Regulating Tumor Metabolic Reprogramming with Biomimetic Co‐Delivery of Simvastatin and Kynureninase for Immunotherapy

Advanced Science, EarlyView.
After the intravenous injection of biomimetic and pH/ROS‐responsive PTSK@CRM, the nanoparticles can be accumulated in tumors and release Sim and KYNase to inhibit the tumor growth, regulate the metabolism of cholesterol and Kyn, and reverse the immunosuppressive tumor microenvironment.

Extracellular Vesicle‐Delivered tRF‐His‐GTG‐1 Reprograms Neutrophil Lipophagy and Triggers Inflammation in COVID‐19

Advanced Science, EarlyView.
This study identifies platelet‐derived extracellular vesicles as key immunometabolic regulators in COVID‐19. The delivery of tRF‐His‐GTG‐1 to neutrophils activates TLR8mTOR signaling, disrupts lipophagy, and amplifies NET‐mediated inflammation. Importantly, targeting this axis restores neutrophil homeostasis, offering a potential therapeutic strategy ...

Inactivation of AXL in Cardiac Fibroblasts Alleviates Right Ventricular Remodeling in Pulmonary Hypertension

Advanced Science, EarlyView.
Pulmonary hypertension (PH) is a progressive condition with high morbidity and mortality, largely owing to right ventricular (RV) failure resulting from maladaptive remodeling. Our study provides strong evidence in support of a critical, detrimental role for AXL as a previously unrecognized determinant driving RV fibrotic pathology in PH.

Engineered Mesenchymal Stem Cell–NK Cell Complexes for Spatially Targeted and Functionally Revitalized Cancer Immunotherapy

Advanced Science, EarlyView.
IL‐15‐engineered stem cell–NK cell complexes, assembled via bioorthogonal chemistry, enable effective lung cancer immunotherapy. Abstract Natural killer (NK) cells represent a powerful immunotherapeutic strategy due to their intrinsic cytotoxicity and ability to target tumor cells independently of antigen presentation.

Pulmonary venous abnormalities encountered on pre-radiofrequency ablation mapping multidetector computed tomography

South African Journal of Radiology, 2017
Multidetector computed tomography (MDCT) elegantly renders pulmonary venous anatomy. With increasing numbers of radiofrequency ablation procedures being performed, there is now a greater emphasis on pre-procedure imaging to delineate this anatomy ...

Burn‐Safe Biodegradable Magnetocaloric Composites for Temperature‐Controlled Biomedical Applications

Advanced Science, EarlyView.
This work investigates a magnetocaloric (Mn,Fe)2(P,Si) compound tailored for precise, self‐regulating heating in biomedical use. With a Curie temperature tuned at 43 °C, it enables therapeutic activation without overheating. Encapsulation in a composite ensures controlled temperature rise under an alternating magnetic field (AMF), with high ...
