Mycobacterium tuberculosis: success through dormancy.
Tuberculosis (TB) remains a major health threat, killing nearly 2 million individuals around this globe, annually. The only vaccine, developed almost a century ago, provides limited protection only during childhood. After decades without the introduction of new antibiotics, several candidates are currently undergoing clinical investigation. Curing TB requires prolonged combination of chemothera...
متن کاملDormancy models for Mycobacterium tuberculosis: A minireview
Dormancy models for Mycobacterium tuberculosis play important roles in understanding various aspects of tuberculosis pathogenesis and in the testing of novel therapeutic regimens. By simulating the latent tuberculosis infection, in which the bacteria exist in a non-replicative state, the models demonstrate reduced susceptibility to antimycobacterial agents. This minireview outlines the models a...
متن کاملCloning, Expression, and Refolding of PPE17 Protein of Mycobacterium Tuberculosis as a Promising Vaccine Candidate
Background: Tuberculosis as a global health problem requires special attention in the contexts of prevention and control. Subunit vaccines are promising strategies to protect burdens of tuberculosis via increasing the BCG protection. The present study aimed to design a vaccine study by means of high-throughput expression and correct refolding of recombinant protein PPE17. Methods: We aimed to c...
متن کاملThe evolution of Mycobacterium tuberculosis dormancy models
Mycobacterium tuberculosis is a remarkably successful human pathogen owing to its ability to enter into a persistent state. Towards obtaining a better understanding of the mycobacterial persistence mechanisms, several in vitro, ex vivo and animal models, that mimic one or more features of the host milieu, have been developed. Although none of the models is complete in itself, valuable insights ...
متن کاملThe DosS-DosT/DosR Mycobacterial Sensor System
DosS/DosR is a two-component regulatory system in which DosS, a heme-containing sensor also known as DevS, under certain conditions undergoes autophosphorylation and then transfers the phosphate to DosR, a DNA-binding protein that controls the entry of Mycobacterium tuberculosis and other mycobacteria into a latent, dormant state. DosT, a second sensor closely related to DosS, is present in M. ...
