Thousands of Americans suffer from aPAP, a rare autoimmune lung disease caused by the progressive build-up of an oily substance normally present in the lungs called surfactant. In healthy people, surfactant forms a thin layer that lines the tiny air sacs (alveoli) of the lungs and helps them function while we breath. In people with aPAP, the surfactant over-accumulates, making the layer thicker in some air sacs and filling others, blocking oxygen from moving out of the air sacs and into the bloodstream.Read More
