CXCL13 is a B lymphocyte chemoattractant and activates CXCR5 receptor in the immune system. Here we investigated whether CXCL13/CXCR5 mediates inflammatory pain in dorsal root ganglia (DRG) and the underlying mechanisms. Peripheral injection of complete Freund's Adjuvant (CFA) increased the expression of CXCL13 and CXCR5 in DRG neurons. In Cxcr5-/- mice, CFA-induced pain hypersensitivity were a...

We describe the case of a patient with aseptic meningoencephalitis after intrathecal iohexol injection for myelography and review the previous literature on similar cases of contrast-induced neurotoxicity.

cell therapy is known as one of the most promising curative interventions in the spinal cord injury (sci). selection of an appropriate route to transplant the stem cells is very important. principally, four different injection routes have been used in animal experiments. 1. intramedullary route: this route is known as a classic method for transplantation of stem cells. in this method, the stem ...

Glutamate is a major excitatory neurotransmitter in primary afferent terminals and is critical for normal spinal excitatory synaptic transmission. However, little is known about the regulation of synaptically released glutamate in the spinal cord under physiologic conditions. The sodium-dependent, high-affinity glutamate transporters are the primary mechanism for the clearance of synaptically r...

BACKGROUND Effective early antiviral treatments reduce both acute zoster pain and the risk of postherpetic neuralgia. The authors hypothesized that the direct neuraxial administration of acyclovir could provide superior drug application to the spinal neural structures with a higher viral burden and have various advantages over the other routes of drug administration in terms of required doses, ...

Abnormal histone acetylation occurs during neuropathic pain through an epigenetic mechanism. Silent information regulator 1 (sir2 or SIRT1), a NAD-dependent deacetylase, plays complex systemic roles in a variety of processes through deacetylating acetylated histone and other specific substrates. But the role of SIRT1 in neuropathic pain is not well established yet. The present study was intende...

To determine whether intracerebrally localized iodothyronines produce thyroid hormone-related functional effects, heart rate responses were compared in conscious hypothyroid rats given triiodothyronine (T3) by either the intrathecal or the intravenous route. A significant increase in heart rate occurred within 18 h after 1.5 amol T3/100 g body wt was delivered intrathecally through a cannula pr...
