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).
