Recently it has been shown that mast cells, through release of their pro-inflammatory mediators, are involved in aspirin attacks in aspirin-sensitive patients. To date, little information is available concerning 8-isoprostane (8-epi-prostaglandin F) production by mast cells. Therefore, we examined whether exposure of mast cells to aspirin can lead to isoprostane production. In this study we show that in mast cells, IgE and antigen stimulates an intracellular oxidative burst inducing H2O2 and 8-epi-PGF production. Moreover, we show that exposure of mast cells to aspirin directly induces the production of 8-epi-PGF. Our study suggests that production of 8-epi-PGF by mast cells could contribute to the inflammatory response in e.g. aspirin-sensitive asthma patients.
