P2Y₁₂ Receptor on the Verge of a Neuroinflammatory Breakdown

Figure 6

Regional distribution of P2Y₁₂ in proximity to MS lesions. Sections from SPMS frontal cortex were analyzed by double immunofluorescence and confocal microscopy for c-ter (red) and MHC II (green) immunoreactivity. In proximity to the demyelinating active cortical lesion expressing augmented positivity for MHC II, microglia gradually lose immunoreactivity for c-ter antibody. Microglia express differential immunoreactivity in the four chosen areas which are found inside (circled b-c) and around (circled a–d) a lesion.
