dsRADAR: Imaging and Detecting Cellular dsRNA by Repurposing RNA‐Binding Proteins

Angewandte Chemie, EarlyView.
Double‐stranded RNA (dsRNA) plays an important role in the innate immune system, but can be misregulated in disease, leading to inflammation. Despite the importance of this motif, methods for detecting dsRNA remain limited. This work shows that ADAR3 can be repurposed to provide improved detection of dsRNA, which is demonstrated in the context of viral

Deep Learning‐Driven Discovery and Engineering of an Efficient PETase for Depolymerization and Detoxification of PET Microplastics Under Physiological Conditions

Advanced Science, EarlyView.
A deep learning–driven pipeline mining 246 million protein sequences uncovers AhPETase, an evolutionarily distinct PET hydrolase. Engineered variant AhPETaseM1 degrades post‐consumer PET microplastics under physiological conditions and reverses microplasticinduced cytotoxicity in human lung and colon cells, establishing enzymatic microplastic ...

Enteric ChAT‐Expressing Neurons Mediate the Protective Effect of Lactobacillus plantarum in Inflammatory Bowel Disease

Advanced Science, EarlyView.
In colitis patients and mice, reduced Lactobacillus abundance is observed. Experimental studies show that L. plantarum A736 metabolizes dietary tryptophan into indole‐3‐lactic acid (ILA), while both L. plantarum A736 and ILA impact ChAT‐expressing enteric neurons and acetylcholine levels, thereby regulating intestinal immune responses and alleviating ...

Multifunctional Zinc Glycyrrhizinate‐Integrated Gel for Enhanced Probiotic Delivery and Alleviation of Acute and Spontaneous Colitis

Advanced Science, EarlyView.
Multifunctional oral delivery system—L. reuteri@ZGM—act as both a carrier and therapeutic adjuvant, providing ROS scavenging, and mucin‐interactive properties tailored to the IBD microenvironment. This bioactive gel safeguards L. reuteri from gastric degradation, enhances mucosal adhesion, and promotes long‐term retention at inflamed sites, thereby ...

Adhesion‐Enhanced Engineered Probiotic for Prolonged Intestinal Retention and Calprotectin‐Responsive IBD Therapy

Advanced Science, EarlyView.
An intelligent engineered probiotic platform is developed for the precision management of inflammatory bowel disease. By integrating surface‐displayed adhesins with an inflammation‐responsive CAT‐SOD‐GPx tripartite fusion system and mucosal repair factors, this programmable system achieves prolonged intestinal retention and multi‐pronged therapy.

Assembled Hyaluronic Acid Therapeutics for Targeting M1 Macrophages and Regulating Immune Homeostasis for Ulcerative Colitis Treatment

Advanced Science, EarlyView.
An orally administered, drug‐free hyaluronic acid nanoassembly, uhNAs‐OA, accumulates in the inflamed colon and is preferentially internalized by M1‐like macrophages via HA‐CD44 interactions. uhNAs‐OA scavenges excess ROS, suppresses NF‐κB signaling and remodels the colonic immune landscape, resulting in robust therapeutic efficacy in acute, chronic ...

A Postbiotic‐Inducing Ganoderma applanatum Polysaccharide Repairs the Intestinal Barrier via a Phocaeicola vulgatus ‐ Tridecylic Acid Axis

Advanced Science, EarlyView.
This study identifies GAP2, a bioactive polysaccharide fraction derived from Ganoderma applanatum, as a postbiotic inducer that repairs intestinal barrier damage in a gut microbiota‐dependent manner. GAP2 enriches Phocaeicola vulgatus, which degrades GAP2 and promotes tridecylic acid production, triggering Rho/CDC42 signaling and tight‐junction ...
