Targeting iRhom2/ADAM17 attenuates COVID-19-induced cytokine release from cultured lung epithelial cells.

The COVID-19 pandemic, caused by SARS-CoV-2, continues to pose a significant global health challenge, with acute respiratory distress syndrome (ARDS) being a major cause of mortality. Excessive cytokine release (cytokine storm) has been causally related to COVID-19-associated ARDS. While TNF-α inhibitors have shown potential in reducing inflammation, their broad effects on TNF-α signaling, including both pro- and anti-inflammatory pathways, present significant challenges and side effects in clinical use.
