*SUBJECT TO FUNDING*
Non-tuberculous mycobacterial (NTM) infections are increasingly commonly identified in patients with chronic lung disease. These bacteria usually do not cause disease in the healthy lung, but can complicate and perpetuate pre-existing lung disease, such as chronic obstructive lung disease (COPD), CF and bronchiectasis. Current management of NTM lung disease involves multiple antibiotics for prolonged periods (of 12-18 months); such courses are difficult to tolerate, particularly in the elderly, and frequently do not eradicate the infection. There is an urgent need to identify new strategies to targets these bacteria, and reduce the tissue damage they drive. Mesenchymal stromal cells (MSCs) have anti-inflammatory and anti-microbial activities. This project will investigate their capacity to kill non-tuberculous mycobacteria, within and outside of macrophages (the cells which take up and contain mycobacteria in patients). In addition, we will investigate their capacity to reduce the production of enzymes (from infected macrophages) that drive tissue destruction in the lung, and the production of inflammatory cytokines. The mechanisms regulating these effects will be defined. Finally we will investigate whether we can prime or pre-condition MSCs to increase their anti-microbial and anti-inflammatory effects on non-tuberculous mycobacteria. Taken together, these experiments will define whether MSCs have therapeutic potential in the management of NTM lung disease, and identify how they mediate this effect. Mechanistic studies to understand their mode of action may allow us to identify novel further methods of treating NTM.
