1 Renal expression of osmotically responsive cation channel TRPV4 is restricted to water-impermeant nephron segments. Water transient receptor potential cation channel subfamily V member 4 Homo sapiens
2 Therefore, TRPV4 is expressed in only those nephron segments that are constitutively (i.e., ATL, TAL, and DCT) or conditionally (i.e., collecting duct) water impermeant and where generation of a substantial transcellular osmotic gradient could be expected. Water transient receptor potential cation channel subfamily V member 4 Homo sapiens
3 TRPV4 expression is absent from nephron segments exhibiting constitutive water permeability and unregulated apical aquaporin expression (i.e., PT and DTL). Water transient receptor potential cation channel subfamily V member 4 Homo sapiens
