High-fat diet disrupts gut immune protein and microbial daily rhythms linked to metabolism problems

AI simplified

Abstract

High-fat diet impairs host metabolic homeostasis, resulting in arrhythmic host Reg3γ expression.

  • Gut microbial rhythms are influenced by diet and host factors.
  • The host antimicrobial peptide Reg3γ interacts with key ileal microbes.
  • There is no correlation between Reg3γ expression and the intestinal core circadian clock.
  • Dietary influences disrupt the oscillation of gut microbes and host metabolism.
  • Restoring gut microbial sensing of dietary signals may help improve metabolic dysfunction.
