The protective effect of Wnt3a on inflammatory response in oxygen-glucose deprivation/reoxygenation (OGD/R) astrocyte model.
Involving in the immune response after cerebral infarction, astrocytes could secrete large amounts of pro- and anti-inflammatory factors. The aim of this study is to investigate the effect of Wnt3a intervention on the inflammatory response of oxygen-glucose deprivation (OGD) followed by reoxygenation (OGD/R) astrocyte model, and to provide a new target for immunoprotective treatment of cerebral infarction. We constructed the OGD/R rat astrocyte model, the astrocytes were treated by different concentrations of glucose (25, 50, 100 mM) intervened with/without Wnt3a (25 µg/ml). Microscope was used to observe the cell survival in rat astrocytes. The relative expression of inflammatory factors (TNF-a, IL-6, HIF-a) in rat astrocytes was detected by qRT-PCR. The expression of inflammatory factors such as TNF-a, IL-6 and HIF-a in rat astrocytes was increased after OGD/R treatment. The Wnt3a intervention promoted cell survival and decreased the expression of inflammatory factors in rat astrocytes induced by OGD/R. There is a neuroprotective effect that Wnt3a intervention could reduce inflammatory response in the OGD/R rat astrocyte model.
期刊介绍：
Folia Neuropathologica is an official journal of the Mossakowski Medical Research Centre Polish Academy of Sciences and the Polish Association of Neuropathologists. The journal publishes original articles and reviews that deal with all aspects of clinical and experimental neuropathology and related fields of neuroscience research. The scope of journal includes surgical and experimental pathomorphology, ultrastructure, immunohistochemistry, biochemistry and molecular biology of the nervous tissue. Papers on surgical neuropathology and neuroimaging are also welcome. The reports in other fields relevant to the understanding of human neuropathology might be considered.
