In fact, the mean of the [3H]AA released after GM-CSF challenging from CF neutrophils was markedly lower in comparison to that from CT cells (GM-CSF: CF vs CT: P < 0.02).There were no differences in either [14C]DHA or [3H]AA release between CF patient with (n = 8) and without (n = 7) diabetes. This evidence concerns the gene CSF2 and diabetes mellitus.
