mRNA expression of the α₂-adrenergic and 5-HT₇ receptors in the ipsilateral lumbar dorsal horn and dorsal root ganglia (DRG) from early- and late-phase monoiodoacetate (MIA) animals (early phase, n = 4; early phase sham; n = 4; late phase, n = 4; late phase sham, n = 4). A: in the dorsal horn, there was no significant change in mRNA expression levels of the α₂-adrenergic or 5-HT₇ receptors between groups (Kruskal-Wallis). B: in the L3–L5 DRG, there was no significant change in mRNA expression levels of the α₂-adrenergic or 5-HT₇ receptors between groups (Kruskal-Wallis).
