Short Chain Fatty Acids News and Research

RSS

Butyrate and propionate are two important short-chain fatty acids (SCFAs) produced in the human gut. They have been shown to have significant immune system effects in the intestinal mucosa, by inducing the differentiation of T-regulatory cells via inhibition of histone deacetylase (HDAC). This enzyme keeps chromatin from unwinding and, therefore, inhibits gene transcription.
