How an unsolved medical mystery became a life-saving breakthrough
Dr. Mike Welsh's research into cystic fibrosis led to a breakthrough in understanding the disease, resulting in life-saving medications. The medications have transformed cystic fibrosis from a lethal diagnosis into a manageable condition for many patients.
Dr. Mike Welsh, a med student in the 1970s, encountered a young girl with severe cystic fibrosis. The girl's condition sparked Welsh's 50-year study of chloride movement across cells, crucial to understanding the disease. Welsh's research led to the development of medications that have revolutionized the treatment of cystic fibrosis. Patients like William O'Neal II and Grace Lidgett have reported significant improvements in their condition after taking the medications. O'Neal, who was given three months to live without a lung transplant, was able to walk and talk without struggling after starting treatment. Welsh and his colleagues were awarded the 2025 Lasker Award for their work, considered one of the most prestigious honors in biomedicine.
