Abstract
We investigated the mRNA levels of interleukin-6-related genes in a rat dorsal root ganglion after application of a tourniquet to a hind limb in order to identify the molecules that are induced immediately after peripheral nerve injury at the early stage. Induction of interleukin-6 and upregulation of glycoprotein 130 mRNA expressions were observed in the ipsilateral dorsal root ganglion at 4 h after tourniquet application. Interleukin-6 protein was detected in small-sized and medium-sized dorsal root ganglion cells by immunohistochemical analysis. The induction of interleukin-6 expression is likely to play a role in the protection of injured neurons perhaps related to growth of their axons. Glycoprotein 130 might also account for the inhibitory effects following nerve injury.
