Senescent Cell Derived Artificial Vesicle‐Based Senolytic Sonovaccine Platform with Augmented Lymph Node Delivery and Antigen Cross‐Presentation Efficacy

open access: yesAdvanced Science, EarlyView.
A senolytic sonovaccine platform (SenoVac) is developed, in which senescent cell‐derived vesicles serve as broad senescent cell antigen reservior. The “2‐step” click chemistry strategy for effective lymph node delivery, and ultrasound‐triggered endosomal escape to boost cross‐presentation, ensures efficient senescent cell clearance and disease ...

SIRT6‐Mediated Deacetylation of ATF3 Promotes Silica‐Induced Lung Fibrosis by Enhancing its Nuclear Import via Binding to Importin α

open access: yesAdvanced Science, EarlyView.
SIRT6‐mediated ATF3 acetylation drives MGARP transcription and mitochondrial dysfunction in macrophages, promoting macrophage senescence and pulmonary fibrosis. Mechanistically, HSP70/Importin α competitively binds to ATF3, modulating its nuclear translocation.

Mechanically Regulated Nanozymes for Remote Metabolic Reprogramming and Precise Cancer Therapy

open access: yesAngewandte Chemie, EarlyView.
Inspired by mechanoenzymes, a ferrocene‐based mechanically regulated nanozyme converts acoustic shear force into enhanced peroxidase‐like activity by decreasing electron density and alleviating steric hindrance at the Fe active sites, thereby rewiring redox homeostasis. Leveraging this remote regulatory mechanism, a multienzyme‐regulated nanoreactor is

Renal IGFBP6 Interacts With THBS1 to Drive Renal Cellular Senescence and Fibrosis

open access: yesAdvanced Science, EarlyView.
ABSTRACT Epithelial dedifferentiation and myofibroblast activation are critical drivers of chronic kidney disease (CKD) progression. Elevated levels of IGFBP6 have been linked to decreased renal function in CKD patients, but its precise role and underlying mechanisms remain unclear.

Pathological Mechanism‐Inspired Biomimetic Nano‐Senotherapy for Reversing Experimental Atherosclerosis in ApoE−/− Mice

open access: yesAdvanced Science, EarlyView.
The biomimetic self‐assembly nanomedicine reversing atherosclerosis via senotherapy strategy. ABSTRACT The greatest challenge in atherosclerosis (AS) management lies in achieving lesion reversal, not merely slowing progression. Senescent cell accumulation—driven by continuous generation and apoptotic resistance—perpetuates plaque pathology and ...

Galactosialidosis in two siblings

open access: yesThe Turkish Journal of Pediatrics, 1996
Galactosialidosis is a rare lysosomal storage disease associated with deficiencies of alpha-galactosidase and beta-neurominidase. In this report, two siblings with galactosialidosis, resembling Niemann-Pick disease with the presence of foamy cells
