Full text not available from this repository. (Request a copy)Human neutrophils undergo autophagic-like cell death following Sialic acid binding immunoglobulin-like lectin-9 (Siglec-9) ligation and concurrent stimulation with certain, but not all, neutrophil survival cytokines. Caspase inhibition by these cytokines is required, but is not sufficient, to trigger this particular form of cell death. Additional mechanisms may involve reactive oxygen species (ROS), and blocking of ROS or prevention of ROS production prevents autophagic-like neutrophil death. Interestingly, human intravenous immunoglobulin (IVIg) preparations contain natural anti-Siglec-9 autoantibodies, which are able to ligate Siglec-9 on neutrophils and induce autophagic-like cell death in the presence of granulocyte-macrophage colony-stimulating factor (GM-CSF) and some other survival cytokines. Here, we discuss the pathophysiological and therapeutic implications of these recent findings.
