After a severe bout with a respiratory illness like flu, COVID, or RSV some patients’ lungs never fully recover. In these cases, scientists have seen cells normally found in the upper airway growing deep in the lungs, where gas-exchange cells should be. While this regrowth may serve as a patch for the damage, the out-of-place cells, known as basal cells, don’t promote the same respiratory functions, and a reduction in lung capacity may result.
