We had found previously that neurotrophin-3 (NT-3) is a potent stimulator of cAMP-response element binding protein (CREB) phosphorylation in cultured oligodendrocyte progenitors. Here, we show that CREB phosphorylation in these cells is also highly stimulated by sphingosine-1-phosphate (S1P), a sphingolipid metabolite that is known to be a potent mediator(More)
Neurotrophin-3 (NT-3) regulates oligodendrocyte (OLG) differentiation by mechanisms that remain poorly understood. Exposure of OLGs to NT-3 induces a significant increase in the levels of myelin basic protein (MBP). However, we found that this stimulation occurs in the absence of measurable effects on MBP gene promoter activation or mRNA expression,(More)
