What is Pulmonary Alveolar Proteinosis (PAP)?

PAP is a rare lung disorder characterized by the excessive accumulation of phospholipids and surfactant apoproteins in the lower respiratory tracts (alveoli and terminal bronchioli), which causes gradual but progressive respiratory failure. The number of patients are estimated to be 800-1,200 all over Japan.

The aim of this site is to promote the development of new therapies and to construct a support system for patients by providing medical staff with accurate information about PAP and encouraging communication.

This site was established by The Pulmonary Alveolar Proteinosis Research Group granted by【Practical Research Project for Rare / Intractable Diseases】 from Japan Agency for Medical Research and Development, AMED.
