1 We now report that BALB/cJ BMMC stimulated with KL + IL-10 + IL-1beta also exhibit the biphasic release of [3H]arachidonic acid with an immediate phase over the first 10 min followed by a delayed phase from 2 to 7 h. The delayed phase of arachidonic acid release and of PGD2 generation was inhibited by heparin, which concomitantly released a phospholipase (PL) A2 from the cells into the supernatant. Arachidonic Acid interleukin 1 beta Mus musculus
