Autoantibodies against Central Nervous System Antigens and the Serum Levels of IL-32 in Patients with Schizophrenia.
Background: Schizophrenia is a disease of the nervous system, and immune system disorders can affect its pathogenesis. Activation of microglia, proinflammatory cytokines, disruption of the blood-brain barrier due to inflammation, activation of autoreactive B cells, and consequently the production of autoantibodies against system antigens are among the immune processes involved in neurological diseases. Interleukin-32 (IL-32) is a proinflammatory cytokine that is essential in activating innate and adaptive immune responses. This study aimed to measure the serum level of IL-32 as well as the frequency of autoantibody positivity against several nervous system antigens in patients with schizophrenia.
Material and methods: This study was conducted on 40 patients with schizophrenia and 40 healthy individuals in the control group. Serum IL-32 levels were measured by ELISA. The frequency of autoantibodies against Hu, Ri, Yo, Tr, CV2, amphiphysin, SOX1, Zic4, ITPR1, CARP, glutamic acid decarboxylase GAD, recoverin, titin, and ganglioside antigens was measured by the indirect immunofluorescence method.
Results: Serum IL-32 levels in patients with schizophrenia were significantly higher compared to the control group. The frequency of autoantibodies against GAD and RI antigens in patients with schizophrenia was significantly higher than in the control group. Autoantibodies were positive in 8 patients for GAD antigen and 5 patients for RI antigen. Autoantibodies were also positive in 2 patients for CV2, 1 patient for Hu, and 1 patient for CARP. Negative results were reported for other antigens.
Conclusion: Our findings suggest that elevated the serum IL-32 level and autoantibodies against GAD and RI antigens may be a reflection of immune system dysregulation in patients with schizophrenia.
期刊介绍：
The rapidly expanding area of research known as neuroimmunomodulation explores the way in which the nervous system interacts with the immune system via neural, hormonal, and paracrine actions. Encompassing both basic and clinical research, ''Neuroimmunomodulation'' reports on all aspects of these interactions. Basic investigations consider all neural and humoral networks from molecular genetics through cell regulation to integrative systems of the body. The journal also aims to clarify the basic mechanisms involved in the pathogenesis of the CNS pathology in AIDS patients and in various neurodegenerative diseases. Although primarily devoted to research articles, timely reviews are published on a regular basis.
