Critical Role of mitochondria in AKI. (A) In unstressed, healthy mitochondria, the integrity of both MOM and MIM is maintained to retain cytochrome c (Cyt C) in cristae and mtDNA in matrix. MICOS, including mitofilin, preserves the cristae structure and regulates the activity of ATP synthase. The newly identified MA-5 binds to mitofilin to facilitate ATP generation via ATP synthase (Suzuki et al.). (B) Upon stress, mitochondria become permeable at both MOM and MIM, leading to the release of cytochrome c, MPT, loss of membrane potential, inactivation of ATP synthase, and production of ROS for cell injury and death. Dying or dead cells release mtDNA to activate systemic inflammation via TLR9 to further induce AKI (Tsuji et al.). H+, proton; Pi, phosphate; PTP, permeability transition pore.
