Microvascular pericytes take up ascorbic acid on the ascorbate transporter SVCT2. Intracellular ascorbate then protects the cells against apoptosis induced by culture at diabetic glucose concentrations. To investigate whether pericytes might also provide ascorbate to the underlying endothelial cells, we studied ascorbate efflux from human pericytes. When loaded with ascorbate to intracellular concentrations of 0.8-1.0 mM, almost two-thirds of intracellular ascorbate effluxed from the cells over… Expand
Vitamin C Transporters in Cancer: Current Understanding and Gaps in Knowledge
TLDR
An overview of the current, limited knowledge of ascorbate transport across membranes, as well as tissue distribution, gene expression, and the relevance of SVCTs in cancer is given. Expand
Ascorbate in the Apoplast: Metabolism and Functions
Abstract Ascorbic acid (AA) is one of the most important antioxidants and redox-active substances of plants found in the apoplast. In the form of ascorbate anion, it can be exported to the cell wallExpand
How does Ascorbate Improve Endothelial Dysfunction? - A Computational Analysis.
TLDR
Detailed understanding of the mechanism responsible and the optimal cellular Asc levels for improvement in endothelial dysfunction is provided and Asc supplementation may be used as an effective therapeutic strategy when BH4 levels are depleted. Expand
NEUROBIOLOGY OF VITAMIN C: EXPANDING THE FOCUS FROM ANTIOXIDANT TO ENDOGENOUS NEUROMODULATOR.
TLDR
It is suggested that improved understanding of the regulation of endogenous AA and its interaction with key brain neurotransmitter systems, rather than administration of AA in excess, should be the target of future brain-based therapies. Expand

TLDR
Assayed the antioxidant activities of SCA and NDA using ABTS radical cation and their neurite outgrowth-enhancing activities in PC12 cells indicated that SCA has antioxidant activity and thatSCA andNDA have neuriteOutgrowth- enhancing activity. Expand

Ascorbic acid transport in brain microvascular pericytes.
TLDR
The data clarify previous inconsistencies in the literature, implicate SVCT2 as the pericyte ascorbate transporter, and show that pericytes are capable of concentrating intracellular asCorbate against a gradient in an energy- and sodium-dependent fashion. Expand
Ascorbic acid efflux and re-uptake in endothelial cells: maintenance of intracellular ascorbate

TLDR
Results support the hypothesis that ascorbate efflux reflects trans-endothelial cell asCorbate movement out of the blood vessel, and suggest that efflux of the vitamin was countered in part by its re-uptake on ascorBate transporters. Expand
Ascorbate Transport and Recycling by SH-SY5Y Neuroblastoma Cells: Response to Glutamate Toxicity
TLDR
The mechanisms by which neuronal cells in culture transport and maintain ascorbate, as well as how this system responds to oxidant stress induced by glutamate are studied, showing absence of heteroexchange. Expand
Development of ascorbate transporters in brain cortical capillary endothelial cells in culture
TLDR
Although the SVCT2 is induced by culture of cortical capillary endothelial cells, its absence in vivo remains perplexing, given the need for intracellular ascorbate to facilitate type IV collagen maturation and release by endothelial Cells. Expand
Ascorbate Transport and Intracellular Concentration in Cerebral Astrocytes
TLDR
Results indicate that uptake and efflux pathways are stimulated by cyclic AMP‐dependent mechanisms and that they regulate the cytosolic concentration of ascorbate in astrocytes. Expand
Ascorbic acid prevents high glucose-induced apoptosis in human brain pericytes.
TLDR
Results show that ascorbate prevents pericyte apoptosis due RAGE activation, which may involve effects beyond its function as an antioxidant as well as evidence of increased oxidative stress. Expand
Osmotic Swelling Stimulates Ascorbate Efflux from Cerebral Astrocytes
TLDR
Ascorbate release during astrocytic swelling may contribute to cellular osmoregulation in the short‐term and the scavenging of reactive oxygen species. Expand
Efflux of hepatic ascorbate: a potential contributor to the maintenance of plasma vitamin C.
TLDR
Results show that hepatocytes take up and reduce DHA and subsequently release part of the AH formed, probably via a membrane transporter, suggesting that the liver might contribute to the maintenance of plasma AH, a process that could be important under conditions of oxidative stress. Expand
Ascorbic acid transport in mouse and rat astrocytes is reversibly inhibited by furosemide, SITS, and DIDS
TLDR
The uptake ofL-ascorbic acid by astrocytes was studied using primary cultures prepared from the neopallium of newborn Swiss CD-1 mice or Sprague-Dawley rats and the rapid and reversible effects of the impermeant inhibitors (SITS and DIDS) are consistent with direct inhibition of ascorbate transporters located in the astroglial plasma membrane.

Protection and Recycling of α-Tocopherol in Human Erythrocytes by Intracellular Ascorbic Acid
Abstract Ascorbic acid can recycle α-tocopherol from the tocopheroxyl free radical in lipid bilayers and in micelles, but such recycling has not been demonstrated to occur across cell membranes. InExpand
