Co-localization of A
receptors with microglial cells (IBA1) in white matter of SC 24 h after injury. Double immunofluorescence was used to characterize the co-localization of A2A receptors (in red with Texas red) with microglia (in green with fluorescein) in sham-operated and SCI mice groups. The merged images show that A2A receptors are not present on activated microglial cells of the SC. The drawing under figures shows that A2A receptors were identified in the white matter area as indicated by arrow. Scale bar = 10 μm.
