A mycobacterial effector promotes ferroptosis-dependent pathogenicity and dissemination

Abstract

Ferroptosis is an iron-dependent form of cell death whose role in infectious diseases is being elucidated. Here, Qiang et al. show that PtpA, an effector secreted by Mycobacterium tuberculosis, induces ferroptosis by hijacking host arginine methyltransferase PRMT6 to promote its pathogenicity and dissemination.
