However, Nrf2 activators augmented the RBC phagocytosis by cultured microglia [130,132], and Nrf2 is a key regulator of CD36, a scavenger protein, which plays a role in microglial phagocytosis of RBC [132], implicating a critical role of Nrf2 in hematoma clearance. The gene discussed is NFE2L2; the disease is hematoma.
