Hepatitis E Virus ORF1 Polyprotein Harbors a Pocket‐Like Cavity That Is Vital for Virus Replication and Represents a Novel Antiviral Target

open access: yesAdvanced Science, EarlyView.
Within the hepatitis E virus (HEV) ORF1 polyprotein, the X domain interacts with viral RNA‐dependent RNA polymerase (RdRp), forming a functional “pocket‐like” cavity (PC) that is crucial for viral replication. Structure‐based screening, surface plasmon resonance (SPR) assays, and HEV model validation collectively identify saikosaponin D and ...

Single‐Cell Transcriptomics Unravels Growth Factor Erv1‐Like Mediated Ferroptosis as a Key Driver of Intestinal Epithelial Dysfunction in Ulcerative Colitis

open access: yesAdvanced Science, EarlyView.
Single‐cell transcriptomic profiling of ulcerative colitis (UC) tissues identified downregulation of GFER in intestinal epithelial cells. Mechanistically, GFER interacts with PCBP1 to help maintain intracellular iron homeostasis and may also reduce lipid peroxidation by activating the PGC‐1α/PPARγ signaling pathway, thereby inhibiting ferroptosis ...

PVC Nanoplastics Exposure Exacerbates Asthma through R‐Loop Accumulation and Subsequent STING Activation in Macrophages

open access: yesAdvanced Science, EarlyView.
Polyvinyl chloride (PVC) nanoplastics (NPs) are shown to aggravate allergic airway inflammation in asthma by triggering R‐loop accumulation and activating the cGAS‐STING pathway in macrophages. This study reveals a novel immunotoxic mechanism linking environmental plastic exposure to asthma pathogenesis and highlights potential molecular targets for ...

Calhm6 Governs Macrophage Polarization Through Chp1‐Camk4‐Creb1 Axis and Ectosomal Delivery in Inflammatory Responses

open access: yesAdvanced Science, EarlyView.
Calhm6 drives M2 macrophage polarization via the Chp1‐Camk4‐Creb1 axis, suppressing inflammation through calcium‐dependent ectosomal delivery. Calhm6 deficiency enhances M1 responses, boosting bactericidal activity but exacerbating tissue damage. LPS/IFNγ upregulate Calhm6 via Irf1, while IL‐4/Stat6 inhibits it, balancing immune outcomes.

Polyhalogenated Carbazole Impairs Dopaminergic Neurons through Dysregulation of Liquid–Liquid Phase Separation in Caenorhabditis elegans

open access: yesAdvanced Science, EarlyView.
Polyhalogenated carbazoles (PHCZ), persistent environmental contaminants, preferentially accumulate in neuronal tissues. Studies using Caenorhabditis elegans and human neuronal cell lines reveal that PHCZ induce dopaminergic neurodegeneration by promoting liquid–liquid phase separation of α‐synuclein, reducing condensate fluidity, impairing ...

Single‐Cell Transcriptome Analysis Reveals That Hmga2 Regulates Neuroinflammation and Retinal Function by Modulating Müller Cell Autophagy Through PI3K/AKT Signaling Following MCAO‐Induced Retinal Ischemia

open access: yesAdvanced Science, EarlyView.
Employing snRNA‐seq post‐MCAO‐induced retinal ischemia (RI), this study revealed a novel Hmga2‐high Müller cell subpopulation. Hmga2 knockout alleviated neuroinflammation and RI symptoms, potentially by binding PI3K and regulating Müller cell autophagy.
