1 Mechanism of Siglec-8-mediated cell death in IL-5-activated eosinophils: role for reactive oxygen species-enhanced MEK/ERK activation. Reactive Oxygen Species mitogen-activated protein kinase 1 Homo sapiens
2 In contrast, an ROS inhibitor prevented the anti-Siglec-8/IL-5-induced enhancement of ERK phosphorylation and cell death. Reactive Oxygen Species mitogen-activated protein kinase 1 Homo sapiens
3 Collectively, these data suggest that the enhancement of ERK phosphorylation is downstream of ROS generation. Reactive Oxygen Species mitogen-activated protein kinase 1 Homo sapiens
4 CONCLUSIONS: In activated eosinophils ligation of Siglec-8 leads to ROS-dependent enhancement of IL-5-induced ERK phosphorylation, which results in a novel mode of biochemically regulated eosinophil cell death. Reactive Oxygen Species mitogen-activated protein kinase 1 Homo sapiens
