Cholesterol Oxidase Is Indispensable in the Pathogenesis of Mycobacterium tuberculosis
Despite considerable research effort, the molecular mechanisms of Mycobacterium tuberculosis (Mtb) virulence remain unclear. Cholesterol oxidase (ChoD), an extracellular enzyme capable of converting cholesterol to its 3-keto-4-ene derivative, cholestenone, has been proposed to play a role in the virulence of Mtb. Here, we verified the hypothesis that ChoD is capable of modifying the bactericida...
متن کاملRole of cholesterol in Mycobacterium tuberculosis infection.
Mycobacterium tuberculosis (MTB) acquisition and utilization of nutrients within the host cell is poorly understood, although it has been hypothesized that host lipids probably play an important role in MTB survival. Cholesterol has recently been identified as an important lipid for mycobacterial infection. The mce4 transport system is required for cholesterol import into bacterial cells, and d...

متن کاملFoamy Macrophages in Mycobacterium tuberculosis Pathogenesis
The pathogen Mycobacterium tuberculosis (Mtb) is an infectious agent of tuberculosis. According to WHO report it is estimated that in 22 high burden of countries, there are 88% of TB cases and it is also estimated that 1/3 population of the planet is anchor with this bacterium [1]. Mtb modify immune system of host so that it can survive and maintain its growth in long term. Mtb can persist insi...
