Our findings uncovered the therapeutic effects of CBZ against disease pathogenesis in SOD1-G93A mice, indicating a promising clinical utilization of CBZ in ALS therapy.
AimsAlthough the pathophysiology of amyotrophic lateral sclerosis (ALS) is still not completely understood, the deregulated microglia polarization and neuroinflammation have been shown to contribute to the pathogenesis and progression of this disease. In the present study, we aimed to determine whether hirsutella sinensis (HS) could reduce neuroinflammatory and pathological changes in the spinal cord of SOD1G93A model mice of ALS and consequently ameliorate disease onset and progression.MethodsSOD1G93A mice were chronically treated with HS by gavage. Their lifespan was recorded, and motor behavior was evaluated by rotarod test. The pathological changes in skeletal muscles and motor neurons in spinal cords were assessed by immunofluorescent staining and hematoxylin‐eosin staining. The microglia activation and neuroinflammation were determined by immunofluorescent staining and RT‐PCR.ResultsOur data suggested that repeated HS administration prolonged the lifespan and extended disease duration of ALS mice without significant delay on disease onset. HS ameliorated the pathological changes in the motor neurons and gastrocnemius muscles. Moreover, HS promoted the transition of microglia from pro‐inflammatory M1 to anti‐inflammatory M2 phenotype in the spinal cord of ALS mice.ConclusionAll these findings indicate that HS may serve as a potential therapeutic candidate for the treatment of ALS.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
