Representative high-power confocal double immunofluorescence images reveal expression of COX2 (green) in CD68-positive cells (red), a marker for activated monocyte-derived cells (A–C), and in von Willebrand factor (vWF)-positive endothelial cells (D–F) in the brain of a monkey with aquired immunodeficiency syndrome and encephalitis. Single immunofluorescence images (green and red) are merged (yellow; C, F). Scale bars = (A–F) 10 µm.
