Neurological disorders associated with impaired gut microbiota

Proinflammatory mediators such as iNOS, ROS, COX2 and NF-B are released by microglia, resulting in neuroinflammation in Alzheimer’s disease. It is becoming more widely recognized as a symptom of Autism Spectrum Disorder. The establishment of gut-brain psychology is expected to have a significant impact on psychology and related disciplines. CLICK TO REVIEW

Supplementation of regular diet with medium-chain triglycerides for neuroprotective effects

This review summarizes currently available research on the effects and revealed mechanisms of using MCTs as a supplement to standard feed/diet without concomitant reduction of carbohydrate intake, highlighting open questions and potential considerations.

Investigating Causal Relations Between Circulating Metabolites and Alzheimer’s Diseases: a Mendelian Randomization Study

Our findings provided robust evidence supporting causal effects of circulating glycoprotein acetyls, ApoB, LDL cholesterol, and serum total cholesterol on higher risk of AD, whereas glutamine showed the protective effect. Further research is required to decipher the biological pathways underpinning associations. CLICK TO REVIEW

Role of microbiota-derived short-chain fatty acids in nervous system disorders

It has been noted remodeling in the gut microbiota metabolites associated with the pathophysiology of several neurological disorders, such as Alzheimer’s disease, multiple sclerosis, Parkinson’s disease, amyotrophic lateral sclerosis, stress, anxiety, depression, autism, vascular dementia, schizophrenia, stroke, and neuromyelitis optica spectrum disorders, among others. This review will discuss the current evidence from the most significant studies dealing with some SCFAs from gut microbial metabolism with selected neurological disorders. CLICK

Colonization of the Caenorhabditis elegans gut with human enteric bacterial pathogens leads to proteostasis disruption that is rescued by butyrate

Further experiments demonstrated that the beneficial effect of butyrate depended on the bacteria that colonized the gut and that this protective effect required SKN-1/Nrf2 and DAF-16/FOXO transcription factors. We also found that bacteria-derived protein aggregates contribute to the observed disruption of host proteostasis. Together, these results reveal the significance of enteric infection and gut dysbiosis

Improvement of colonic healing and surgical recovery with perioperative supplementation of inulin and galacto-oligosaccharides

Inulin and GOS diets were associated with increased butyrate production and better anastomotic healing. Histological analysis revealed an enhanced mucosal continuity, and this was associated with an increased re-epithelialization of the wound as determined by increased epithelial proliferation. Collagen concentration in peri-anastomotic tissue was higher with inulin and GOS diets and MMP activity, a marker

Centrally administered butyrate improves gut barrier function, visceral sensation and septic lethality in rats

Short chain fatty acids readily crosses the gut-blood and blood–brain barrier and acts centrally to influence neuronal signaling. We hypothesized that butyrate, a short-chain fatty acid produced by bacterial fermentation, in the central nervous system may play a role in the regulation of intestinal functions. Colonic permeability and visceral sensation was evaluated in rats. Septic

The microbiota-gut-brain axis and Alzheimer disease. From dysbiosis to neurodegeneration: focus on the central nervous system glial cells

Much evidence has accumulated over the past decade in favor of a significant association between dysbiosis, neuroinflammation and neurodegeneration. Presently, the pathogenetic mechanisms triggered by molecules produced by the altered microbiota, also responsible for the onset and evolution of Alzheimer Disease will be described. Our attention will be focused on the role of astrocytes and

Does modern research validate the ancient wisdom of gut flora and brain connection?

Both animal and human studies evaluating the role of gut dysbiosis on various neurological and neurosurgical diseases, published in peer-reviewed journals, were reviewed. Current studies do not provide conclusive evidence of a direct origin of CNS disorders from gut dysbiosis, but a possible modulatory role of gut microbiota in certain neurological disorders has been implicated.

Diet-Microbiota-Brain Axis in Alzheimer’s Disease

A strong association exists between lifestyle factors and AD prevalence wherein unhealthy dietary factors have been linked to neurodegeneration. Specific prudent dietary patterns might help in preventing or delaying AD progression by affecting β-amyloid production and tau processing and regulating AD-associated inflammation, metabolism and oxidative stress, plausibly via modulating gut microbiota.
