In the DCT, sodium balance is primarily determined by the regulation of the sodium-chloride cotransporter (NCC). When phosphorylated, NCC reabsorbs sodium away from the lumen of the nephron. Dephosphorylation of NCC inactivates this reabsorption resulting in increased sodium excretion. A similar effect is leveraged by a common class of anti-hypertensive medications called thiazides, which block NCC activity. Gaining a better understanding of the molecular mechanism by which NCC is regulated holds high clinical relevance to several diseases including hypertension, FHHt, and Gitelman syndrome. To investigate a novel mechanism that may regulate NCC activity, we implemented a cell-specific chemogenetic approach with Designer Receptors Exclusively Activated by Designer Drugs (DREADD) technology.}, number = {IR}, doi = {https://doi.org/10.6083/rj430538n}, recid = {9559}, address = {2022-04-08}, }
