Immune-mediated nerve inflammation is involved in many painful states in humans, and causes axonal and behavioral changes in rats. While models of nerve inflammation have been characterized using electrophysiological and behavioral methods, the presence of immune cells has not been fully assessed. We inflamed rat sciatic nerves using complete Freund's adjuvant and quantified the presence of ED-1 macrophages and TCR-αβ T-cells for up to 12 weeks. We report that these immune cells are prominent extraneurally up to 12 weeks following the induction of inflammation. This observation does not easily correlate with inflammation-induced axonal mechanical sensitivity, which peaks within 1 week and is resolved after 8 weeks.
