title: [Mechanism of intracellular parasitism by Mycobacterium tuberculosis].
abstract: Mycobacterium tuberculosis is an intracellular bacterium that can replicate within infected macrophages. The intracellular parasitism by M. tuberculosis results from arresting phagosome maturation and inhibiting phagolysosome biogenesis in infected macrophages. It has been thought that M. tuberculosis arrests the maturation of its phagosome at the early stage. Several reports attended to the localization of Rab GTPases on mycobacterial phagosomes. Rab GTPases regulate membrane trafficking, but details of how Rab GTPases regulate phagosome maturation and how M. tuberculosis modulates their activities during inhibiting phagolysosome biogenesis remains elusive. Here, we introduce the new findings that M. tuberculosis alters the localization of Rab GTPases regulating phagosome maturation during inhibiting phagolysosome biogenesis.
