δ-Aminolevulinic acid transport through blood-brain barrier
δ-Aminolevulinic acid (ALA) and γ-aminobutyric acid (GABA) transport through the rat blood-brain barrier (BBB) was studied.GABA transport (K(m)=3.2±0.1 μM and V(max)=0.299±0.045 μmol/mg protein min) is probably mediated by a permease similar to Saccharomyces cerevisise PUT4; this result also indicat...
