Article Abstract
Extracellular matrix proteins harbor signaling domains that once released from the parent molecule can trigger cellular responses. One of these molecules is endotrophin, a type VI collagen derived fragment, whose circulatory levels have been associated to an increased risk of adverse outcome in heart failure with preserved ejection fraction (HFpEF). Here we show that the stimulation of human cardiac fibroblasts by endotrophin upregulates the synthesis of type I collagen, the main interstitial collagen that accumulates in the myocardium during fibrogenesis. These data provide a possible mechanistic explanation for the relation between circulating endotrophin levels and risk of outcome in HFpEF.

Bacterial infection in the injured skin may threaten the wound repair and skin regeneration owing to aggravated inflammation. The multifunctional dressings with persistent antibacterial activity and improved anti-inflammatory capability are urgently required. Herein, a type of heterogeneous zinc/catechol-derived resin microspheres (Zn/CFRs) composed of zinc ions (Zn) and zinc oxide (ZnO) nanoparticles was developed to impart the methacrylamide chitosan (CSMA)-oxidized hyaluronic acid (OHA) hydrogel with a persistent Zn release behavior.

Orthodontic-induced gingival enlargement (OIGE) affects approximately 15-30% of patients undergoing orthodontic treatment and remains largely unpredictable, often relying on subjective clinical assessments made after irreversible tissue changes have occurred. S100A4 is a well-characterized marker of activated fibroblasts involved in pathological tissue remodeling. This was a cross-sectional precision biomarker study that analyzed gingival tissue samples from three groups: healthy controls (n = 60), orthodontic patients without gingival enlargement (n = 31), and patients with clinically diagnosed OIGE (n = 61).

Neutrophils play a complex role in the pathogenesis of chronic liver disease and have been linked to both liver damage and injury resolution. Recent reports propose that neutrophils drive liver injury and fibrosis through the formation of neutrophil extracellular traps (NETs). This study tests the hypothesis that the enzyme peptidyl arginine deiminase-4 (PAD4) drives NET formation and liver fibrosis in experimental chronic liver injury.

To evaluated the efficacy of photodynamic therapy (PDT) in improving laryngeal mucosal wound scar healing in vivo and investigated its underlying mechanisms. Laryngeal mucosal wounds were induced in Sprague-Dawley rats. Two weeks post-injury, PDT was administered via intraperitoneal injection of 100 mg/kg 5-aminolevulinic acid (5-ALA) and 635-nm red laser irradiation at varying energy doses (15, 30, and 45 J/cm²).
