Glutathione

Glutathione is a natural antioxidant

Glutathione (GSH) is a naturally occurring antioxidant produced by the liver and central nervous system that is said to help metabolize toxins, break down free radicals, support immune function, and more. Researchers have explored its potential use for diseases such as cystic fibrosis, chemotherapy-related toxicity, and Parkinson’s disease. There is currently insufficient scientific evidence to…

Maintaining redox homeostasis to regulate efficient glutathione metabolism in Corynebacterium glutamicum

Research points This article investigates the metabolic mechanism of glutathione (GSH) as an antioxidant in Corynebacterium glutamicum, and constructs an efficient glutathione producing strain through metabolic engineering and fermentation optimization strategies. Research has found that by modifying glutathione synthase (GshF), knocking out genes related to hydrogen sulfide production and glutathione degradation, and combining with overexpression…

Extracellular vesicle-mediated VEGF-A mRNA delivery rescues ischaemic injury with low immunogenicity

A novel gene therapy for ischemic heart disease based on engineered external vesicles with high efficiency and low immunogenicity

Ischemic injury is the number one cause of death and disease in the world, including the United States and China, and vascular endothelial growth factor (VEGF) gene therapy holds promise for patients with ischemic injury. However, the high immunogenicity of traditional viral vectors (such as adeno-associated virus AAV) and the low expression efficiency of lipid…
