Nov 15, 2015 This data reveal an activation of plasma membrane mechanism of H + extrusion under chloroquine treatment.” “We have previously shown that the acidic pool also functions as a Ca 2+ store in permeabilized malaria parasites and that chloroquine causes Ca 2+ release from this store Passos & Garcia 1998.
