Fyn kinase‐mediated phosphorylation of NMDA receptor NR2B subunit at Tyr1472 is essential for maintenance of neuropathic pain
Despite abundant evidence implicating the importance of N‐methyl‐d‐aspartate (NMDA) receptors in the spinal cord for pain transmission, the signal transduction coupled to NMDA receptor activation is… Expand

Characterization of the glutamatergic system for induction and maintenance of allodynia
Glutamate is the main excitatory neurotransmitter in the central nervous system and has been shown to be involved in spinal nociceptive processing. We previously demonstrated that intrathecal (i.t.)… Expand

Attenuation of neuropathic pain by the nociceptin/orphanin FQ antagonist JTC‐801 is mediated by inhibition of nitric oxide production
At the spinal level, the involvement of nociceptin/orphanin FQ (N/OFQ) in pain transmission is controversial. JTC‐801, a selective nonpeptidergic N/OFQ antagonist, is a good tool to examine the… Expand

Cytotoxic effect of spermine on retinal pigment epithelial cells.
PURPOSE A prior study showed inactivation of ornithine-delta-aminotransferase (OAT)-deficient human retinal pigment epithelial (RPE) cells by a specific irreversible inhibitor… Expand

Pituitary Adenylate Cyclase-Activating Polypeptide Is Required for the Development of Spinal Sensitization and Induction of Neuropathic Pain
The prolonged sensitization of pain transmission after nerve injury by increasing excitability of spinal neurons and thereby promoting repair is an adaptive response of the body. The neuropeptide… Expand

Nitric oxide (NO) serves as a retrograde messenger to activate neuronal NO synthase in the spinal cord via NMDA receptors.
We have recently demonstrated that nitric oxide (NO) produced by neuronal NO synthase (nNOS) in the spinal cord is involved in the maintenance of neuropathic pain. To clarify whether NO itself… Expand

In situ measurement of neuronal nitric oxide synthase activity in the spinal cord by NADPH-diaphorase histochemistry
NADPH-diaphorase (NADPH-d) histochemistry has provided a simple method to stain neuronal nitric oxide synthase (nNOS)-containing neurons in the central nervous system. In the spinal cord, NO… Expand

Involvement of Rho-kinase in inflammatory and neuropathic pain through phosphorylation of myristoylated alanine-rich C-kinase substrate (MARCKS)
Myristoylated alanine-rich C-kinase substrate (MARCKS) is a major in vivo substrate for protein kinase C in the brain and has been implicated in cellular processes associated with cytoskeletal… Expand

A novel role of prostaglandin E2 in neuropathic pain
Neuropathic pain produced by damage to or dysfunction of the nervous system is a common and severely disabling state that affects millions of people worldwide. Recent evidence indicates that… Expand
