CX3CR1+ macrophages aggravate doxorubicin-induced cardiomyopathy by impairing cardiac mitophagy via the CSF1R-PARP1-IL1B axis.
Doxorubicin is a widely used chemotherapeutic agent, but its clinical application is hindered by severe cardiotoxicity. Among immune cells, Cx3cr1+ macrophages have emerged as key regulators of cardiovascular disease, with their development and maturation tightly controlled by CSF1R (colony stimulating factor 1 recepto...
