we show by northern blot analysis and bioassays that pmn can be induced to accumulate mrna specific for il-1 alpha and il-1 beta indistinguishable in size from il-1 mrna synthesized by activated human macrophages and consequently to release il-1-like activity in their culture supernatants , that could be neutralized by a mab to il-1 .
