Virtuous circulation of M2 macrophage polarization. IL-10 is the main anti-inflammatory factor secreted by M2 macrophages. It can up-regulate HO-1, an important molecule in the process of macrophages polarizing to M2, to promote macrophages to polarize M2 macrophages. It forms a virtuous cycle to inhibit liver ischemia-reperfusion injury.
