Immunohistochemical detection of CD163. (a-c) a- PVM immunoreactive for CD163 in the frontal cortex of a control case. b- Parenchymal microglia immunoreactive for CD163 in the occipital cortex of an AD case. c- CD163 immunoreactive microglia in close proximity to meningeal spaces in the occipital lobe of an AD case. (d-f) Range of CD163 immunoreactivity (based on %area) in microglia from d-mild, e-moderate, to f-severe.
