CD30L, a type II membrane protein, is a member of the TNF ligand family. The extracellular domain of CD30L contains two cysteine residues that is unique within the family and may form inter-subunit disulfide linkage. Even though CD30L contains the TNF-like extracellular domain, it is less clear if the protein is normally a dimer, trimer or a higher order oligomer. In addition, the biological function of the CD30L-CD30 axis in healthy individuals remains poorly understood as no human disease have been linked to defects along this axis.
As the CD30L expression is highly restricted to a small number of normal cells, its abundant expression in malignant cells seems to make it a good target for antibody therapy. Recently, CD30L was shown to be critical for the antigen-triggered proliferation and class switching of B lymphocytes. The observations that CD30L has diverse biological activity in different CD30-expressing cancers, ranging from enhancing survival to cell cycle arrest, make the CD30L-CD30 axis a less clear therapeutic target.
Nonetheless, a chimeric anti-CD30 antibody was reported to induce cell cycle arrest in Hodgkin-derived cell lines and is in a phase I study in patients with relapsed Hodgkin disease or CD30+ hematologic malignancies.
