Neutrophil–Endothelium Interaction Mediated by S100A9 Promotes Pulmonary Vascular Remodeling During Pulmonary Hypertension

open access: yesAdvanced Science, EarlyView.
This study investigates the critical mechanisms underlying pulmonary hypertension progression, with a focus on the novel role of neutrophil‐derived S100A9 in endothelial dysfunction‐mediated pulmonary vascular remodeling. By integrating human lung samples, multi‐omics analyses, animal models, and mechanistic in vitro studies, it is revealed that how ...

Gut Parabacteroides distasonis‐derived Indole‐3‐Acetic Acid Promotes Phospholipid Remodeling and Enhances Ferroptosis Sensitivity via the AhR‐FASN Axis in Bladder Cancer

open access: yesAdvanced Science, EarlyView.
Indole‐3‐acetic acid (3‐IAA) derived from gut P. distasonis binds to AhR in bladder cancer cells and downregulates FASN transcription, thereby increasing sensitivity to ferroptosis and suppressing the development of bladder tumors. Specifically, 3‐IAA treatment leads to an increase in the proportion of PC/PE‐PUFAs and a decrease in the proportions of ...

KRAS mRNA Spleen‐Targeting Lipid Nanoparticles Synergize with Irinotecan Silicasomes to Robustly Augment the Cancer Immunity Cycle in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
To overcome pancreatic cancer's immunosuppressive barriers, this study explores a dual approach: triggering immunogenic tumor cell death at the primary tumor site with irinotecan‐loaded silicasomes and enhancing immune activation in the spleen using LNPs encapsulating tumor antigen mRNA and a TLR7/8 agonist.

Megasphaera Elesdenii Dysregulates Colon Epithelial Homeostasis, Aggravates Colitis‐Associated Tumorigenesis

open access: yesAdvanced Science, EarlyView.
A fecal microbial meta‐analysis reveals that Megasphaera is highly abundant in the Asian population with IBD and CRC. M. elsdenii reshapes colonic immunity by triggering DC cell‐mediated Th1 and Th17 inflammation. M. elsdenii and M. elsdenii‐enriched microbiota exacerbate colonic inflammation and tumorigenesis in AOM/DSS mice.

Extracts of Chuanxiong and Baizhi Attenuate Neuroinflammation in Chronic Migraine Rats by Inhibiting TLR4/MyD88/Nuclear Factor Kappa B Signal Pathway

open access: yesJournal of Physiological Investigation
This study investigates the mechanism by which a compound mixture of Chuanxiong and Baizhi (CMCB) modulates the TLR4/MyD88/nuclear factor kappa B (NF-κB) pathway to alleviate neuroinflammation in nitroglycerin (NTG)-induced chronic migraine (CM) rat ...
