Zinc‐Coordinated Trienzyme Nanogel Cascade Therapy for Accelerated Post‐Pancreatectomy Cutaneous Wound Healing

Advanced Materials, EarlyView.
A zinc‐coordinated nanogel assembly is reported that co‐delivers three enzymes to regulate glucose, oxidative stress, and oxygen levels. This system mimics natural enzyme cascades to reprogram the wound environment after pancreatectomy. In a post‐pancreatectomy mouse model, it accelerates healing by reducing infection, promoting blood vessel growth ...

HERV‐K TM Subunit Elicits CD8+ T Cell Anergy and Tumor Immune Evasion via Targeting CD3 Coreceptor ε in AML and PDAC

Advanced Science, EarlyView.
Novel viral immune checkpoint K‐TM subunit is aberrantly expressed in CD8+ T cells and enriched in sera of cancer patients, inducing CD8+ T cell anergy and eliciting potent tumor immune escape in mouse model. Mechanistically, K‐TM directly targets and induces the phosphorylation of CD3ε receptor.

Single Cell and Spatial Transcriptomics Define a Proinflammatory and Profibrotic Niche After Kidney Injury

Advanced Science, EarlyView.
By integrating single‐cell RNA sequencing and spatial transcriptomics, tenascin C (TNC) is unveiled as a central organizer of the proinflammatory and profibrotic niche in kidney fibrosis. TNC promotes macrophage activation through TLR4/NF‐κB signaling, leading to renal inflammation and fibrosis.

Synthesis and Isolation of Diastereomeric Anomeric Sulfoxides from a d-Mannuronate Thioglycoside Building Block

Molbank, 2020
Methyl [S-phenyl 4-O-acetyl-2,3-di-O-benzyl-1-thio-α-d-mannopyranoside (R/S)S-oxide] uronate was synthesised from a thioglycoside mannosyl uronate donor in a 98% yield.

Mechanical Cues Regulate Cargo Sorting and Export at the Golgi

Advanced Science, EarlyView.
A pathway is identified linking extracellular matrix stiffness to secretion via Src–FAK–AMPK–GBF1 signaling. Golgi‐localized GBF1 acts as a mechanotransducer whose phosphorylation controls post‐Golgi cargo sorting toward secretion or lysosomal degradation.

PPP1R3B Suppresses Atherosclerosis by Promoting the M2 Polarization of Macrophages Through Glycogen Metabolic Reprogramming

Advanced Science, EarlyView.
PPP1R3B induces anti‐inflammatory M2 macrophage polarization and maintains energy supply in plaques. Its absence accelerates plaque progression. PPP1R3B regulates M2 macrophage polarization and energy metabolism via phosphorylated STAT3 (p‐STAT3), which plays a dual role by activating anti‐inflammatory transcriptional programs through the PPAR‐γ/PGC‐1α/

Conductive Microneedles Loaded With Polyphenol‐Engineered Exosomes Reshape Diabetic Neurovascular Niches for Chronic Wound Healing

Advanced Science, EarlyView.
This study establishes a bio‐electroceutical interface by synergizing engineered exosome‐derived biological signals with electroconductive microneedle‐delivered electrical cues, achieving dual‐pathway reprogramming of the diabetic neurovascular niches and accelerating wound healing. Abstract Diabetic wound healing remains a major clinical challenge due

Substrate Promiscuity of N-Acetylhexosamine 1-Kinases

Molecules, 2011
N-Acetylhexosamine 1-kinase (NahK) catalyzes the direct addition of a phosphate from adenosine 5'-triphosphate (ATP) to the anomeric position of N-acetylhexosamine and shows similar activity towards N-acetylglucosamine (GlcNAc) and N-acetylgalactosamine (
