IgG class ANCA directed to proteinase 3 (PR3) of neutrophils and monocytes seem to be directly involved in the pathophysiology of vascular damage by causing excessive neutrophil activation and vessel wall destruction. PR3 and elastase are important players in the mechanisms of vascular necrosis. Methods of detecting ANCA have now been defined but are not uniformly used, even though clinical decisions heavily depend on correct ANCA results.", "distribution": [{"@type": "dcat:Distribution", "description": "Visit the original government dataset for complete information, documentation, and data access.", "downloadURL": "https://www.ncbi.nlm.nih.gov/pmc/articles/PMC130013/", "mediaType": "text/html", "title": "Official Government Data Source"}], "identifier": "https://healthdata.gov/api/views/giri-eyzk", "issued": "2025-07-14", "keyword": ["anca-vasculitis", "autoimmune-disease", "nih", "proteinase-3", "small-vessel-vasculitis"], "landingPage": "https://healthdata.gov/d/giri-eyzk", "modified": "2025-09-06", "programCode": ["009:033"], "publisher": {"@type": "org:Organization", "name": "National Institutes of Health"}, "theme": ["NIH"], "title": "What you should know about PR3-ANCA: An introduction"}
