COX-2 immunoreactivity in MS spinal cord is in microglial cells/macrophages. (A) Autoradiographic localisation of 3 [H] PK11195 in a spinal cord from a patient with MS, co-located with CD68 (D) (Scale bars = 1000 μm). The square indicates the area where subsequent CD68 and COX-2 images were taken from. B) And E) Microglial cell/macrophage-like immunostaining with CD68 antibody (Scale bars = 200 μm and 100 μm respectively). C) And F) Microglial cell/macrophage-like immunostaining with COX-2 (Scale bars = 200 μm and 100 μm respectively).
