Secondary metabolites of Alternaria alternate appraisal of their SARS-CoV-2 inhibitory and anti-inflammatory potentials.
PLoS One
January 2025
Department of Pharmacognosy, Faculty of Pharmacy, Helwan University, Cairo, Egypt.
This study identifies the secondary metabolites from Alternaria alternate and evaluates their ACE-2: Spike RBD (SARS-CoV-2) inhibitory activity confirmed via immunoblotting in human lung microvascular endothelial cells. In addition, their in vitro anti-inflammatory potential was assessed using a cell-based assay in LPS-treated RAW 264.7 macrophage cells.

Many cell types are involved in the regulation of cutaneous wound healing in diabetes. Clarifying the mechanism of cell-cell interactions is important for identifying therapeutic targets for diabetic cutaneous ulcers. The function of vascular endothelial cells in the cutaneous microenvironment is critical, and a decrease in their biological function leads directly to refractory wound healing.

Purpose: A human model able to simulate the manifestation of corneal endothelium decompensation could be advantageous for wound healing and future cell therapy assessment. The study aimed to establish an ex vivo human cornea endothelium wound model where endothelium function can be evaluated by measuring corneal thickness changes.
Methods: The human cornea was maintained in an artificial anterior chamber, with a continuous culture medium infusion system designed to sustain corneal endothelium and epithelium simultaneously.
3-HKA Promotes Vascular Remodeling After Stroke by Modulating the Activation of A1/A2 Reactive Astrocytes.

Ischemic stroke is the most common cerebrovascular disease and the leading cause of permanent disability worldwide. Recent studies have shown that stroke development and prognosis are closely related to abnormal tryptophan metabolism. Here, significant downregulation of 3-hydroxy-kynurenamine (3-HKA) in stroke patients and animal models is identified.

Department of Ophthalmology, Affiliated Hospital of North Sichuan Medical College, Nanchong, Sichuan, China.
Purpose: Ocular neovascularization is a major cause of blindness. Although fibroblast growth factor-2 (FGF2) has been implicated in the pathophysiology of angiogenesis, the underlying mechanisms remain incompletely understood. The purpose of this study was to investigate the role of FGF2 in retinal neovascularization and elucidate its underlying mechanisms.
