Scientific Data Images for CD57 Antibody (PD00-21)
Immunohistochemistry: CD57 Antibody (PD00-21) [NBP3-32160]
Immunohistochemistry: CD57 Antibody (PD00-21) [NBP3-32160] - Immunohistochemical analysis of paraffin-embedded human Hodgkin's lymphoma tissue with Mouse anti-CD57 antibody (NBP3-32160) at 1/50 dilution.The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 9.0) for 20 minutes. The tissues were blocked in 1% BSA for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (NBP3-32160) at 1/50 dilution for 1 hour at room temperature. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.

Background: CD57
CD57 expression has become a common pathological marker. CD57+ CD8+ T cell expression is observed in various cancers and is often linked to reduced survival (3). On the other hand, CD57+ NK cell expression is associated with less severe disease and better prognosis in cancer patients (3). CD57 is also associated with immune dysfunction and autoimmune disease (3,4). For example, T cell immunosenescence is characterized by an upregulation of CD57 along with KLRG-1 and a loss of CD27 and CD28 expression (4). Expanded autoreactive T cells are also related to diseases including multiple sclerosis (MS) and rheumatoid arthritis (RA) (3). Conversely, reduced numbers of CD57+ NK cells and NK cell cytotoxicity is observed in various autoimmune diseases such as apoptotic dermatitis and sjogren's syndrome (3).
