During infection with Mtb, M. bovis BCG (BCG), and M. abscessus, macrophages from Mfn2 CKO mice had a higher capacity to replicate, with higher levels of intracellular colony forming units (CFUs) at different multiplicities of infection (MOIs), as compared to BMDMs from Mfn2 WT mice (Fig. 1a–c). This evidence concerns the gene MFN2 and infection.
