Figure 4From: Behavioral evidence for the differential regulation of p-p38 MAPK and p-NF-κB in rats with trigeminal neuropathic pain Double immunofluorescent staining of p-p38 MAPK. P-p38 MAPK (red) immunoreactive cells were found to mainly co-localize with OX42 (green), but not NeuN (green) or GFAP (green) in the rat medullary dorsal horn following inferior alveolar nerve injury.
