Oral Recombinant Human Collagen III Protects Gastric Mucosa via G‐Quadruplex‐Mediated Activation of the Pla2g4a‐Prostaglandin Axis

open access: yesAdvanced Science, EarlyView.
Orally administered recombinant human type III collagen protects the gastric mucosa from ethanol‐induced injury by coordinating redox homeostasis, epithelial barrier repair, and arachidonic acid–prostaglandin metabolism. Gastric digestion releases the pentapeptide GPAEF, which interacts with the Pla2g4a promoter G‐quadruplex in a structure‐dependent ...

AI‐Designed TREM1‐Targeted LYTAC Nanoparticles Reprogram the Neuroimmune Microenvironment in Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
AI‐enabled de novo design of a TREM1 binder, integrated into a BBB‐crossing and macrophage‐targeted nanoplatform, enables TREM1 degradation and attenuates neuroinflammation, thereby promoting neuroprotection and tissue repair after traumatic brain injury. ABSTRACT Secondary neuroinflammation drives progressive damage after traumatic brain injury (TBI),

Neonatal Sevoflurane Exposure Induces Long‐Term Cognitive Impairment via Epigenetically Mediated MMP9 Activation and Perineuronal Net Disruption in the Hippocampal CA2

open access: yesAdvanced Science, EarlyView.
Hippocampal CA2 perineuronal nets ensheathing excitatory pyramidal neurons are selectively vulnerable to repeated neonatal sevoflurane exposure. Epigenetic upregulation of MMP9 via reduced H3K27me3 disrupts PNN integrity, impairs BDNF–TrkB signaling, and causes synaptic protein loss and dendritic spine deficits, leading to persistent social and spatial

T‐Cell Remodeling in Renal Fibrosis: From Acute Injury to Chronic Kidney Disease

open access: yesAdvanced Science, EarlyView.
This Review presents renal fibrosis as a sequence of overlapping T‐cell programs, from chemokine‐guided recruitment and metabolic activation to maladaptive polarization, tertiary lymphoid structure formation, tissue residency, exhaustion, and senescence.

In Situ Photo‑Crosslinked Functional Bilayer Hydrogel Modulates Local Microenvironment and Remyelination After Optic Nerve Injury

open access: yesAdvanced Science, EarlyView.
A blue‐light‐crosslinked bilayer hydrogel was developed for local optic nerve repair. The adhesive GM‐Odex outer layer seals and anchors the lesion, while the non‐adhesive GM‐imid inner layer releases MPDA‐Cle without obstructing CSF flow. This system modulates oxidative and inflammatory microenvironments, supports oligodendrocyte differentiation and ...
