The Potential Role of Gut Peptide Hormones in Autism Spectrum Disorder

Xin-Rui Qi et al. Front Cell Neurosci. .

Abstract

Gut peptide hormones are one group of secretory factors produced from gastrointestinal endocrine cells with potent functions in modulating digestive functions. In recent decades, they have been found across different brain regions, many of which are involved in autism-related social, emotional and cognitive deficits. Clinical studies have revealed possible correlation between those hormones and autism spectrum disorder pathogenesis. In animal models, gut peptide hormones modulate neurodevelopment, synaptic transmission and neural plasticity, explaining their behavioral relevance. This review article will summarize major findings from both clinical and basic research showing the role of gut peptide hormones in mediating autism-related neurological functions, and their potential implications in autism pathogenesis. The pharmaceutical value of gut hormones in alleviating autism-associated behavioral syndromes will be discussed to provide new insights for future drug development.

Keywords: autism; cholecystokinin; ghrelin; gut peptide hormone; pituitary adenylate cyclase activating peptide; secretin; vasoactive intestinal peptide.
