Gut bacteria break down dietary fiber into short-chain fatty acids, which are known to affect our immune system. In this study, researchers investigated in detail the mechanisms by which these compounds mediate the activation of mast cells.

Gut bacteria can process dietary fiber into an anti-allergy weapon

This picture illustrates an example of gut microbiota composition dictating how resident lung alveolar macrophages (AM) respond to viral infection. The presence of segmented filamentous bacteria, a commensal microbe present in some mice, reprograms AM gene expression, increasing complement expression and phagocytosis, thereby enabling AM to engulf and destroy viral pathogens without inflammatory signaling.
