Abstract
Neutrophil mitochondria are in a state of dynamic equilibrium, which is supported by two opposite processes: fusion and fission. Numerous studies have shown that the morphology of mitochondria is closely related to their functional activity. However, it was found that proteins involved in the process of mitochondrial dynamics can modulate other functions of mitochondria too. As was shown in our work on the model of human neutrophils, the dynamin-related protein 1 (DRP1) responsible for mitochondrial fission, is involved in NETosis, realizing its classic function. At the same time, the suppression of the oxidative burst via the DRP1 was due to its non-classical function associated with its action on the mitochondrial pore.
