The brain efflux index method is used to examine the extent to which transferrin effluxes from brain to blood across the blood-brain barrier (BBB) following intracerebral injection. Whereas high-molecular-weight dextran is nearly 100% retained in brain for up to 90 min after intracerebral injection in the Par2 region of the parietal cortex of brain, there is rapid efflux of transferrin from brain to blood across the BBB. The efflux of apotransferrin is 3.5-fold faster than the efflux of holo-transferrin. The brain to blood efflux of apotransferrin is completely saturable by unlabeled transferrin, but is not inhibited by other plasma proteins. These studies provide evidence for reverse transcytosis of transferrin from brain to blood across the BBB. As circulating transferrin is known to undergo transcytosis across the BBB in the blood-to-brain direction, these studies support the model of bidirectional transcytosis of transferrin through the BBB in vivo.
