The Natural Product Corramycin Acts as a DNA Gyrase Poison and Overcomes Fluoroquinolone Resistance in Mycobacterium tuberculosis

open access: yesAdvanced Science, EarlyView.
Corramycin, a myxobacterial natural product antibiotic, exhibits potent bactericidal activity against multidrug‐resistant Mycobacterium tuberculosis. The compound hijacks bacterial transporters such as BacA and OppABCD to enter the cell and inhibits DNA synthesis through a previously unrecognized mode of DNA gyrase poisoning, locking the enzyme in an ...

Tumor‐Derived Exosomal circAP2B1 Induces M2 Macrophage Polarization by Enhancing Mitochondrial Homeostasis to Promote Esophageal Squamous Cell Carcinoma Progression

open access: yesAdvanced Science, EarlyView.
ESCC‐derived exosomal circAP2B1 promotes tumor progression by reprogramming mitochondrial metabolism via the ESRRA/KPNA1/MFN2 axis to induce M2 polarization of macrophages. ABSTRACT Esophageal squamous cell carcinoma (ESCC) remodels the immunosuppressive tumor microenvironment via exosome‐mediated intercellular communication.

METTL7A Downregulation Drives SLC1A5‐Mediated Glutamine Competition to Promote Tumor Proliferation and Suppress CD8+ T Cell Immunity in Gastric Cancer

open access: yesAdvanced Science, EarlyView.
GC cells enhance glutamine accumulation by upregulating SLC1A5 expression. This upregulation not only boosts GC cell proliferation, but also outcompetes CD8+ T cells for glutamine and suppresses their antitumor immunity. Mechanistically, METTL7A deficiency in GC induces SLC1A5 overexpression via an m6A‐dependent pathway and N‐glycosylation ...

Generation of Nasal Cell‐Derived Human Alveolar Organoids and Organoid‐Macrophage Assembloids for in Vitro Lung Modeling

open access: yesAdvanced Science, EarlyView.
This study demonstrates the generation of human alveolar organoids from nasal cells, which, when co‐cultured with monocyte‐derived macrophages, promotes maturation of both components and forms alveolar assembloids resembling native alveoli. These alveolar organoids and assembloids offer accessible, physiologically relevant in vitro systems for ...

Entorhinal Astrocyte Transplants Restore Spatial Exploration and Alleviate Amyloid‐Beta Pathology in Alzheimer's Mice

open access: yesAdvanced Science, EarlyView.
Impaired MEC astrocytic Ca2+ signaling is associated with fragmented spatial exploration in AD mice. Region‐specific glial progenitor transplantation generates engrafted astrocytes that are accompanied by improved AQP4 polarization, reduced amyloid‐β‐associated pathology, attenuated neuroinflammation, preserved synaptic integrity, and ameliorated ...

Application and Single‐Cell Regulation Mechanism of Engineered EVs Combined With 4D‐Printed Hydrogel for Infected Burn Repair

open access: yesAdvanced Science, EarlyView.
4D bioprinted hydrogel loaded with FGF2‐modified extracellular vesicles (4D@F‐EVs) targets dermal fibroblasts and elevates local wound FGF2 levels via sustained release of F‐EVs. It activates PI3K‐Akt signaling, restores critical KGF+ fibroblast–KGFR+ keratinocyte crosstalk, enhances robust angiogenesis and collagen deposition to efficiently repair ...
