An artificial mucus-integrated in vitro model enables stable live probiotic–host co-culture and recapitulates dynamic hBD-2-mediated antimicrobial feedback

Gut Microbes Reports
In vitro models for host–microbe interaction often have limited physiological relevance due to the absence of a protective mucus layer, reliance on non-viable bacteria, and short co-culture durations. Here, we present the first scalable and biocompatible

Calcium-activated Chloride Channel Regulator 1 (CLCA1) Controls Mucus Expansion in Colon by Proteolytic Activity

EBioMedicine, 2018
Many epithelial surfaces of the body are covered with protective mucus, and disrupted mucus homeostasis is coupled to diseases such as ulcerative colitis, helminth infection, cystic fibrosis, and chronic obstructive lung disease. However, little is known

Hollow Cu2O Nanozymes Enhance Probiotic Therapy for Colitis via Redox Homeostasis and TXNIP/NLRP3 Inflammasome Inhibition

Advanced Science, EarlyView.
Hollow cuprous oxide (H‐Cu2O) nanozymes feature enlarged catalytic surfaces for superior reactive oxygen species (ROS) scavenging. By efficiently neutralizing mucosal ROS, H‐Cu2O directly suppresses the TXNIP/NLRP3 inflammasome axis and restores intestinal epithelial barrier integrity.

Disrupting Helicobacter pylori Iron Homeostasis With Bismuth Nanodrug‐Mediated Nutritional Trap for Targeted Gastric Infection Therapy

Advanced Science, EarlyView.
A “nutritional trap” strategy centered on disrupting bacterial iron homeostasis is proposed. The synthesized Bi‐TP@FU (TBF) can target Helicobacter pylori, interfere with the bacterial iron uptake and utilization processes to disrupt its iron homeostasis, induce bacterial death, and meanwhile preserve the balance of the intestinal flora.

Novel Roles for Chloride Channels, Exchangers, and Regulators in Chronic Inflammatory Airway Diseases

Mediators of Inflammation, 2015
Chloride transport proteins play critical roles in inflammatory airway diseases, contributing to the detrimental aspects of mucus overproduction, mucus secretion, and airway constriction.

Subversion of Atypical Mucin Traps by a Spore‐Coat Effector Blocks Cellular Immunity in Drosophila

Advanced Science, EarlyView.
While the entomopathogenic fungus Metarhizium robertsii can evade insect humoral immunity, its subversion of cellular defenses is still elusive. We identify Eac1 as a spore‐coat protein essential for infecting drosophilids by targeting atypical mucins (Sgf1 and Sgf2), which can entrap spores in a gel matrix and thereby facilitate hemocyte encapsulation.

TGF-β3 Promotes MUC5AC Hyper-Expression by Modulating Autophagy Pathway in Airway EpitheliumResearch in context

EBioMedicine, 2018
Mucus secretion accumulation in the airways may act as a contributing factor for the development of airflow limitation in severe fetal asthma patients. Accumulated evidences showed that transforming growth factor beta (TGF-β) plays a regulatory role in ...

Overcoming Transmission Barriers: A Dual‐Functional Adhesive Hydrogel for Direct Monkeypox Virus Neutralization and Wound Healing

Advanced Science, EarlyView.
MPXV infection leads to persistent viral replication and severe local inflammation, while existing treatments cannot simultaneously remove viruses and repair injured tissue. This study constructs Polymer@mPDA@Gel hydrogel via a two‐step hierarchical assembly method: mPDA anchors photothermal polymers to form antiviral photothermal subunits, which are ...

Single‐Cell Transcriptomics and Metabolomics Reveal Glutamate Dehydrogenase as a Central Regulator of Nitrogen Metabolic Remodeling During Alkalinity Adaptation in Crustaceans

Advanced Science, EarlyView.
Single‐cell transcriptomics reveals the cellular response of Macrobrachium hainanense to carbonate alkalinity stress. Alkalinity stress impairs branchial ammonia excretion, induces mitochondrial dysfunction, and drives cell‐type‐specific changes in gills and hemocytes.
