The neuropharmacology of butyrate: The bread and butter of the microbiota-gut-brain axis?

TL;DR: A critical review of the literature on butyrate and its effects on multiple aspects of host physiology with a focus on brain function and behaviour is provided and it is hypothesised that butyrates and other volatile SCFAs produced by microbes may be involved in regulating the impact of the microbiome on behaviour including social communication.
Journal ArticleDOI

The bowel and beyond: the enteric nervous system in neurological disorders

TL;DR: Evidence for ENS dysfunction is reviewed in the aetiopathogenesis of autism spectrum disorder, amyotrophic lateral sclerosis, transmissible spongiform encephalopathies, Parkinson disease and Alzheimer disease, and animal models suggest that common pathophysiological mechanisms account for the frequency of gastrointestinal comorbidity in these conditions.
Journal ArticleDOI

Altered gut microbiota and activity in a murine model of autism spectrum disorders.

TL;DR: Findings show that autism-like behaviour and its intestinal phenotype is associated with altered microbial colonization and activity in a murine model for ASD, with preponderance in male offspring, which open new avenues in the scientific trajectory of managing neurodevelopmental disorders by gut microbiome modulation.
Journal ArticleDOI

The valproic acid-induced rodent model of autism.

TL;DR: The VPA model provides a valuable tool to investigate the neurobiology underlying autistic behavior and to screen for novel therapeutics, highlighting its importance and reliability as an environmentally-induced animal model of autism.
Journal ArticleDOI

Annual Research Review: The role of the environment in the developmental psychopathology of autism spectrum condition.

TL;DR: Future investigations should consider the specificity of risks for ASC versus other atypical neurodevelopmental trajectories, timing of risk and protective mechanisms, animal model systems to study mechanisms underlying gene-environment interplay, and longitudinal studies to elucidate how rGE plays out over time.

Linking etiologies in humans and animal models: studies of autism

TL;DR: Rats with motor neuron deficits also had cerebellar anomalies like those reported in studies of autistic cases, supporting the idea that these animals may be a useful model of the developmental injury that initiates autism.
Journal ArticleDOI

A new neurobehavioral model of autism in mice: pre- and postnatal exposure to sodium valproate.

TL;DR: Mice exposed in utero to sodium valproate demonstrate behavioral and neuroanatomical abnormalities similar to those seen in autism, the neurodevelopmental effects of this antiepileptic agent were examined in mice following its pre- or postnatal administration.
Journal ArticleDOI

Epidemiological trends in rates of autism.

TL;DR: An update of a previous review of 23 surveys of autism and PDDs has identified 32 studies published in English language journals from 1966 to 2001 that followed a two-phase design for case identification, finding that large numbers of children just failed to meet criteria for autistic disorder.
Journal ArticleDOI

Autism spectrum disorders and epigenetics.

TL;DR: Data reviewed in this article highlight a variety of situations in which epigenetic dysregulation is associated with the development of ASD, thereby supporting a role for epigenetics in the multifactorial etiologies of ASD.
