title: ATP-dependent Cl- uptake by plasma membrane vesicles from the rat brain.
abstract: Uptake of Cl- by plasma membrane vesicles from the rat brain was stimulated by ATP at 37 degrees C, but not by beta, gamma-methylene ATP or at 0 degrees C. The addition of Triton X-100 or sucrose to the incubation medium diminished the ATP-stimulated Cl- uptake, suggesting that Cl- was transported across the membranes into the intravesicular space. This ATP-stimulated Cl- uptake was not affected by 1 mM ouabain. 1 microM oligomycin, 0.1 mM gamma-aminobutyric acid or 0.1 mM picrotoxin. Thus, non-mitochondrial ATP-driven Cl- transport through a system other than Na, K-ATPase or Cl- channels occurs in neuronal plasma membrane vesicles.
