Systems biology of tuberculosis

Area of Science:

• Systems biology
• Mycobacterium tuberculosis research
• Host-pathogen interactions

Background:

• Systems biology integrates diverse data to understand biological systems and their responses.
• Genome-scale data for Mycobacterium tuberculosis facilitates systems-level investigations.
• Indian research efforts focus on Mycobacterium tuberculosis and host interactions.

Purpose of the Study:

• To review Indian systems-level studies on Mycobacterium tuberculosis and host interactions.
• To highlight insights gained into pathogen survival, host factors, and pathogenesis.
• To discuss drug target identification strategies and drug resistance.

Main Methods:

• Modeling and simulation of metabolic pathways and protein-protein interaction networks.
• Experimental studies of host-pathogen interactions using siRNA techniques.
• Development of a drug target identification pipeline integrating interactome, reactome, genome, pocketome, and transcriptome data.

Main Results:

• Identification of essential proteins for bacterial survival and influential network proteins.
• Characterization of highly connected pathways and host factors in TB infection.
• Gained insights into autophagy, pathogenesis, and the emergence of drug resistance.

Conclusions:

• Systems biology approaches provide a global perspective on Mycobacterium tuberculosis and host interactions.
• Integrated analyses are crucial for identifying novel drug targets and understanding drug resistance.
• Exploring host factors presents a promising avenue for TB therapeutic strategies.
