1 Reduced priming effect of interleukin 3 on IgE mediated basophil histamine release in patients with systemic sclerosis. Histamine interleukin 3 Homo sapiens
2 OBJECTIVE: To determine the capacity of interleukin 3 (IL-3) to induce and enhance basophil histamine release in patients with systemic sclerosis (SSc). Histamine interleukin 3 Homo sapiens
3 The priming effect of IL-3 on anti-IgE and fMLP induced histamine release was evaluated. Histamine interleukin 3 Homo sapiens
4 IL-3 was a weak basophil agonist in both populations, since net histamine release did not exceed 10% of total histamine content in any case. Histamine interleukin 3 Homo sapiens
5 IL-3 was a weak basophil agonist in both populations, since net histamine release did not exceed 10% of total histamine content in any case. Histamine interleukin 3 Homo sapiens
6 IL-3 enhanced anti-IgE and fMLP induced histamine release in a dose dependent fashion. Histamine interleukin 3 Homo sapiens
7 However, the enhancement of anti-IgE induced histamine release by IL-3 was significantly lower in patients with SSc than in controls (p < 0.01 at 0.1 ng/ml IL-3; p < 0.05 at 1 and 10 ng/ml IL-3). Histamine interleukin 3 Homo sapiens
8 However, the enhancement of anti-IgE induced histamine release by IL-3 was significantly lower in patients with SSc than in controls (p < 0.01 at 0.1 ng/ml IL-3; p < 0.05 at 1 and 10 ng/ml IL-3). Histamine interleukin 3 Homo sapiens
9 However, the enhancement of anti-IgE induced histamine release by IL-3 was significantly lower in patients with SSc than in controls (p < 0.01 at 0.1 ng/ml IL-3; p < 0.05 at 1 and 10 ng/ml IL-3). Histamine interleukin 3 Homo sapiens
10 CONCLUSION: Basophil response to anti-IgE and the priming effect of IL-3 on IgE mediated basophil histamine release are lower in patients with SSc than in controls. Histamine interleukin 3 Homo sapiens
