The study is the first to show that the female hormone estrogen promotes the presence of a particular form of bacteria which results in more severe symptoms for female cystic fibrosis patients. In addition, females who were taking the oral contraceptive pill, which decreases the amount of naturally occurring estrogen in their bodies, were found to have lower levels of the problematic bacteria.

The scientists report that destruction of lung tissue in mice induces smooth muscle cells surrounding the airways to secrete a protein known as fibroblast growth factor 10, which induces surviving epithelial cells in the airways to revert to a stem-cell state, proliferate, repair and repopulate the lining of the lungs.
