Learning Theatre Title: Autoimmune Pulmonary Alveolar Proteinosis (aPAP): Understanding the Disease and Patient Experience Date/Time: Tuesday, October 20, 2026, 12:30 — 1:15 PM MST Location: Phoenix Convention Center, Learning Theatre 4 Speakers: Bruce C. ; Eric and Karli, patients living with aPAP About Autoimmune Pulmonary Alveolar Proteinosis (aPAP) Autoimmune PAP is a rare lung disease characterized by the abnormal build-up of surfactant in the alveoli. Surfactant consists of proteins and lipids and is an important physiological substance that lines the alveoli to prevent them from collapsing.

In a healthy lung, excess surfactant is cleared and digested by immune cells called alveolar macrophages. Alveolar macrophages need to be stimulated by granulocyte-macrophage colony-stimulating factor (GM-CSF) to function properly in clearing surfactant, but in aPAP, GM-CSF is neutralized by antibodies against GM-CSF, rendering macrophages unable to adequately clear surfactant. As a result, an excess of surfactant accumulates in the alveoli, causing impaired gas transfer, resulting in clinical symptoms of shortness of breath, often with cough and frequent fatigue.

Patients may also experience episodes of fever, chest pain, or coughing up blood, especially if secondary lung infection develops. In the long term, the disease can lead to serious complications, including lung fibrosis and the need for a lung transplant.
