1 Pharmacologic study of basophil histamine release induced by monocyte chemotactic protein-1 with kinase inhibitors. Histamine C-C motif chemokine ligand 2 Homo sapiens
2 In this study, we examined the effect of a panel of kinase inhibitors on MCP-1-induced histamine release from human basophils to characterize the signaling pathway used by this chemokine. Histamine C-C motif chemokine ligand 2 Homo sapiens
3 Genistein (3 micrograms/ml), an inhibitor of tyrosine kinase, inhibited MCP-1-induced histamine release by 44%. Histamine C-C motif chemokine ligand 2 Homo sapiens
4 It blocked MCP-1-induced histamine release with an IC50 of 3.3 x 10(-8) M indicating a role of PI-3 kinase in this reaction. Histamine C-C motif chemokine ligand 2 Homo sapiens
5 KT5926, an inhibitor of myosin light chain kinase, also inhibited histamine release in response to MCP-1 with an IC50 of 10(-6) M. Staurosporine, a potent inhibitor of protein kinase C, although being not specific, augmented MCP-1-induced histamine release by 31.9% at 10(-6) M. These results indicate the possible involvement of a series of kinases, including PI-3 kinase, in the signal transduction pathway used by MCP-1. Histamine C-C motif chemokine ligand 2 Homo sapiens
