Abstract

β₂-Adrenergic agonists have been shown to regulate Na,K-ATPase in the alveolar epithelium by recruiting Na,K-ATPase-containing vesicles to the plasma membrane of alveolar epithelial cells (AEC). Here, we provide evidence that β₂-agonists induce store-operated calcium entry (SOCE) in AECs. This calcium entry is necessary for β₂-agonist-induced recruitment of Na,K-ATPase to the plasma membrane of AECs. Specifically, we show that β₂-agonists induce SOCE via stromal interaction molecule 1 (STIM1)-associated calcium release-activated calcium (CRAC) channels. We also demonstrate that the magnitude of SOCE affects the abundance of Na,K-ATPase at the plasma membrane of AECs.
