The interplay between immunity, the nervous system, and microbiota
By Dr. Priyom Bose, Ph.D. Aug 15 2023 Reviewed by Benedette Cuffari, M.Sc. A recent Immunity review analyzes the influence of the gut microbiota on neural and immune networks. Understanding the association between these seemingly isolated entities could contribute to the development of novel therapies and interventions. Study: Boundaries and integration between microbiota, the nervous system, and immunity....

Early signals of Parkinson’s found in gut microbiota of REM sleep behavior disorder patients
by Justin Jackson , Medical Xpress Shifted microbial composition across the prodromal and early stages of α-synucleinopathy. a Principal coordinates analysis (PCoA) of microbial communities across control (n = 108), RBD-FDR (n = 127), RBD (n = 170), and early PD (n = 36) based on Bray–Curtis distance matrix at the genus level. The label of each group indicates group centroid. Boxplots along...
