A breath of fresh ‘AIR’ in the study of lung repair and regeneration
NHLI researchers Róisín Mongey and Dr Sally Kim provide an insight into developing a new tool – the AIR model – for lung research and drug development.
Lung diseases represent a significant global health burden costing the NHS upwards of £1 billion annually. A hallmark of chronic and acute adult lung diseases such as Chronic Obstructive Pulmonary Disease (COPD), Idiopathic Pulmonary Fibrosis (IPF) and COVID-19, is lung damage. The lungs are usually capable of repairing damage but in some cases, this does not happen or the repair process goes awry for example going into overdrive and causing more damage. The result of this lack of repair or abnormal repair is persistent tissue damage and declining lung function.
There are almost no treatments available to repair the lung damage in these diseases. A bold, new approach to identify novel lung repair treatments for these diseases is needed. Unfortunately, there are several roadblocks to the development of curative treatments, the primary one being that we don’t fully understand how repair happens in the healthy lung under normal circumstances. The bottom line is that unless we can figure this out, it is unlikely that we will be able to develop successful new repair treatments. (more…)
