HUMAN PHENOTYPE - ANNOTATIONS

The Human Phenotype Ontology (HPO) is downloaded weekly from http://compbio.charite.de/hudson/job/hpo/lastStableBuild/artifact/ontology/release/hp.obo. The file downloaded is considered the "last stable build" available for the ontology. For more about the HPO, view their website at http://www.human-phenotype-ontology.org/.

Definition:Cholangitis characterized by the accumulation of granulomas. Granulomas are aggregates of modified macrophages (epithelioid cells) and other inflammatory cells that accumulate after chronic exposure to antigens. The underlying trigger may be exposure to noxious agents that cannot be biochemically degraded or to immune dysfunction. The ultimate result is a release of a variety cytokines that stimulate mononuclear cells that fuse to form multinucleated giant cells with a surrounding rim of lymphocytes and fibroblasts.
Comment:Granulomatous cholangitis involving the interlobular bile ducts constitutes the hallmark of primary biliary cholangitis and is also found in drug-induced liver disease and sarcoidosis.
