Fig. 5From: [18F]FEPPA PET imaging for monitoring CD68-positive microglia/macrophage neuroinflammation in nonhuman primatesmCherry (a–c) and CD68 immunostained (d–f) brain tissue sections counterstained with Nissl from the hemiparkinsonian monkey R4 with unilateral allogeneic grafts in the postcommisural putamen. Images a, c and d, f correspond to higher magnification of the squares in coronal brain sections b and e respectively. Insets a1, c1, d1, and f1 are higher magnification of the square in panels a, c, d, and f respectively. Scale bars: d, 1 mm; e, 10 mm; d1, 50 μmBack to article page
