Fig. 4From: Inhibition of mast cell tryptase attenuates neuroinflammation via PAR-2/p38/NFκB pathway following asphyxial cardiac arrest in ratsCellular co-localization of PAR-2 in microglia. Representative double immunofluorescence staining images at 24 h following ACA showed that PAR-2 (red) co-localized with Iba-1 positive microglia (green) in both sham and ACA groups (white arrows). Top panel indicates the location of staining (small red box). Scale bar = 50 μm, n = 1/groupBack to article page
