Carrier-mediated transport of amino acids through the blood-retinal and the blood-brain barriers

  • P. Törnquist
  • A. Alm


The uptake-index method was used to study the transport of amino acids through the blood-retinal and blood-brain barriers in rats. The results indicate the existence of at least two different, similar carriers in both barriers, i.e., one each for neutral and basic amino acids. A third separate transport system for taurine was found in the blood-retinal barrier. All of the carrier systems studied transported amino acids from blood to nervous tissue.
