ATP6V1D and Cirrhosis: From the early phagosome to the mature phagosome, expression levels of ATP6V0A1 (ATPase H+ transporting V0 subunit A1), ATP6V0C (ATPase H+ transporting V0 subunit C), and ATP6V1D (ATPase H+ transporting V1 subunit D), which encode ATPase, increased in PBMCs from patients with decompensated cirrhosis.
