Effects of miR-219/miR-338 on microglia and astrocyte behaviors and astrocyte-oligodendrocyte precursor cell interactions
Lan Huong Nguyen, William Ong, Kai Wang, Mingfeng Wang, Dean Nizetic, Sing Yian ChewNeural Regeneration Research 2020 15(4):739-747MiR-219 and miR-338 (miR-219/miR-338) are oligodendrocyte-specific microRNAs. The overexpression of these miRs in oligodendrocyte precursor cells promotes their differentiation and maturation into oligodendrocytes, which may enhance axonal remyelination after nerve injuries in the central nervous system (CNS). As such, the delivery of miR-219/miR-338 to the CNS to promote...
