N-Docosahexaenoylethanolamine is a potent neurogenic factor for neural stem cell differentiation.

ABSTRACT: Docosahexaenoic acid (DHA) has been shown to promote neuronal differentiation of neural stem cells (NSCs) in vivo and in vitro. Previously, we found that N-docosahexaenoylethanolamine (synaptamide), an endogenous DHA metabolite with an endocannabinoid-like structure, promotes neurite growth, synaptogenesis, and synaptic function. In this study, we demonstrate that synaptamide potently induces neuronal differentiation of NSCs. Differentiating NSCs were capable of synthesizing synaptamide from DHA. Treatment of NSCs with synaptamide at low nanomolar concentrations significantly increased the number of MAP2 and Tuj-1-positive neurons with concomitant induction of protein kinase A (PKA)/cAMP response element binding protein (CREB) phosphorylation. Conversely, PKA inhibitors or PKA knockdown ab
