Abstract excerpt
TNF-alpha induced an increase in intercellular adhesion molecule-1 (ICAM-1) expression in human A549 epithelial cells and immunofluorescence staining confirmed this result. The enhanced ICAM-1 expression was shown to increase the adhesion of U937 cells to A549 cells. Tyrosine kinase inhibitors (genistein or tyrphostin 23) or phosphatidylcholine-specific phospholipase C (PC-PLC) inhibitor (D 609) attenuated...
