Short-chain fatty acid production by gut microbiota from children with obesity is linked to bacterial community composition and prebiotic choice

Z. C. Holmes, J. D. Silverman, H. K. Dressman, Z. Wei, E. P. Dallow, S. C. Armstrong, P. C. Seed, J. F. Rawls, L. A. David

This study examines SCFA production by gut microbiota from children with obesity in response to different prebiotics, finding significant inter-donor variation and donor-dependent effectiveness.

Conserved anti-inflammatory effects and sensing of butyrate in zebrafish

P. M. Cholan, A. Han, B. R. Woodie, A. R. Kurz, W. J. Britton, L. Ye, Z. C. Holmes, J. R. McCann, L. A. David, J. F. Rawls, S. H. Oehlers

The paper shows that butyrate, a short-chain fatty acid, has anti-inflammatory effects in zebrafish by reducing neutrophil and M1 macrophage recruitment to wounds, and identifies a conserved receptor for butyrate sensing in fish.
