Abstract:
:Pathways for transfer of horseradish peroxidase (HRP) across the cerebral microvasculature were studied in Mongolian gerbils after inducing either unilateral carotid-artery ligation or intracarotid air embolism. Electron microscopy on samples from both ipsilateral and contralateral brain hemispheres showed the reaction product (HRP) in the endothelial cytoplasm of capillaries and arteriols in all animals; in the basal lamina, HRP was seen only after long (3--4 h) ischemic periods. HRP was seen within both spherical and tubular structures, with the latter appearing in obliquely or longitudinally sectioned blood vessels. These endothelial channel-like structures are part of a tubulovesicular network which seemingly exists in the normal endothelium of the gerbil brain. The tubules serve as pathways for proteins into the brain; protein transfer becomes enhanced following circulatory injuries such as ischemia.
