Fig. 13From: Fluid and ion transfer across the blood–brain and blood–cerebrospinal fluid barriers; a comparative account of mechanisms and rolesmRNA expression relative to that of the Na+/H+-exchanger, NHE1, in rat brain endothelial cells, choroid plexus and kidney cortex. At the blood–brain barrier expression of mRNAs for anion exchangers 2 and 3, AE2 and AE3, the Na+/H+-exchanger, NHE1, the charge-transporting Na+, HCO3 −-cotransporter, NBCe1 and the neutral Na+, HCO3 −-cotransporter, NBCn1, are prominent. Those for the Cl−-dependent Na+, HCO3 −-cotransporters, NCBE/NBCn2, and NDCBE are clearly detected. Redrawn from data in [336]Back to article page
