Short-chain
fatty acids (SCFAs) are critical microbial metabolites. How does a decline in
SCFA levels link gut dysbiosis to systemic inflammation and liver injury?

Question

Accepted Answer

A
decrease in SCFAs impairs gut mucosal integrity, leading to a "leaky
gut" that permits translocation of lipopolysaccharide (LPS) into portal
circulation, activating resident hepatic Kupffer cells.

Answer

Intestinal
integrity is maintained entirely by Proteobacteria, with SCFAs having no
structural influence.

Answer

SCFAs
are toxic to the intestinal epithelium, and their reduction is protective
against systemic inflammation.

Answer

SCFAs
increase gut mucosal permeability, allowing dietary fats to enter systemic
circulation directly.
