CHPG is a selective, potent mGluR5 agonist. CHO cells expressing mGluR5 (but not those expressing mGluR1) are activated by CHPG. In vivo, CHPG stimulates thalamic neurons and is antagonized by MPEP (selective mGluR5 antagonist); CHPG potentiates NMDA and AMPA responses in spinal cord and produces oscillations in intracellular calcium in dorsal root ganglion cells.
Glutamate is one of the major excitatory neurotransmitters of the CNS and is essential for numerous key neuronal functions. However, excess glutamate causes massive neuronal death and brain damage owing to excitotoxicity via the glutamate receptors. Metabotropic glutamate receptor 5

Acetylcholine (ACh) signaling is involved in a wide range of processes, including arousal, attention, and learning. An increasing number of studies indicate that cholinergic control of these functions is highly deterministic, mediated by synaptic afferents that generate reliable and precise
Peripheral tissue inflammation or injury causes glutamate release from nociceptive axons, keratinocytes, and Schwann cells, resulting in thermal hypersensitivity. However, the detailed molecular mechanisms underlying glutamate-induced thermal hypersensitivity are unknown. The aim of this study was to clarify the involvement
Reticulons (RTNs) are a group of membrane-bound proteins that are dominantly localized to the endoplasmic reticulum (ER). RTN1-C, one isoform of RTNs highly expressed in the brain, has been shown to mediate neuronal injury in cerebral ischemia models. The aim

The hippocampus is a key brain region for memory formation. Metabotropic glutamate type 5 receptors (mGlu5R) are strongly expressed in CA1 pyramidal neurons and fine-tune synaptic plasticity. Accordingly, mGlu5R pharmacological manipulation may represent an attractive therapeutic strategy to manage hippocampal-related
