Following systemic injection, several different dyes and markers are found to accumulate rapidly in cells in the arcuate nucleus and median eminence, and the capillaries in this region appear specialised for exchange of molecules. The present study used hydroxystilbamidine (FluoroGold equivalent) to identify cells that take up molecules from the circulation in these regions; 2-6 h following injection, uptake was seen in the external and intermediate zones of the median eminence and the adjacent… CONTINUE READING
