CD 57
Also known as Cd 57 Immunohistochemistry BloodWhat is this test?
CD57 is a 110-kD glycoprotein that is selectively expressed on natural killer cells and a subset of follicular T helper cells. Antibodies to CD57 also stain the myelin sheaths of central and peripheral nervous system cells. In normal tonsil, CD57 will stain a minor population of lymphocytes in the germinal centers. It is immunoreactive in tumors of neuroectodermal origins such as small cell carcinoma of the lung and carcinoid tumors, and is positive in adenocarcinomas of the prostate as well as normal and hyperplastic prostatic epithelium. Increased numbers of CD57-positive T cells are present in the background of lymphocyte-predominant Hodgkin lymphoma.
Also known as IHC Marker CD 57 Immunohistochemistry Blood, CD 57 Count Immunohistochemistry Blood, CD 57 Count, IHC Marker CD 57.
