Fig. 3.
Ischemia, neuroinflammation and NMDAR distribution 30 days after MCAO.
A = Infarction (hyperintense area) shown by T2W-MRI, B =cresyl violet stained section C= Distribution of PBR labeled with [3H] PK11195, D= Distribution of NMDAR labeled with [3H] MK801, E = Non-specific binding of [3H] MK801 in the presence of excess unlabeled MK801, same anatomical level as A-D. Autoradiograms were pseudocolored using the rainbow spectrum, Max = Maximum and MIN = Minimum.
Normal distribution patterns of PBR and NMDAR are illustrated in figure 2 above. Note the presence of atrophy in the ipsilateral hemisphere at this late time point (enlarged ventricle and smaller area of the ipsilateral hemisphere), with a persistent intense increase in PBR and persistent decrease in NMDAR which is most pronounced in areas of the ipsilateral cortex where PBR density is highest.
