SYNCRIP-Dependent Nox2 mRNA Destabilization Impairs ROS Formation in M2-Polarized Macrophages

M2 polarization of macrophages in sepsis results in an attenuated SYNCRIP binding to the 3'UTR of Nox2 mRNA, destabilizing Nox2 mRNA abundance and expression. Consequently, ROS formation needed to fight against recurrent infections is impaired. In conclusion, SYNCRIP-regulated Nox2 mRNA degradation mediates the hypoinflammatory phase of sepsis.
