title: Effect of IL-15 on the secretion of IL-1beta, IL-1Ra and sIL-1RII by PMN from cancer patients.
abstract: In the present study, we demonstrate an effect of rhIL-15 on the simultaneous secretion of IL-1beta and its natural inhibitors IL-1Ra and sIL-1RII by human neutrophils isolated from normal and tumour-bearing hosts (oral cavity cancer and melanoma patients) compared with serum IL-15 levels. We found an rhIL-15 influence on IL-beta and IL-1Ra secreted by PMN from healthy controls. In contrast, the PMNs from cancer patients were not sensitive to rhIL-15 stimulation. However, we found a priming effect of rhIL-15 on IL-1beta production by LPS-stimulated cells in oral cavity cancer. We also found no effect on sIL-1RII release by PMN from cancer patients.
