IRF8 Drives Conventional Type 1 Dendritic Cell Differentiation and CD8+ T Cell Activation to Aggravate Abdominal Aortic Aneurysm Development

open access: yesAdvanced Science, EarlyView.
This study highlights the critical role of IRF8 in the development of AAA. IRF8 activation promotes the differentiation of cDC1s, which in turn recruit and activate CD8+ T cells, contributing to aortic wall degradation. The study identifies the IRF8‐cDC1‐CD8+ T cell axis as a key pathway in AAA progression, offering new potential therapeutic targets to

Exercise without Weight Loss Prevents Seasonal Decline in Vitamin D Metabolites: The VitaDEx Randomized Controlled Trial

open access: yesAdvanced Science, EarlyView.
In people with overweight or obesity, regular exercise even without weight loss or vitamin D supplementation completely prevents the usual winter decline in the vitamin D metabolite that maintains health at a cellular level, 1,25(OH)2D3, and ameliorates the decline in the vitamin D status marker 25(OH)D.

COPS5 Triggers Ferroptosis Defense by Stabilizing MK2 in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
COPS5, which is overexpressed in HCC in an amplification‐ and ATF4‐dependent manner, stabilizes MK2 through deubiquitination and, in turn, induces HSPB1 activation, protecting HCC cells from ferroptosis and thus promoting sorafenib resistance and tumor progression. Abstract Sorafenib, which is proven to serve as a potent ferroptosis inducer, is used as

CNPY2 Aggravates Renal Tubular Cell Ferroptosis in Diabetic Nephropathy by Regulating PERK/ATF4/CHAC1 Pathway and MAM Integrity

open access: yesAdvanced Science, EarlyView.
Canopy FGF signaling regulator 2 (CNPY2) which is contributed to ERS is upregulated in the renal tubules of patients with diabetic nephropathy (DN). Mechanistically, CNPY2 may regulate ferroptosis and MAM integrity in renal tubular epithelial cells through PERK/ATF4/CHAC1 pathway, thereby promoting the progression of DN.

Gelsolin's Protective Role in MASH through F‐Actin Regulation and P53 Degradation

open access: yesAdvanced Science, EarlyView.
Gelsolin (GSN) maintains liver metabolic homeostasis by promoting MDM2‐mediated P53 degradation and inhibiting F‐actin/Yes‐associated protein (YAP) overactivation. Loss of GSN impairs P53 degradation, increases lipid deposition, and enhances YAP‐driven fibrosis and inflammation in metabolic‐associated steatohepatitis.

Targeted STING Activation Using Modified Ultrasound‐Responsive Microbubbles Enhances Immune Checkpoint Blockade Against Melanoma

open access: yesAdvanced Science, EarlyView.
This study explores the use of ultrasound contrast agents loaded with Stimulator of Interferon Genes (STING) agonists as an approach to activate the body's immune system against cancer. Termed Microbubble‐assisted UltraSound‐guided Immunotherapy of Cancer (MUSIC), this strategy effectively inhibits tumor growth and improves survival in mouse models of ...

Pyruvate Carboxylase in Macrophages Aggravates Atherosclerosis by Regulating Metabolism Reprogramming to Promote Inflammatory Responses Through the Hypoxia‐Inducible Factor‐1 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
This study investigates the role of macrophage pyruvate carboxylase (PC) in atherosclerosis (AS) demonstrating that PC upregulation in macrophages promotes metabolism reprogramming to enhance inflammatory responses via the HIF‐1 signaling pathway.

Engineered Hydrogels for Organoid Models of Human Nonalcoholic Fatty Liver Disease

open access: yesAdvanced Science, EarlyView.
Nonalcoholic fatty liver disease (NAFLD) is characterized by lipid accumulation and extracellular matrix stiffening. An in vitro NAFLD model is developed using engineered hydrogels (G′ ≈ 1–6 kPa) and iPSC‐derived hepatic organoids. It is demonstrated that higher stiffness can increase lipid droplet accumulation, fibrosis, and metabolic dysregulation ...

METTL14‐Induced M6A Methylation Increases G6pc Biosynthesis, Hepatic Glucose Production and Metabolic Disorders in Obesity

open access: yesAdvanced Science, EarlyView.
It is shown that obesity is associated with increases in hepatic METTL14 and m6A methylation of G6pc transcript. YTHDF1 and YTHDF3 bind to m6A‐marked G6pc mRNA to increase its synthesis. Hepatocyte‐specific deletion of Mettl14 decreases G6pc m6A methylation, G6pc biosynthesis, and G6pc‐mediated gluconeogenesis, alleviating glucose metabolic defects in ...

Decursin‐Loaded Nanovesicles Target Macrophages Driven by the Pathological Process of Atherosclerosis

open access: yesAdvanced Science, EarlyView.
This study presents decursin, a traditional Chinese medicine monomer, that inhibits lipid accumulation and inflammation in atherosclerosis through PKCδ interaction. A novel targeted delivery system (ALD@EM) is developed to overcome decursin's short half‐life, combining antibody‐mediated targeting, LDL‐facilitated chemotaxis, and enhanced macrophage ...
