 However, given "in vivo" studies performed by this group, the Y1 receptor displayed specifically mediated neuroproliferative effects through the induction of NPY with increased expression in the subventricular zone.Identification of the Y1 receptor also sheds light on the fact that the phenotype of expressed cells from such mitotic events are actually cells that are DCX+ (neuroblasts that migrate directly to the striatum) type.Along with the effects of NPY injection on striatal dopamine, GABA and glutamate parameters to regulate neurogenesis in the subventricular zone (previous study), this finding is still under consideration as it could be a secondary modulator of the aforementioned neurotransmitters.
