SAA/FPR2 Signaling Between Pericentral Hepatocytes and Macrophages Exacerbates Zonated Liver Transplant Injury

Advanced Science, EarlyView.
After liver transplantation, ischemia‐reperfusion injury is more severe in pericentral regions. Multiomic analyses of human grafts and mouse models identify FOXO1 activation in pericentral hepatocytes as an upstream driver of SAA secretion. SAA recruits and activates FPR2+ macrophages, amplifying local inflammation. Amilo‐5MER inhibits SAA bioactivity,

Gasdermin D‐Mediated Release of IL‐33 Results in Fetal Brain Developmental Abnormalities During Maternal Colitis

Advanced Science, EarlyView.
Under colitis, Gsdmd mediates the release of IL‐33 from the epithelium of pregnant mice. IL‐33 can cross the placenta and enhance the proliferative capacity of neural stem cells, ultimately resulting in behavioral deficits in the offspring. Excessive pyroptosis in the colonic epithelium also triggers the translocation of LPS, which in turn increases ...

Mechanically Robust Biodegradable Stents With Theragenerative Vascular Responses via Combined 3D Printing and Janus Nanoengineering

Advanced Science, EarlyView.
This work introduces a theragenerative 3D‐printed biodegradable stent with Janus nanoarchitecture for spatially controlled vascular healing. A luminal tantalum ion–implanted surface accelerates endothelialization and hemocompatibility, while an abluminal sirolimus/poly‐L‐lactic acid–tantalum layer provides sustained drug release and suppresses smooth ...

Ultrasound Activated Piezoelectric Dural Patches to Drive Endogenous Neural Stem Cell–Mediated Repair Traumatic Brain Injury

Advanced Science, EarlyView.
This study presents a wireless, non‐invasive strategy for neural repair by developing a biodegradable piezoelectric dural patch that, under transcranial ultrasound, generates localized electrical fields to drive endogenous neural stem cells toward neuronal differentiation and functional integration.

A Biomimetic Nanoparticle System Intercepts and Degrades Thrombospondin‐1 to Restore Vascular Homeostasis After Ischemic Injury

Advanced Science, EarlyView.
TAX2‐NPs capture extracellular TSP‐1 in the injured liver and promote its macrophage‐mediated autophagic degradation. This process blocks TSP‐1/CD47 signaling, restores VEGFR2‐AKT activity, preserves endothelial function, and mitigates hepatic ischemia‐reperfusion injury.

T Cell‐Independent Role of PD‐L1 in Kidney Repair: Mitigation of Tubular DNA Damage via PD‐L1/BRCA1 Interaction Following AKI

Advanced Science, EarlyView.
PD‐L1 is primarily expressed in renal tubules and upregulated in both murine models of AKI and renal biopsy samples from patients with AKI. PD‐L1 can promote adaptive TECs repair through interacting with BRCA1, independent of its canonical immunomodulatory function of T cells, and PD‐L1 supplementation may represent a promising therapeutic strategy for

Biomimetic Bone Marrow Monocyte Membrane‐Fused Extracellular Vesicles for Targeted Therapy of Myocardial Infarction

Advanced Science, EarlyView.
This study develops a biomimetic delivery system (M‐hEV) by fusing monocyte membranes with extracellular vesicles for targeted therapy of damaged cardiac tissue. The system homes to injured myocardium through specific molecular pathways. In a myocardial infarction model, M‐hEV effectively accumulates in the heart, reduces infarct size, alleviates ...

Isovolumic relaxation strain imaging is an accurate and sensitive approach for detection of active diastolic dysfunction: A preclinical study

Animal Models and Experimental Medicine, EarlyView.
A modified approach was developed to accurately identify the isovolumetric relaxation time (IVRT) using an apical three‐chamber view. Compared with conventional echocardiography, isovolumic relaxation strain imaging (IVSI) helps to detect the earlier alternations of diastolic function in transverse aortic constriction (TAC) mice.
