Mycobacterium tuberculosis and the host macrophage: maintaining homeostasis or battling for survival?
نویسندگان
چکیده
Mycobacterium tuberculosis is endowed with the ability to persist within its intracellular niche for years, often tilting the balance of the host–pathogen interaction in its favour. The host resists infection by releasing damaging free radicals, pushing the pathogen towards lysosomal degradation, releasing an arsenal of cytokines for triggering adaptive immunity and facilitating apoptosis for effective T cell antigen presentation. The bacterium counters these mechanisms and also metabolically reprograms the macrophage to its own benefit. Recent advances in these areas are reviewed here.

Pathogens infecting mammalian cells have developed various strategies to suppress and evade their hosts’ defensive mechanisms. In this line, the intracellular bacteria that are able to survive and propagate within their host cells must have developed strategies to avert their host’s killing attitude. Studying the interface of host-pathogen confrontation can provide valuable information for defi...
متن کاملIdentification of Mycobacterium tuberculosis adherence-mediating components: a review of key methods to confirm adhesin function
Anti-adhesion therapy represents a potentially promising avenue for the treatment and prevention of tuberculosis in a post-antibiotic era. Adhesins are surface-exposed microbial structures or molecules that enable pathogenic organisms to adhere to host surfaces, a fundamental step towards host infection. Although several Mycobacterium tuberculosis adhesins have been identified, it is predicted ...

Isoniazid, is the only antituberculous drug for which the relation between lack of virulence and acquisition of resistance was associated. INH-resistant mutants were shown to contain defective katG gene. Classical studies showed that INH-resistant south Indian isolates have lower virulence in guinea pigs and higher susceptibility to H2O2. It is of interest to assess the virulence in south India...
متن کاملCsoR Is Essential for Maintaining Copper Homeostasis in Mycobacterium tuberculosis
Mycobacterium tuberculosis, a pathogen infecting one third of the world population, faces numerous challenges within the host, including high levels of copper. We have previously shown that M. tuberculosis CsoR is a copper inducible transcriptional regulator. Here we examined the hypothesis that csoR is necessary for maintaining copper homeostasis and surviving under various stress conditions. ...
