Abstract
In alternative embodiments, provided are compositions, including products of manufacture and kits, and methods, for inhibiting the ability of neutrophils, or polymorphonuclear leukocytes (PMNs), to release reactive oxygen species (ROS), thus also inhibiting or ameliorating neutrophil (PMN) contribution to an inflammatory response, thus also treating, ameliorating or preventing neutrophil (PMN)-meditated inflammatory-related pathologies such as acute respiratory distress syndrome (ARDS), including ARDS caused by a viral infection such as COVID-19.
