Human CD30 Protein, ECD (Extracellular Domain), Recombinant

Description

CD30/TNFRSF8 is a single-pass type I transmembrane glycoprotein of the TNF receptor superfamily (TNFRSF). The ligand for CD30 is CD30L/CD153, a member of the TNF superfamily (TNFSF8). CD30L-CD30 ligation mediates pleiotropic effects, including cell proliferation, activation, differentiation and apoptosis. CD30 is expressed in activated, but not resting, T and B cells. CD30 can regulate proliferation of lymphocytes and may also play an important role in human immunodeficiency virus (HIV) replication. As a regulator of apoptosis, CD30 protein induces cell death or proliferation, depending on the cell type, and has been shown to limit the proliferative potential of autoreactive CD8 effector T cells and protect the body against autoimmunity. CD30 contributes to thymic negative selection by inducing the apoptotic cell death of CD4+CD8+ T cells. In B cells, CD30 ligation promotes cellular proliferation and antibody production. CD30 is overexpressed in various hematological malignancies, including Reed-Sternberg cells in Hodgkin's disease (HD), anaplastic large cell lymphoma (ALCL) and subsets of Non-Hodgkin's lymphomas (NHLs). CD30 is also found in leukocytes in patients with chronic inflammatory diseases, including lupus erythematosus, asthma, rheumatoid arthritis and atopic dermatitis.
