Alkaline–Acid Intestine Environment Controlled by A Carbonic Anhydrase Gene Influences Synthesis of Sex Pheromone by Symbionts

open access: yesAdvanced Science, EarlyView.
A model proposing that elevated rectal expression of CAh1 in males alkalinizes the environment to regulate Bacillus production of a male‐specific sex pheromone. Abstract The intricate interplay between animals and their intestinal microbes is pivotal in shaping various aspects of animal biology.

Chronic PET‐Microplastic Exposure: Disruption of Gut–Liver Homeostasis and Risk of Hepatic Steatosis

open access: yesAdvanced Science, EarlyView.
Chronic exposure to environmentally relevant PET microplastics disrupts gut–liver homeostasis, leading to hepatic steatosis, early fibrosis, and altered gut microbiota. These effects signal metabolic imbalance and gut–liver axis impairment, emphasizing chronic microplastic ingestion as an emerging environmental health risk linked to non‐communicable ...

Structure‐Tailoring Cerium Nanozymes with Self‐Cascade ROS Scavenging Catalysis Modulate the Microbiota‐Gut‐Joint Axis for Rheumatoid Arthritis Therapy

open access: yesAdvanced Science, EarlyView.
A valence‐engineered CeOX nanozyme, with its Ce3+/Ce4+ ratio precisely controlled within the range of 0.27 to 0.93 through Au deposition, performs a self‐cascade oxidase‐superoxide dismutase‐peroxidase reaction, enabling continuous reactive oxygen species scavenging while minimizing oxygen generation.
