Towards new drugs and diagnostics for tuberculosis: Elucidating and exploiting essential pathways in the Mycobacterium tuberculosis pathogen

School of Life Sciences

About the Project

This project is available through the MIBTP programme on a competition basis. The successful applicant will join the MIBTP cohort and will take part in all of the training offered by the programme. For further details please visit the MIBTP website - https://warwick.ac.uk/fac/cross_fac/mibtp/

Tuberculosis (TB) is a major global health challenge. TB is now the leading cause of death from a single infectious agent worldwide killing more people than HIV and malaria combined. As the number of drug-resistant TB infections escalates and the current front-line drugs become ineffective we urgently need to develop new strategies to control the TB epidemic. In order to develop new interventions we need to understand the fundamental biology and biochemistry of Mycobacterium tuberculosis – the causative agent of TB.

Mycobacterium tuberculosis (Mtb) is a very unusual pathogen and has evolved an incredible ability to survive in the human host for decades, capable of reactivating to trigger TB infection. However, our knowledge of the nutrients/energy sources that M. tuberculosis uses and the mechanisms that are involved in their uptake and subsequent metabolism is poorly understood.

Research in our laboratory is focused on understanding the molecular mechanisms that Mtb uses to obtain and process these essential nutrients. We are then using this fundamental information to develop routes and strategies to target these processes to develop new anti-tubercular therapeutics/diagnostics.

The main themes in our lab are: 1) determining the molecular mechanisms of enzymes involved in key transport and metabolic pathways in Mtb 2) development of new chemical tools and probes to understand the Mtb pathogen, 3) discovering new approaches that can either kill and/or detect Mtb

We use a multidisciplinary approach that includes biochemistry, biophysics, structural biology, microbiology and molecular genetics, synthetic chemistry and chemoenzymatic methods, analytical chemistry and molecular modelling. Overall this multidisciplinary approach uses the latest techniques to probe important, fundamental mechanisms of this major global pathogen. Some examples of our recent exciting findings are listed in the references below. Unravelling these essential processes will lead to valuable new insights into what Mtb ‘eats’ and how it uses these energy sources that can be exploited to develop new molecules with novel modes of action that either kill Mtb or can be used for detection/diagnosis.
