Visualizing mitochondrial electron transport chain complexes and super-complexes during infection of human macrophages with Legionella pneumophila.

The ultrastructure of mitochondria is pivotal for their respiratory activity. Thus, the regulation of the assembly of the super-complexes (SCs) of the mitochondrial electron transport chain (ETC) might be a core aspect of macrophage immunometabolism during bacterial infection. In order to study the impact of infection by Legionella pneumophila on the configuration of mitochondrial complexes and SCs in human macrophages, we have adapted and combined different methods such as cell sorting of infected cells, magnetic isolation of highly pure and functional mitochondria, quality control of mitochondrial purity by flow cytometry, and BN-PAGE (Blue-Native Polyacrylamide Gel Electrophoresis) coupled to Western Blot using near-infrared (NIR) fluorescence.
