General description
Alpha-1-Antitrypsin is a protease inhibitor from the serpin superfamily, which inhibits a number of protease enzymes from inflammatory cells. It is an acute-phase plasma protein predominantly produced in hepatocytes, although it is also made in enterocytes and some mononuclear white blood cells. Alpha-1-antitrypsin immunohistochemistry is used to detect the accumulation of alpha-1-antitrypsin in hepatic lesions and histiocytic tumors.[1]
The immunohistochemical staining of Alpha-1-Antitrypsin is considered to be very useful in the study of inherited AAT deficiency, benign and malignant hepatic tumors, and yolk sac carcinomas. Positive staining for A-1-Antitrypsin may also be used in the detection of benign and malignant lesions of a histiocytic nature. The sensitivity and specificity of the results have made this antibody a useful tool in the screening of patients with cryptogenic cirrhosis or other forms of liver disease with portal fibrosis of uncertain etiology.

B Lindmark et al.
Histopathology, 16(3), 221-225 (1990-03-01)
We present a case of chronic liver disease with selective and exclusive hepatocyte endoplasmic reticulum storage of alpha 1-antichymotrypsin in the form of granules, detected by specific immunohistochemistry at the light microscopy level and corresponding to material found in dilated
H Takahashi et al.
Acta pathologica japonica, 40(9), 655-664 (1990-09-01)
Fifty-four adenoid cystic carcinomas (ACC) arising in major and minor salivary glands as well as in normal salivary glands were studied by immunohistochemistry for the presence of vimentin, neuron-specific enolase (NSE), alpha 1-antichymotrypsin (alpha 1-ACT) and alpha 1-antitrypsin (alpha 1-AT).
L G Kindblom et al.
Human pathology, 13(9), 834-840 (1982-09-01)
The aim of this study was to localize alpha 1-antitrypsin, ferritin, and lysozyme by means of the indirect immunoperoxidase technique and to evaluate the significance of these antigens as markers of histiocytic differentiation in tumors of a supposed dual fibroblastic-histiocytic
