Polarized Amino Acid Transport by an Epithelial Cell Line of Renal Origin ( LLC-PK 1 )


The transport of D-aspartate has been studied in an epithelial cell line from a pig kidney. The amino acid is accumulated by LLC-PKI cells without evidence of metabolism. The accumulation against a concentration gradient occurs through a mechanism with several features of a carrier-mediated process. The influx may be accounted for by a saturable Na… (More)
