HSC71 acetylation confers protection against Spiroplasma eriocheiris infection by inhibiting apoptosis and promoting ROS production in arthropods
This study reveals that Crat-mediated acetylation of HSC71 at lysine 579 enhances arthropod immunity against *Spiroplasma eriocheiris* by stabilizing HSC71 to suppress apoptosis and weakening its interaction with SOD to promote microbicidal ROS accumulation, a mechanism that can be therapeutically targeted via SIRT1 inhibition.
