Suppression of CD8+ T cell activation is a critical mechanism used by Mycobacterium tuberculosis (MTB) to escape protective host immune responses. PPE38 belongs to the unique PPE family of MTB and in our previous study, PPE38 protein was speculated to participate in manipulating macrophage MHC class I pathway. To test this hypothesis, the function of(More)
Lipids have been identified as important carbon sources for Mycobacterium tuberculosis (Mtb) to utilize in vivo. Thus gluconeogenesis bears a key role for Mtb to survive and replicate in host. A rate-limiting enzyme of gluconeogenesis, fructose 1, 6-bisphosphatase (FBPase) is encoded by the gene glpX. The functions of glpX were studied in M. marinum, a(More)
The proline-proline-glutamic acid (PPE) family proteins are abundant only in pathogenic Mycobacteria, but their general functions are far from unveiled. To investigate their roles in how Mycobacterium tuberculosis (Mtb) resists killing by the host, 25 PPE recombinant Mycobacterium smegmatis strains that overexpress Mtb PPE proteins were constructed.
