Abstract:
:Amiloride is a prototypic inhibitor of epithelial sodium channels. Rapid progress has been made in our understanding of the structure of the sodium channel and related cation-selective channels. This work, coupled with experiments examining how selected sodium channel mutations affect amiloride binding, provides critical clues towards defining sites within the channel that bind amiloride. Residues within the channel pore and within its extracellular domain participate in amiloride binding. These results suggest that sites that interact with amiloride within the channel's extracellular domain may be in close proximity to residues within the channel's pore.

杂志文章,评审abstract::Compelling evidence points to a role for IgA receptors in the pathogenesis of IgA nephropathy. The soluble form of the type I IgA receptor (FcalphaRI or CD89) forms complexes with IgA that can be found in patients' serum and that initiate the disease in CD89 transgenic mice. A nonclassic IgA receptor, identified as th...
