In neutrophils, binding and phagocytosis facilitate subsequent intracellular killing of microorganisms. Activity of Na+/H ÷ exchangers (NHEs) participates in these events, especially in regulation of intracellular pH (pHi) by compensating for the H ÷ load generated by the respiratory burst. Despite the importance of these functions, comparatively little is(More)
The protective effects of retinoic acid on elastase-induced lung epithelial cell injury were studied using elastase extracted from purulent human sputum, the BEAS-2B human bronchial epithelial cell line, A549 human type II lung cell line, and primary cultures of human tracheal epithelial cells. Elastase decreased viability of BEAS-2B cells, A549 cells, and(More)
