Intracellular transcriptional adaptation of Mycobacterium tuberculosis complex (MTC) clinical isolates inside activated murine macrophages


ABSTRACT: This study uses microarray analyses to examine transcriptional responses of Mycobacterium tuberculosis complex clinical isolates to phagosomal cues encountered inside activated (IFN-gamma+LPS) murine bone marrow-derived macrophages 24hr post-infection. Transcript levels of intracellular mycobacteria were compared to extracellular bacteria of the same strain (An aliquot of the inoculum used to infect macrophages was incubated in the absence of macrophages for 24hr in an identical flask).

Tuberculosis exerts a tremendous burden on global health, with approximately 9 million new infections and approximately 2 million deaths annually. The Mycobacterium tuberculosis complex (MTC) was initially regarded as a highly homogeneous population; however, recent data suggest the causative agents of tuberculosis are more genetically and functionally diverse than appreciated previously. The impact of this natural variation on the virulence and clinical manifestations of the pathogen remains la  ...[more]
