The properties of the beta amino acid transport system were examined in cultivated rat brain astrocytes, using the specific probe, beta-alanine. The uptake of beta-alanine is thought to be glial specific. Beta-alanine was not actively transported and the intracellular accumulation was not altered by coincubation with GABA, alanine, glutamate, or methionine. We suggested therefore that beta-alanine is passively taken up by a mechanism distinct from the transport system for GABA.
利用特异性探针β-丙氨酸，对培养的大鼠脑星形胶质细胞中β-氨基酸转运系统的特性进行了研究。β-丙氨酸的摄取被认为具有胶质细胞特异性。β-丙氨酸不是主动转运的，与γ-氨基丁酸（GABA）、丙氨酸、谷氨酸或蛋氨酸共同孵育时，细胞内蓄积没有改变。因此我们认为，β-丙氨酸是通过一种不同于GABA转运系统的机制被动摄取的。
