1 The aim of this study was to evaluate the effects of TK and PI3-K inhibitors on basophil histamine release induced by anti-IgE, IL-3 and GM-CSF. Histamine interleukin 3 Homo sapiens
2 Since IL-3 and GM-CSF cause histamine release from normal human basophils only when the inhibitory effect of extracellular Na(+) has been removed, peripheral blood leukocytes were suspended in isotonic solutions containing either 140 mM NaCl or 140 mM N-methyl-D-glucamine(+). Histamine interleukin 3 Homo sapiens
3 AG-126, genistein and lavendustin A exerted a significant dose-dependent inhibitory effect on basophil histamine release induced by anti-IgE (either in high or in low Na(+) medium), IL-3 and GM-CSF. Histamine interleukin 3 Homo sapiens
4 Tyrphostin 51 caused a weak inhibition of histamine release induced by IL-3, GM-CSF and anti-IgE in a low Na(+) medium, but not in a physiological Na(+)-containing medium. Histamine interleukin 3 Homo sapiens
5 These results suggest a possible role of TK and PI3-K in basophil histamine release induced by anti-IgE, IL-3 and GM-CSF. Histamine interleukin 3 Homo sapiens
