    ..These results suggest that the elevated expression of NPY in the ventromedial nucleus may contribute to the state of leptin resistance that occurs during pregnancy. ..

    ..Thus, Y1 signaling in hematopoietic-derived cells such as macrophages is critical for the control of inflammation and insulin resistance in obesity. ..

    ..These data indicate that ATP initiates neuroproliferation via NPY upregulation, NPY release, and Y1 receptor activation, and suggests that the olfactory epithelium is good model to study neuroregenerative mechanisms in the CNS...
