Fig. 8. Disturbance of suprachiasmatic nucleus function preserves cardiac function by IGF2-mediated macrophage transition.

Schematic cartoon illustrating the protective mechanism of SCN ablation against MI in mice: the increased expression of IGF2 in SCNx mice promotes localized resting macrophage transition into anti-inflammatory macrophages in the heart and eventually preserves cardiac function by promoting angiogenesis and inhibiting fibrosis in the infarcted heart.
