TSPO PET detects acute neuroinflammation but not diffuse chronically activated MHCII microglia in the rat

ConclusionTSPO was only expressed in the stroke-induced insult and proximal tissue and therefore was unable to detect remote and non-insult-related chronically activated microglia overexpressing MHCII in WM. This suggests that research in neuroinflammation, particularly in the WM, would benefit from MHCII-sensitive radiotracers.
