Ferroptosis Is a Potential Therapeutic Target for Pulmonary Infectious Diseases

ABSTRACT

Ferroptosis is a new type of iron-dependent cell death caused by lipid peroxide (LPO) accumulation and involved in disease of pulmonary infection. The dysregulation of iron metabolism, the accumulation of LPO, and the inactivation and consumption of glutathione peroxidase 4 (GPX4) are the crucial cause of ferroptosis. Pulmonary infectious diseases caused by Pseudomonas aeruginosa (PA), Mycobacterium tuberculosis (MTB), and severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2) are associated with ferroptosis. Ferroptosis may be a potential therapeutic target for pulmonary infectious diseases. However, the mechanisms by which these infections are involved in ferroptosis and whether pulmonary infectious diseases caused by Staphylococcus aureus, Klebsiella pneumoniae, and Leishmania spp are related to ferroptosis are unclear. Accordingly, more researches are needed.Copyright © 2023 Yurong Zhang et al.
