-The short chain fatty acids (SCFA) acetate, butyrate, and propionate, major metabolites derived from fermentation of dietary fibers by gut microbes, interact with multiple immune and metabolic pathways. The specific pathways that SCFA are thought to target, are dysregulated in cardiovascular disease, type II diabetes, and systemic inflammation. Most notably, these disorders are consistently linked to an attenuated lifespan in schizophrenia. ​ (({{pubmed>​long:​28396623}}))  ​(({{pubmed>​long:​000}}))+The short chain fatty acids (SCFA) acetate, butyrate, and propionate, major metabolites derived from fermentation of dietary fibers by gut microbes, interact with multiple immune and metabolic pathways.

In addition, in vitro studies reveal that free fatty acids in the intestine can have cytotoxic properties (Penn and Schmid-Schonbein,​ 2008). Therefore, there is still much to be learned about the compounds that modulate SCFA and the types and expression of the receptors that SCFA target. In addition, the role of SCFA in the brain and their relationship to neurobiological factors and pathways including neurotransmitter circuits, neurotrophic factors and other brain metabolites remains largely unknown.
