WebJul 27, 2024 · Hypoxic transport inhibition is achieved by internalization of ENaC [50,51] and Na/K-ATPase . In order to examine the combined effects of hypoxia and LPS in our model, co-cultures of MΦ and rA2 and rA2-mono-cultures were treated with LPS or conditioned media from LPS-stimulated MΦ and were then exposed to hypoxia for 24 h. The epithelial sodium channel (ENaC), (also known as amiloride-sensitive sodium channel) is a membrane-bound ion channel that is selectively permeable to sodium ions (Na ). It is assembled as a heterotrimer composed of three homologous subunits α or δ, β, and γ, These subunits are encoded by four genes: SCNN1A, SCNN1B, SCNN1G, and SCNN1D. The ENaC is involved pri… bcm srl bariWebOct 16, 2024 · An alternative approach to direct ENaC inhibition is the use of indirect inhibitors, which do not directly act on ENaC but instead indirectly attenuate its function through modulation of other factors which contribute to regulation of ENaC activity.
