Tissueliver, pancreas
Tissue SpecificityPlasma. Synthesized in the liver. Like the related alpha-1-antitrypsin, its concentration increases in the acute phase of inflammation or infection. Found in the amyloid plaques from the hippocampus of Alzheimer disease brains. {ECO:0000269|PubMed:3257719, ECO:0000269|PubMed:9880565}.
