Study finds gut microbiota influence severity of respiratory viral infection
Peer-Reviewed Publication GEORGIA STATE UNIVERSITY THIS PICTURE ILLUSTRATES AN EXAMPLE OF GUT MICROBIOTA COMPOSITION DICTATING HOW RESIDENT LUNG ALVEOLAR MACROPHAGES (AM) RESPOND TO VIRAL INFECTION. THE PRESENCE OF SEGMENTED FILAMENTOUS BACTERIA, A COMMENSAL MICROBE PRESENT IN SOME MICE, REPROGRAMS AM GENE EXPRESSION, INCREASING COMPLEMENT EXPRESSION AND PHAGOCYTOSIS, THEREBY ENABLING AM TO ENGULF AND DESTROY VIRAL...
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...
New evidence hints at the role of gut microbiota in autistic spectrum disorder
by Ingrid Fadelli , Medical Xpress Credit: CC0 Public Domain Autism spectrum disorder (ASD) is a neurological and developmental condition that affects how humans communicate, learn new things and behave. Symptoms of ASD can include difficulties in interacting with others and adapting to changes in routine, repetitive behaviors, irritability and restricted or fixated interests for...
