1 The effect of Granulocyte-Macrophage, Colony Stimulating Factor (GM-CSF) and Interleukin-6 (IL-6) on leukotriene production by CML white blood cells induced by calcium ionophore (A23187) was investigated and the leukotrienes formed were identified and quantified using high performance liquid chromatography (HPLC).

2 Although GM-CSF or IL-6 alone did not stimulate the synthesis of 5-lipoxygenase product, preincubation of the white blood cells of CML with GM-CSF or IL-6 for 30 minutes at 37 degrees C enhanced the ionophore A23187 induced leukotrienes synthesis, thus the CML white blood cell suspension primed with GM-CSF or IL-6 produced 26.6 +/- 2.8 and 18.9 +/- 1.3 pmol LTC4/10(6) cells respectively, and 30.2 +/- 3.6 and 25.5 +/- 2.5 Pmol LTB4/10(6) cells.
