About us

The profound success of pathogens such as Mycobacterium tuberculosis and HIV in causing disease depends on their ability to successfully utilize the host’s cellular machinery for their own advantage to avert its immune system. Understanding these pathways or processes essential for the life cycle of these pathogens is crucial, as it represents potential targets for new drug strategies.
