Spatially concentrated adenine base editors efficiently correct PLP1 mutations in oligodendrocytes.

Abstract excerpt

Oligodendrocytes (OLs), the myelinating cells of the central nervous system, are particularly prone to pathogenic G-to-A mutations, such as PLP1A243V, which causes Pelizaeus-Merzbacher disease (PMD), a lethal hypomyelinating disorder lacking effective therapy. Although adenine base editors (ABEs) can in principle correct such mutations, their application in OLs is limited by inefficient on-target editing. Here,...
