Researchers from the Institut Pasteur, CNRS and Inserm, in collaboration with a team from Switzerland, have discovered a previously unknown mechanism by which L. pneumophila targets mitochondria to modulate mitochondrial dynamics and thereby impairs mitochondrial respiration which in turn leads to a change in the cellular metabolism.

The researchers have identified the following mechanism: L. pneumophila establishes transient, highly dynamic contacts with host mitochondria and secretes an enzyme called MitF that modifies the shape of the mitochondria by inducing DNM1L (a host protein that is necessary for fragmenting mitochondria) depended mitochondrial fragmentation.
