it is concluded that ( i ) endotoxin shed from e. coli ( killed or live ) may be one factor mediating the pmnl infiltration induced by this organism , ( ii ) endotoxin probably acts independent of in vivo complement activation , ( iii ) the activity is dependent on the lipid a moiety , and ( iv ) antibody binding to o or core glycolipid antigens can modify endotoxin so as to diminish its capacity to induce pmnl infiltration in vivo .
