most of these clinical trials provided promising results of superior beneficial treatment effects as the consequence of co-administration of standard antipsychotic drugs and anti-inflammatory compounds, compared with antipsychotic drugs alone.
