Does the Gut Microbiome Contribute to Age-Related Anabolic Resistance

The gut microbiome is a highly varied collection of microbial populations that acts in symbiosis with the body to process food and provide needed metabolites. With age, there is a detrimental shift in these populations. Those generating useful metabolites, such as butyrate, diminish in number. Those capable of infiltrating tissue, […]

Cell-based method for the regeneration of myelin

Myelin is tremendously important for the correct and rapid transmission of electrical signals in the brain. This lipid-rich membrane, which wraps axons, is damaged in certain degenerative nerve disorders. Most of these are rare hereditary diseases with serious clinical courses. Generation of induced oligodendrocyte progenitor cells (iOPCs) from somatic fibroblasts […]
