Abstract
The effects of short-chain fatty acids (SCFA) produced by anaerobic bacteria, namely propionic, butyric and iso-butyric on T-cell proliferation was investigated. A dose-dependent inhibition of both phytohemagglutinin-induced blastogenesis and mixed lymphocyte culture was observed in the millimolar range of SCFA concentrations. The tested SCFA displayed different levels of suppression. The degree of activity was in the following order: butyrate greater than propionate greater than isobutyrate. T-cell inhibition was partially reversed, at least for propionic and isobutyric acids, by increasing the concentration of macrophages in the assay system. Furthermore, butyric acid displayed an interesting biphasic stimulation of monocyte interleukin-1 beta production, a cytokine with a powerful bone-resorbing activity. Since millimolar concentrations of SCFA are present in gingival fluid from periodontal pockets, the observed results support the role of these by-products of anaerobic metabolism in the pathogenesis of periodontal diseases.
