1 Granulocyte-macrophage colony-stimulating factor and interleukin-3 cause basophil histamine release by a common pathway: downregulation by sodium. Histamine interleukin 3 Homo sapiens
2 Granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3) are recognized as enhancers, but not as inducers, of histamine release from normal human basophils. Histamine interleukin 3 Homo sapiens
3 Granulocyte-macrophage colony-stimulating factor (GM-CSF) and interleukin-3 (IL-3) are recognized as enhancers, but not as inducers, of histamine release from normal human basophils. Histamine interleukin 3 Homo sapiens
4 However, when extracellular Na+ is removed IL-3 acquires the capacity to induce histamine release. Histamine interleukin 3 Homo sapiens
5 However, when extracellular Na+ was substituted iso-osmotically with N-methyl-d-glucamine+ or with choline+, GM-CSF and IL-3 were able to trigger histamine release from either mixed leucocyte suspensions or purified human basophils. Histamine interleukin 3 Homo sapiens
6 The kinetics of IL-3-induced histamine release were similar, whereas anti-IgE-induced histamine release was more rapid, being almost maximal after incubation for 30 min. Histamine interleukin 3 Homo sapiens
7 A good correlation was found between GM-CSF-induced and IL-3-induced histamine release; furthermore, the combined effects of the two cytokines were less than additive, suggesting that they share the same pathways leading to histamine release. Histamine interleukin 3 Homo sapiens
8 When extracellular Na+ concentration was increased from 0 to 140 mm, histamine release induced by GM-CSF, IL-3 and anti-IgE was reduced progressively. Histamine interleukin 3 Homo sapiens
9 These results provide indirect evidence that GM-CSF and IL-3 can induce basophil histamine release by a common pathway that is downregulated by Na+. Histamine interleukin 3 Homo sapiens
