Modulation of neurotransmitter release by P2X and P2Y receptors in the rat spinal cord.

abstract：:Depotentiation, the reversal of long-term potentiation (LTP), can be induced by activation of metabotropic glutamate receptors (mGluRs) or NMDA receptors (NMDARs). Although NMDAR-dependent depotentiation is due to a protein phosphatase-dependent erasure of LTP, the notion that mGluR-dependent depotentiation also invol...
