The evaluation of TSPO expression was assessed with immunohistochemistry at different magnifications in the contralateral hemisphere and the core of the infarction, as represented in the co-registered [18F] VUIIS1008 PET-MRI T2W image at day 7 after cerebral ischemia (20×*, 20×** and 100×**, Fig. 7a). Here, TSPO is linked to brain ischemia.
