Abstract Ascorbic acid (vitamin C) accumulation in activated human neutrophils is increased as much as 10-fold above the mM concentrations present in normal neutrophils. Internal concentrations as high as 14 mM are achieved when external vitamin is at physiologic concentration. The mechanism is by oxidation of external vitamin to dehydroascorbic acid, preferential transmembrane translocation of dehydroascorbic acid, and intracellular reduction to ascorbic acid within minutes. These data indicate that vitamin C accumulation is enhanced in activated human neutrophils and that human neutrophils utilize and recycle oxidized external vitamin C under physiologic conditions.
