Key result
ATF6 deficiency impairs CCR2 macrophage phenotype and function after myocardial ischemia-reperfusion injury.
Why the study?
The mechanisms by which ATF6 contributes to macrophage polarization and tissue repair after myocardial ischemia/reperfusion injury were unclear.
ATF6 contributes to cardiac macrophage polarization and metabolic reprogramming following myocardial ischemia/reperfusion injury, highlighting its role in post-injury inflammatory responses.
No immediate clinical implications in MI; leaves open ATF6 as target for modulating post-I/R macrophage responses in humans.

Wu et al. (2026) studied Myocardial ischemia/reperfusion (I/R) injury. ATF6 knockout vs. Wild-type (WT) was evaluated on Macrophage polarization and tissue repair. ATF6 deficiency was associated with altered phenotype and function of monocyte-derived CCR2 macrophages following myocardial ischemia/reperfusion injury.
