  • Title
    Evaluating the immunometabolic potential of desferrioxamine to augment antibiotic treatment against Mycobacterium tuberculosis
    Summary
    Tuberculosis (TB) remains a global scourge causing more than one million deaths annually. TB therapy is characterised by a long duration of treatment and the administration of a number of antibiotic drugs to overcome drug resistance. The increasing prevalence of drug-resistant TB demonstrates that current treatments are inadequate and there is an urgent need for novel therapies. Research is now focused on the development of host-directed therapies (HDTs) which can be used in combination with existing antimicrobials, with a special focus on promoting host defense, particularly cellular metabolism. Immunometabolic reprogramming is integral to TB host defense and fundamental to eradicating TB infection. Moreover, TB pathophysiology is interconnected with iron metabolism. Iron is crucial for the survival of Mycobacterium tuberculosis (Mtb), the bacteria that causes TB disease. Iron chelation has therefore been suggested as a HDT. In addition to its direct effects on iron availability, it is hypothesised that iron chelators can also enhance immunometabolism through the stabilisation of HIF1α. We propose to evaluate the immunometabolic potential of anti-TB agents in combination with the iron chelator, desferrioxamine (DFX), to examine if such anti-TB/DFX combinatorial agents can augment antibiotic efficacy in human alveolar macrophages infected with clinical isolates of drug-resistant Mtb.
