Basic, clinical and translational research over the past two decades have raised PAP from obscurity, identifying the molecular pathogenesis in over 90% of cases as a spectrum of diseases involving the disruption of GM-CSF signaling. Autoimmune PAP represents the vast majority of cases and is caused by neutralizing GM-CSF autoantibodies. Genetic mutations that disrupt GM-CSF receptor signaling comprise a rare form of hereditary PAP. In both autoimmune and hereditary PAP, loss of GM-CSF signaling blocks the terminal differentiation of alveolar macrophages in the lungs impairing the ability of alveolar macrophages to catabolize surfactant and to perform many host defense functions. Secondary PAP occurs in a variety of clinical diseases that presumedly cause the syndrome by reducing the numbers or functions of alveolar macrophages, thereby impairing alveolar macrophage-mediated pulmonary surfactant clearance. A similar phenotype occurs in mice deficient in the production of GM-CSF or GM-CSF receptors. PAP and related research has uncovered a critical and emerging role for GM-CSF in the regulation of pulmonary surfactant homeostasis, lung host defense, and systemic immunity.","is_dataset_classified":null,"base_score":5.41610040220442,"endowment":5.41610040220442,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"20338813","pmcid":"PMC2866141","openalex_id":"https://openalex.org/W2015640498","authors":[],"funders":[{"funder_name":"NHLBI NIH HHS","grant_id":"HL0085453","title":null},{"funder_name":"NHLBI NIH HHS","grant_id":"R01 HL085453","title":null},{"funder_name":"NHLBI NIH HHS","grant_id":"R21 HL106134","title":null},{"funder_name":"NCRR NIH HHS","grant_id":"U54 RR019498","title":null}],"total_grants":4,"fwci":9.7143,"citation_percentile":0.98577183,"influential_citations":0,"citation_trend":[{"year":2012,"count":13},{"year":2013,"count":17},{"year":2014,"count":26},{"year":2015,"count":19},{"year":2016,"count":18},{"year":2017,"count":20},{"year":2018,"count":9},{"year":2019,"count":13},{"year":2020,"count":14},{"year":2021,"count":14},{"year":2022,"count":10},{"year":2023,"count":15},{"year":2024,"count":13},{"year":2025,"count":3},{"year":2026,"count":4}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S1521661610000768?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S1521661610000768?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.clim.2010.02.017","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/20338813","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/2866141","host_type":"repository"}],"fields_of_study":["Neonatal Respiratory Health Research","Congenital Diaphragmatic Hernia Studies","Respiratory viral infections research","Animals","Autoantibodies","Autoantigens","Autoimmune Diseases","Granulocyte-Macrophage Colony-Stimulating Factor","Humans","Mice","Pulmonary Alveolar Proteinosis","Pulmonary Surfactants","Receptors, Granulocyte-Macrophage Colony-Stimulating Factor"],"mesh_terms":["Animals","Autoantibodies","Autoantigens","Autoimmune Diseases","Humans","Pulmonary Alveolar Proteinosis","Pulmonary Surfactants","Granulocyte-Macrophage Colony-Stimulating Factor","Receptors, Granulocyte-Macrophage Colony-Stimulating Factor","Mice"],"keywords":["Pulmonary alveolar proteinosis","Alveolar macrophage","Immunology","Lung","Pathogenesis","Macrophage","Receptor","Autoantibody","Medicine","Immune system","Pathology","Biology","Antibody","Genetics","Internal medicine"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[{"name":"refsnp"}],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-06T09:42:16.730708Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
