We investigated the effect of nobiletin on the oligodendroglial cell lineage in a cuprizone-induced demyelination animal model. Nobiletin, a polymethoxyflavone, was administered to the model animal for 3 consecutive weeks (50 mg/kg, intraperitoneally, 2 times/week). Immunohistochemical analysis of the corpus callosum and/or Western blotting analysis of brain extracts revealed that cuprizone administration reduced immunoreactivity for myelin-basic protein (MBP), a marker for mature oligodendrocytes, and increased immunoreactivity for platelet derived-growth factor receptor (PDGFR)-α, a marker for oligodendrocyte precursor cells (OPCs). Nobiletin treatment did not affect these changes in the cuprizone-fed mice. Nobiletin treatment, however, increased the immunoreactivity against proteolipid protein (PLP)/DM-20, a marker for mature oligodendrocytes, OPCs, and oligodendrocyte lineag.. Read More»
