Article Abstract
Preserving denatured dermis has been shown to promote wound healing and improve skin appearance and function. Angiogenesis is crucial for the healing of burn wounds. However, the metabolic mechanisms underlying angiogenesis during burn recovery remain unclear. In this study, ultra-high performance liquid chromatography-mass spectrometry analysis revealed 6 distinct metabolites in a heat-denatured cell model. A bioinformatics approach was used to predict the differentially expressed metabolites and 4 metabolic pathways closely related to trauma repair were identified. These pathways might play a significant role in the regression of thermally injured endothelial cells. We also found that increasing D-mannose level promoted the angiogenic activity of human umbilical vein endothelial cells in the heat-denatured cell model, enhancing cell proliferation, migration, and tube formation. In summary, these findings revealed changes in metabolites and metabolic pathways in thermally injured endothelial cells and demonstrated that D-mannose could promote angiogenesis during the recovery of thermally injured endothelial cells.

Distinct interleukin-6 production in IPL and TAFRO subtypes of idiopathic multicentric Castleman disease.

Idiopathic multicentric Castleman disease (iMCD) is a rare lymphoproliferative disorder characterized by systemic inflammation and lymphadenopathy. Two major clinical subtypes, idiopathic plasmacytic lymphadenopathy (iMCD-IPL) and iMCD with thrombocytopenia, anasarca, fever, renal dysfunction/reticulin fibrosis, and organomegaly (iMCD-TAFRO), exhibit distinct pathophysiologic mechanisms. While interleukin-6 (IL-6) is known to be elevated in iMCD, the differences in IL-6 production sources between subtypes remain unclear.

Background: Atherosclerosis is a chronic inflammatory disease characterized by the accumulation of lipid-laden foam cells and plaques within the arterial wall. Dysfunctional vascular smooth muscle cells (VSMCs), fibroblasts, endothelial cells, and macrophages contribute to disease progression. Here, we report that macrophage-specific expression of epsins, highly conserved endocytic adaptor proteins involved in clathrin-mediated endocytosis, accelerates atherosclerosis in Western diet-fed mice.

Background: Diabetic retinopathy (DR) is a major complication of diabetes mellitus, characterised by retinal vasculopathy and oxidative stress. Semaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1RA), has demonstrated cardiovascular benefits but has also been associated with mixed effects on DR progression. This study investigates the potential of semaglutide to attenuate DR progression by ameliorating retinal vasculopathy and oxidative stress in both in vivo and in vitro models.

Oncometabolites are aberrant metabolic byproducts that arise from mutations in enzymes of the tricarboxylic acid (TCA) cycle or related metabolic pathways and play central roles in tumor progression and immune evasion. Among these, 2-hydroxyglutarate (2-HG), succinate, and fumarate are the most well-characterized, acting as competitive inhibitors of α-ketoglutarate-dependent dioxygenases to alter DNA and histone methylation, cellular differentiation, and hypoxia signaling. More recently, itaconate, an immunometabolite predominantly produced by activated macrophages, has been recognized for its dual roles in modulating inflammation and tumor immunity.

Endothelial Colony-Forming Cells (ECFCs) are recognized as key vasculogenic progenitors in humans and serve as valuable liquid biopsies for diagnosing and studying vascular disorders. In a groundbreaking study, Anceschi et al. present a novel, integrative strategy that combines ECFCs loaded with gold nanorods (AuNRs) to enhance tumor radiosensitization through localized hyperthermia.
