Dorsal root ganglion - a potential new therapeutic target for neuropathic pain

J Pain Res. 2012;5:31-8. doi: 10.2147/JPR.S26603. Epub 2012 Feb 16.

Abstract

A regional approach can protect our patients from often unacceptable adverse effects produced by systematically applied drugs. Regional therapeutic approaches, as well as interventions at the level of the peripheral nervous system and particularly the dorsal root ganglion (DRG), represent an alternative to the systemic application of therapeutic agents. This article provides an overview of DRG anatomical peculiarities, explains why the DRG is an important therapeutic target, and how animal models of targeted drug delivery can help us in the translation of basic research into clinical practice.

Keywords: dorsal root ganglion; neuropathic pain; pain therapy; targeted drug delivery.
