In our final episode, we explore Dorothy Andersen’s legacy — what she left behind and how her work has lived on since her death. Describing her mentor’s influence on her life and career, Dr. Celia Ores gives us a rare look at what Dr. Andersen was really like. We then turn to researchers, physicians, and patients, who fill us in on the many areas of progress that have grown out of Dr. Andersen’s work. These major developments include the discovery of the cystic fibrosis gene, the tremendous impact of the drug Trikafta, and the lifesaving potential of gene editing techniques. We end the episode with an update on the effect Trikafta has had on the lives of many CF patients, who can now expect to live a normal life.
