Targeting a Myeloid–Regulatory B Cell Network Reverses Immune Paralysis in Periprosthetic Joint Infections

Advanced Science, EarlyView.
Periprosthetic joint infection establishes a sophisticated immunosuppressive network between CXCR4+ PMN‐MDSCs and Bregs, inducing profound CD8+ T cell paralysis. Alendronate effectively disrupts this CXCR4+ PMN‐MDSC–Breg axis by targeting STAT3, thereby restoring local immune surveillance.

Identification and characterization of arginase II as a chondrocyte phenotype‐specific gene [PDF]

IUBMB Life, 2006
AbstractWe have previously shown that activation of extracellular signal‐regulated protein kinase‐1 and ‐2 (ERK1/2) causes chondrocyte dedifferentiation, which contributes to the destruction of arthritic cartilage. In the present study, we identified genes involved in the ERK1/2 regulation of chondrocyte dedifferentiation. Several genes were identified

A Blood‐Derived Double‐Network Hydrogel with Robust Wet Adhesion for Keratinized Mucosa Regeneration via Neutrophil Phenotype Reprogramming and Mechanophysical Niche Modulation

Advanced Science, EarlyView.
The iPRF‐MA/Alg‐NHS/Lut@EGCG (PGAE) double‐network hydrogel achieves durable wet adhesion in the oral environment. It simultaneously reprograms neutrophils from NETosis to phagocytosis for biofilm clearance, and activates the FAK‐RhoA‐YAP mechanotransduction pathway in gingival fibroblasts to drive extracellular matrix remodeling, thereby promoting ...

Vascularized Liver‐on‐a‐Microsphere Reveals Alanine‐Glucose Metabolism‐Driven Regulation of Liver Function and Injury

Advanced Science, EarlyView.
A vascularized liver‐on‐a‐microsphere system is developed to recreate lobule‐like cellular organization and endothelial barrier function within compartmentalized hydrogel particles. The platform enhances hepatic performance and reveals alanine‐glucose cycle activation linked to improved detoxification capacity, offering a high‐throughput microscale ...

CD177 Deficiency Defines a Stable Subtype of Human Neutrophil Granulocytes with Tumor Promoting Activity

Advanced Science, EarlyView.
Human neutrophils exist as two epigenetically imprinted subtypes defined by stable CD177 expression or absence — a ratio that persists across time, circadian rhythms, and inflammation. CD177− neutrophils display a distinct molecular landscape enriched in arginase 1 and lipid metabolism markers, accumulate in head‐and‐neck tumors, and associate with ...

RETRACTED: Arginase II - a new target in the development of endothelium protectors

Регуляторные исследования и экспертиза лекарственных средств, 2018
RETRACTED ARTICLEThe article describes arginase’s role in pathogenesis of endothelial dysfunction and a number of cardio-vascular diseases. Arginase catalyzes the hydrolysis of L-arginine, the substrate for nitric oxide synthesis, to L-ornithine and urea.

Effects of Arginase I and II on the local production of NO

The FASEB Journal, 2009
Endothelial Nitric Oxide Synthase (eNOS) produces nitric oxide (NO) within the endothelial cell layer of blood vessels. NO is a potent vasodilator and perturbations of NO signaling have been associated with cardiovascular diseases such as diabetes, atherosclerosis and hypertension.

Light‐Activated Ruthenium Nanoclusters Reprogram the Metabolic‐Quorum Sensing Axis for Precision Periodontitis Therapy

Advanced Science, EarlyView.
Under 660 nm visible light, Ru NCs efficiently photocatalyze nitrate‐to‐ammonium conversion and modulate oral nitrogen metabolism. They precisely perturb Veillonella parvula, block its key support to Porphyromonas gingivalis, and exert an “inhibiting without killing” antivirulence effect.
