Fig. 6From: Inhibition of peripheral macrophages by nicotinic acetylcholine receptor agonists suppresses spinal microglial activation and neuropathic pain in mice with peripheral nerve injurySuppressive effects of peripheral nAChR agonists on upregulation of microglial molecules in the SDH after PSL. Mice were subject to PSL or sham surgery. TC-2559 or sazetidine A was administered (p.n., 20 nmol) on days 0, 1, 2, and 3, and the lumbar SDH (L4–5) was collected. Expression levels of Iba1, CD11b, CD68, IRF5, IRF7, IL-1β, and CCL3 mRNA on day 7 after PSL were analyzed by RT-qPCR. Data are presented as the mean ± SEM; n = 6–7. ***P < 0.001, **P < 0.01 versus sham. ##P < 0.01, #P < 0.05 versus PSL/VehBack to article page
