What drives this change at the cellular level
However, a growing body of evidence suggests that mitochondria are critically involved in necroptosis initiation and execution, including mitROS-mediated RIPK1 and RIPK3 recruitment, feedback RIPK1/RIPK3-mediated mitROS generation, RIPK3-dependent pyruvate dehydrogenase complex-mediated ROS production, or phosphoglycerate mutase family member 5 (PGAM5)-dependent dynamin-related protein 1 (Drp1)-mediated necroptosis (PGAM5 is activated downstream of the RIPK1/RIPK3/MLKL complex) [137,138,139,140]
