Hydrogen Sulfide Prevents ATP-induced Neurotoxicity via Inhibiting The NLRP1/caspase-1/ gasdermin D-mediated Pyroptosis Pathway

Shengwu huaxue yu shengwu wuli jinzhan
ObjectiveStroke is a leading cause of death and disability worldwide, with ischemic stroke accounting for 80%-85% of cases. Despite the prevalence, effective treatments remain scarce. The compelling evidence suggest that high concentrations of ATP in the

Early Retinal UCHL1 Dysregulation Coupled With Synaptic Loss Reflects Alzheimer's Disease Severity

Advanced Science, EarlyView.
This study identifies synapse‐enriched deubiquitinase UCHL1 as an early Aβ‐responsive regulator of retinal synaptopathy in Alzheimer's disease. Retinal UCHL1 loss accompanies excitatory synapse degeneration, p75NTR activation, and neuroinflammation, and predicts Braak stage and cognitive decline. Aβ42 fibrils trigger synaptic and UCHL1 depletion before

Lactate‐Driven Restriction of Mitochondrial Permeability Transition Promotes Resistance to Chemo‐Immunotherapy by Suppressing Tumor PANoptosis

Advanced Science, EarlyView.
Tumor‐derived lactate establishes a metabolic lock that drives chemo‐immunotherapy resistance by suppressing PANoptosis. Mechanistically, KAT8 lactylates the mitochondrial translocator ANT2, which recruits PGAM5 to dephosphorylate CypD. This cascade restricts mitochondrial permeability transition pore opening, preventing pro‐inflammatory mtDNA leakage.

Environmental toxin chlorpyrifos induces liver injury by activating P53-mediated ferroptosis via GSDMD-mtROS

Ecotoxicology and Environmental Safety, 2023
Aim: We investigate the mechanism whereby chlorpyrifos (CHI), an environmental toxin, causes liver injury by inducing ferroptosis in hepatocytes. Methods: The toxic dose (LD50 = 50 μM) of CHI for inducing AML12 injury in normal mouse hepatocytes was ...

A Plant Photoregulator‐Inspired S‐Type Heterojunction System for Diabetic Keratopathy via Tri‐Modal Light‐Driven Immunometabolic Reprogramming, Tissue Repair, and Antibacterial Activity

Advanced Science, EarlyView.
To address the multifaceted imbalance in diabetic keratopathy, a light‐responsive biomimetic platform (WCNx‐Rh2) is developed and integrates glucose degradation, immune modulation, and antibacterial defense through a designed heterojunction and screened immunomodulator. WCNx‐Rh2 reduces AGEs/ROS and inflammatory signaling, reprogramming dendritic cells

Targeting NSUN2‐Mediated m5C Modification Attenuates Chondrocyte Senescence and NLRP3 Activation in Osteoarthritis

Advanced Science, EarlyView.
NSUN2‐mediated m5C modification cooperates with ALYREF to stabilize and export IP3R3 mRNA, increasing IP3R3 expression and Ca2 + overload in chondrocytes. This signaling promotes mitochondrial dysfunction, NLRP3 inflammasome activation, and senescence, thereby accelerating osteoarthritis progression.

Gasdermin D–mediated pyroptosis suppresses liver regeneration after 70% partial hepatectomy

Hepatology Communications, 2022
Pyroptosis is a kind of programmed cell death primarily mediated by gasdermin D (GSDMD) and shown to regulate multiple diseases. However, its contribution to liver regeneration, a fine‐tuned tissue repair process mediated primarily by hepatocytes after ...

Disulfiram Attenuates Adenine-Induced Renal Fibrosis by Modulating Inflammatory and Immunometabolic Responses. [PDF]

FASEB J
Chronic kidney disease (CKD) is characterized by persistent inflammation that drives progressive renal injury and fibrosis. In this study, we demonstrate that disulfiram markedly attenuates kidney injury and fibrosis in adenine‐induced nephropathy by suppressing innate immune responses and reducing DNA damage and cellular senescence.

Western blot showed the expression level of cleaved GSDMD-NT in PC12 cells (n = 3).

, 2022
The expression level of cleaved GSDMD-NT was significantly increased after treatment with DEX, and siRNA GSDMD can significantly alleviate the effects of DEX. The data are shown as the mean ± SEM, **P #P < 0.05 compared to the DEX + siRNA NC group. GSDMD:

Fatty Acid Binding Protein 5 Mediates Astrocytic Pyroptosis and Neuroinflammation in Epilepsy via cGAS/STING Pathway

Advanced Science, EarlyView.
Astrocytic FABP5 promotes mitochondrial stress, cGAS‐STING pathway activation, pyroptosis, and neuroinflammation in epilepsy, contributing to seizure pathology. Genetic targeting of FABP5 or pharmacological inhibition of STING alleviates epileptic phenotypes, highlighting a potential therapeutic strategy for epilepsy.
