Abstract
PURPOSE OF REVIEW: The purpose of this review is to summarize the evidence supporting a role of short-chain fatty acids (SCFAs) as messengers facilitating cross talk between the host and gut microbiota and discuss the effects of altered SCFA signaling in obesity and hypertension. RECENT FINDINGS: Recent evidence suggests there to be a significant contribution of gut microbiota-derived SCFAs to microbe:host communication and host metabolism. SCFA production within the intestine modulates intestinal pH, microbial composition, and intestinal barrier integrity. SCFA signaling through host receptors, such as PPARγ and GPCRs, modulates host health and disease physiology. Alterations in SCFA signaling and downstream effects on inflammation are implicated in the development of obesity and hypertension. SCFAs are crucial components of the holobiont relationship; in the proper environment, they support normal gut, immune, and metabolic function. Dysregulation of microbial SCFA signaling affects downstream host metabolism, with implications in obesity and hypertension.
