role in these responses include a group of protein kinases with homology to the yeast Ste20 protein (PAK kinases), the WiskettAldrich syndrome protein (WASP), and phosphatidylinositol-3-kinase (PI3-kinase) (20) .. PI3kinase is unlikely to playa role in S. typhimurium-induced signaling, however, as wortmannin, a potent inhibitor of PI3kinase, has no effect on the S. typhimurium-' induced cell re...
