CD30, also known as TNFRSF8 (TNF receptor superfamily member 8), [5] is a cell membrane protein of the tumor necrosis factor receptor family and a tumor marker for anaplastic large cell lymphoma.
This receptor is expressed by activated, but not by resting, T and B cells. TRAF2 and TRAF5 can interact with this receptor, and mediate the signal transduction that leads to the activation of NF-kappaB. [6] It is a positive regulator of apoptosis, [7] and also has been shown to limit the proliferative potential of autoreactive CD8 effector T cells and protect the body against autoimmunity.[ citation needed ] Two alternatively spliced transcript variants of this gene encoding distinct isoforms have been reported. [5]
CD30 is associated with anaplastic large cell lymphoma. It is expressed in embryonal carcinoma but not in seminoma and is thus a useful marker in distinguishing between these germ cell tumors. [8] CD30 and CD15 are also expressed on Reed-Sternberg cells typical for Hodgkin's lymphoma. [9]
CD30 is the target of the FDA approved therapeutic brentuximab vedotin (Adcetris). It is approved for use in:
Brentuximab vedotin is also currently being studied in and recommended for treating:
CD30 has been shown to interact with TRAF5, [6] and TRAF2. [6] [7]
