Microglial Fkbp5 Impairs Post‐Stroke Vascular Integrity and Regeneration by Promoting Yap1‐Mediated Glycolysis and Oxidative Phosphorylation

Advanced Science, EarlyView.
A post‐stroke perivascular niche of microglia characterized by low expression of M2 markers and elevated glycolysis, oxidative phosphorylation (OXPHOS), and phagocytic activity is identified, which is termed stroke‐activated vascular‐associated microglia (stroke‐VAM).

Folic Acid‐Modified Ginger‐Derived Exosome‐Like Nanoparticles Co‐Delivering Sunitinib Suppress Renal Cell Carcinoma via PI3K‐Akt Pathway Inhibition, P‐gp Downregulation, and Macrophage Reprogramming

Advanced Science, EarlyView.
FPD‐GELNs co‐deliver Su and bioactive components. This active‐passive dual‐targeting strategy suppresses the progression of RCC through the following mechanisms: 1) inhibition of the PI3K‐Akt signaling pathway; 2) downregulation of ABCB1/P‐gp to enhance the chemosensitivity of RCC to Su; and 3) reprogramming of macrophages toward M1 polarization and ...

Ultrasound‐Boosted Liposomal Prodrug Overcomes Age‐Associated Biodistribution Disparity in Pediatric Solid Tumor Therapy

Advanced Science, EarlyView.
The age‐associated disparity of nanocarrier biodistribution limits the nanotherapeutics of childhood solid tumors. This study developed an ultrasound‐activated liposomal prodrug (CSCPTL) to overcome the age‐associated disparity of off‐target distribution.

Magnetically‐Induced Suppression of Oxidative Stress Prevents Venous Thrombosis

Advanced Science, EarlyView.
Venous thromboembolism (VTE) remains a leading cause of cardiovascular mortality. This study demonstrates that static magnetic fields (SMF) offer a novel non‐pharmacological intervention against VTE by mitigating endothelial oxidative stress. Mechanistically, SMF elevates intracellular Ca2+, boosts ATP production, and suppresses NOX4‐mediated ROS ...

Platelet Activating Factor (PAF): A Mediator of Inflammation

Biofactors, 2022
Platelet‐activating factor (PAF) is a phospholipid‐derived mediator with an established role in multiple inflammatory states. PAF is synthesized and secreted by multiple cell types and is then rapidly hydrolyzed and degraded to an inactive metabolite ...

COVID‐19, microthromboses, inflammation, and platelet activating factor

Biofactors, 2020
Recent articles report elevated markers of coagulation, endothelial injury, and microthromboses in lungs from deceased COVID‐19 patients. However, there has been no discussion of what may induce intravascular coagulation.
