Figure 4From: Injury induced activation of extracellular signal-regulated kinase (ERK) in the rat rostral ventromedial medulla (RVM) is age dependant and requires the lamina I projection pathway Intrathecal injection of SSP-SAP reduces NK1 receptor expression in the superficial dorsal horn. Effect of SSP-SAP or saline intrathecal injections on NK1 receptor expression in the superficial dorsal horn. A, B/Confocal images of NK1 receptor immunohistochemistry in lamina I of SNI animals after SSP-SAP or saline treatment. C,D/Confocal images of NK1 receptor immunohistochemistry in lamina III of SNI animals after SSP-SAP or saline treatment. All images taken from the dorsal horn. contralateral to SNI. Arrows show cell bodies within lamina III. Scale bar, 100 ÎĽm.Back to article page
