Fatty acids are good energy sources (9 kcal per gram) that aerobic tissues can use except for the brain (glucose is an alternative source). Apart from source, fatty necessary cell signaling, learning-related memory, modulating gene expression, and functioning as cytokine precursors. Short-chain (SCFAs) saturated arranged a straight chain consisting minimum of 6 carbon atoms. SCFAs possess various beneficial effects like improving metabolic function, inhibiting insulin resistance, ameliorating immune dysfunction. In this review, we discussed biogenesis, absorption, transport SCFA. act signaling molecules by stimulating G protein-coupled receptors (GPCRs) suppressing histone deacetylases (HDACs). The role SCFA on glucose metabolism, acid its effect system also reviewed with updated details. anticancer, anti-diabetic, hepatoprotective effects. Additionally, association protective against brain-related diseases, kidney cardiovascular damage, inflammatory bowel diseases were reviewed.

Autism spectrum disorders (ASD) are serious, highly variable neurodevelopmental disorders, commonly characterized by the manifestation of specific behavioral abnormalities, such as stereotypic behaviors and deficits in social skills, including communication. Although neurobiological basis for ASD has attracted attention recent decades, role microglial cells, which main resident myeloid cell population brain, is still controversial underexplored. Microglia play several fundamental roles orchestrating brain development homeostasis. As such, alterations intrinsic functions these cells could be one driving forces responsible various ASD. sensitive to environmental cues. Amongst factors known influence their functions, gut microbiota emerged a central player, controlling both maturation activation. Strikingly, there now compelling data suggesting that intestinal can causative behavioural changes associated with Not only dysbiosis reported patients, but therapies targeting microbiome markedly alleviate symptoms. Here we explore emerging mechanisms altered contribute major etiological We then demonstrate how pre- postnatal stimuli modulate phenotype function, underpinning notion reciprocal interactions between microglia microbes crucial aetiology.
