Abstract
Transplantation of genetically modified oligodendrocyte progenitor cells (OPCs) into a mouse model of MS improves remyelination, new research has demonstrated. The researchers used CRISPR in human embryonic stem cell-derived OPCs to delete neuropilin 1, a receptor for SEMA3A that is highly expressed in demyelinated lesions in people with MS and is chemorepulsive to OPCs. Transplantation of the modified OPCs enhanced remyelination in the mice, providing proof of concept for OPC transplantation as a potential therapeutic strategy for MS.
期刊介绍：
Biochemistry provides an international forum for publishing exceptional, rigorous, high-impact research across all of biological chemistry. This broad scope includes studies on the chemical, physical, mechanistic, and/or structural basis of biological or cell function, and encompasses the fields of chemical biology, synthetic biology, disease biology, cell biology, nucleic acid biology, neuroscience, structural biology, and biophysics. In addition to traditional Research Articles, Biochemistry also publishes Communications, Viewpoints, and Perspectives, as well as From the Bench articles that report new methods of particular interest to the biological chemistry community.
