Characterization of CD30

Reed-Sternberg cell

In 1982 Stein and colleagues identified a new monoclonal antibody, Ki-1, that was specific for Hodgkin and Reed-Sternberg cells of Hodgkin lymphoma (HL) and a small population of lymphoid cells.1,2 The antigen recognized by Ki-1, designated as CD30, was found to be expressed not only in HL, but also on large-cell neoplasms subsequently designated anaplastic large cell lymphoma (ALCL).3,4

CD30 is a transmembrane glycoprotein with a molecular weight of 120 kDa.5,6 It is a member of the tumor necrosis factor receptor (TNFR) superfamily, which is likely to be crucial for regulating proliferation and differentiation of lymphocytes.7 An 85-kDa proteolytic fragment defined as soluble CD30 (sCD30) can be detected in the sera of patients with CD30-positive lymphomas and is also found in some patients with bone cancer, rheumatoid arthritis, atopic dermatitis and other reactive disorders, particularly during the acute phase of the disease.8,9,10,11 It has been suggested that high serum levels of sCD30 represent an independent predictor of disease progression and poor prognosis for patients with CD30-positive lymphomas.8,12
