General description
Disks large homolog 4 (UniProt P78352; also known as Postsynaptic density protein 95, PSD-95, SAP-90, SAP90, Synapse-associated protein 90) is encoded by the DLG4 (also known as PSD95) gene (Gene ID 1742) in human. PSD-95 belong to the family of membrane-associated guanylate kinases (MAGUKs), which also include PSD-93, SAP97 and SAP102. PSD95 is predominantly expressed in the hippocampus CA1 region and prefrontal cortex of the brain, where it localizes in a somatodendritic pattern in the post-synaptic membrane and in presynaptic axon terminals of inhibitory neurons. PDS-95 is the major scaffolding protein in the excitatory postsynaptic density (PSD) and a potent regulator of synaptic strength via interactions with a diverse PSD proteins, including NMDA receptors (NMDARs), AMPA receptor (AMPAR) complexes via Stargazin/TARP, adhesion molecules, as well as other scaffolding proteins, such as GKAP and Shank. PSD95 and neuronal nitric-oxide synthase (nNOS) interaction plays a role in maintaining hypersensitivity in acute and chronic pain. In addition, the assembly of the GluR6-PSD95-CaMKII complex is implicated as a majore signaling module that mediates injury induced by brain ischemia by facilitating GluR6 serine phosphorylation by CaMKII and the activation of JNK.

Neurons release and respond to brain-derived neurotrophic factor (BDNF) with bursts of brain activity. BDNF action is known to extend to peri-synaptic astrocytes, contributing to synaptic strengthening. This implies that astrocytes have a set of dynamic responses, some of which

Glutamate NMDA receptors (NMDARs) in the nucleus accumbens (NAc) are critically involved in drug dependence and reward. α2δ-1 is a newly discovered NMDAR-interacting protein that promotes synaptic trafficking of NMDARs independently of its conventional role as a calcium channel subunit.

Aberrant activation of presynaptic NMDARs in the spinal dorsal horn is integral to opioid-induced hyperalgesia and analgesic tolerance. However, the signaling mechanisms responsible for opioid-induced NMDAR hyperactivity remain poorly identified. Here, we show that repeated treatment with morphine or fentanyl
