Parkinson’s disease (PD) is a neurodegenerative disease characterized by α-synucleinopathy, which involves all districts of the brain-gut axis, including the central, autonomic and enteric nervous systems. Previous findings suggest that the intestinal microbiome is altered in PD and is related to motor phenotype. However how dysbiosis arises and whether this feature contributes to PD pathogenesis remains unknown. The aim was to evaluate gut microbiome and the serum cytokine profile in PD. We quantified serum interleukin (IL) levels (IL-1β, IL-6, IL-10, TNF-α, IFN-γ) in 55 PD patients. Study of the fecal samples was performed by real time PCR method and bacteriologically. Discovered the relationship between the intensity of dysbiosis and the level of proinflammatory cytokine IFN-γ, IL-6.We show that disturbances in plasma cytokine level could be more profound in PD patients with altered composition of intestinal microbiota, which may explain the mechanism of influence of microbiota composition on the PD manifestations.
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.
