Abstract :
[en] Extracellular ATP, acting at P2Y and P2X receptors, has recently been shown to contribute to airway inflammation. Using different epithelial cell models, this study shows that ATP promotes TNF-alpha-elicited IL-8 expression through P2X ion channel-triggered Ca(2+) entry, leading to CaMK-dependent IKK activation and binding of active p65 to IL-8 gene promoter.
