The Mycobacterium tuberculosis (Mtb) persistence inside the human host relies on successful adaptation to host-induced stresses such as reactive oxygen species (ROS), reactive nitrogen species (RNS), iron starvation, low ...

The ability to perceive and adapt to environmental fluctuations, both internal and external, is a fundamental characteristic of life across diverse organisms. Within the context of pathogenic bacteria such as Mycobacterium ...

A distinctive feature of the bacterial RNA polymerase is the modular organization. The core of this enzyme, comprised of a dimer of the α subunit assembles with the β, β', and ω subunit. The core RNA polymerase enzyme ...

The genome in prokaryotes is restricted to a membrane-less compartment termed nucleoid. The genome is maintained in the compacted state within the nucleoid with the help of three key cellular factors viz, macromolecular ...

Mycobacterium tuberculosis, one of the leading causes of death worldwide even today, employs the second messenger cAMP extensively for its pathogenicity and persistence. Intracellular and extracellular levels of cAMP in ...

The work presented in this thesis endeavors to decode the details of the dynamics of MazE9 antitoxin of the Mycobacterium tuberculosis MazEF9 toxin-antitoxin system and the transcriptional autoregulation effected by it. ...

A typical two-component signaling system (TCSs) is composed of two transcriptionally coupled proteins (cognate pair) where one is a signal-sensing histidine kinase (HK) and the other, an output-generating response regulator ...

Mycobacterium tuberculosis (Mtb), a pathogenic bacterium, thrives and proliferates inside host macrophages, encountering a high level of reactive oxygen species and reactive nitrogen intermediates which is generated by the ...

Foamy macrophages or Foam cells are a critical cellular component of the granuloma formed during pulmonary infection. These lipid rich cells generally contain neutral lipids, Cholesteryl Esters (CE) and/or Triglycerides ...
