BV induced p38 phosphorylation in both neurons and microglia in the rat L4/5 spinal dorsal horn

(A-I) Double immunofluorescence in the dorsal horn of L4/5 spinal cord sections (16 μm) at 3 d after BV-injection, for p-p38 (green) and GFAP, an astrocyte marker (red; B, C); NeuN, a neuronal marker (red; E, F); and Iba1, a microglia marker (red; H, I) (40×). (A-C) p-p38-IR was not co-expressed with GFAP-IR. (D-F) Double immunofluorescence for p-p38 and NeuN indicated partial colocalization of p-p38 and NeuN (F, white arrow). There were many p-p38-IR cells that are not co-expressed with NeuN in the dorsal horn after BV injection (F, white arrow head). (G-I) p-p38-IR which is not co-expressed with NeuN colocalized with Iba1 (I, white arrow head). Scale bars, 50 μm (A-I).<p><b>Copyright information:</b></p><p>Taken from "Differential activation of p38 and extracellular signal-regulated kinase in spinal cord in a model of bee venom-induced inflammation and hyperalgesia"</p><p>http://www.molecularpain.com/content/4/1/17</p><p>Molecular Pain 2008;4():17-17.</p><p>Published online 30 Apr 2008</p><p>PMCID:PMC2391153.</p><p>
