title: The uptake of anionic and cationic amino acids by the isolated perfused sheep choroid plexus.
abstract: The carrier-mediated uptake of anionic and cationic amino acids by the basolateral face (blood side) of the isolated perfused sheep choroid plexus was demonstrated using the paired-tracer dilution technique. The uptake of these two classes of amino acid was higher than at the blood-brain barrier with no cross-competition between them. In addition the uptake was markedly stereospecific with a high degree of selectivity and no interaction with the L-system amino acids.
