Primary cutaneous CD30(+) lymphoproliferative disorders (CD30(+) LPDs) are the second most common form of cutaneous T-cell lymphomas and include lymphomatoid papulosis and primary cutaneous anaplastic large-cell lymphoma. Despite the anaplastic cytomorphology of tumor cells that suggest an aggressive course, CD30(+) LPDs are characterized by an excellent prognosis. Although a broad spectrum of ...
BACKGROUND CD30(+) T-cell lymphoproliferations comprise a spectrum of clinically heterogeneous entities, including systemic anaplastic large cell lymphomas (ALK(-) and ALK(+)) and primary cutaneous CD30(+) T-cell lymphoproliferative disorders. While all these entities are characterized by proliferation of highly atypical, anaplastic CD30(+) T cells, the expression of T-cell specific antigens in...
OBJECTIVES The immunologic status of kidney allograft recipients affects transplant outcome. High levels of pretransplant serum soluble CD30 correlate with an increased risk of acute rejection. Studies show conflicting results. We evaluated the relation between pretransplant serum sCD30 levels with the risk of posttransplant acute kidney rejection in renal transplant recipients. MATERIALS AND...
CD30 is a member of the tumor necrosis factor receptor superfamily. It is characteristically expressed in certain hematopoietic malignancies, including anaplastic large cell lymphoma and Hodgkin lymphoma, among others. The variable expression of CD30 on both normal and malignant lymphoid cells has focused research efforts on understanding the pathogenesis of CD30 upregulation, its contribution ...
BACKGROUND AND OBJECTIVE In this study we describe a newly established CD30+ Epstein Barr virus (EBV)-infected B cell line derived from an EBV-infected B cell culture (utilized, once irradiated, as a feeder) which showed a B clonal rearrangement and strong CD30 antigen expression. DESIGN AND METHODS The cells injected into SCID mice were able to grow giving rise to CD30+ solid tumors with the...
A number of different immunotoxins composed of cell-specific targeting structures coupled to plant or bacterial toxins have increasingly been evaluated for immunotherapy. Because these foreign proteins are highly immunogenic in humans, we have developed a new CD30 ligand-based fusion toxin (Ang-CD30L) using the human RNase angiogenin. The completely human fusion gene was inserted into a pET-bas...
Lymphoid tissue inducer cells express a diverse array of tumor necrosis family ligands, including those that bind CD30 and the lymphotoxin beta receptor. Both of these signaling pathways have been linked with B/T segregation in the spleen. In this study, we have dissected a lymphotoxin-independent CD30-dependent signal for the induction of expression of the T zone chemokine, CCL21. Reduced expr...
Although several imaging modalities are widely used for tumor imaging, none are tumor type-specific. Different types of cancer exhibit differential therapeutic responses, thus necessitating development of an imaging modality able to detect various tumor types with high specificity. To illustrate this point, CD30-specific oligonucleotide aptamer in vivo imaging probes were conjugated to the near...
The human lymphocyte activation marker CD30 is highly overexpressed on Hodgkin/Reed-Sternberg cells and represents an ideal target for selective immunotherapy. We used the murine anti-CD30 hybridoma Ki-4 to construct a new recombinant immunotoxin (rIT) for possible clinical use in patients with CD30(+) lymphoma. Hybridoma V genes were polymerase chain reaction-amplified, assembled, cloned, and ...
BACKGROUND The serum level of soluble CD30 (sCD30) is known to be increased with several lymphomas and to correlate with prognosis. Primary effusion lymphoma (PEL) is a highly aggressive malignant lymphoma with poor prognosis, but the existence and significance of sCD30 in PEL have not yet been investigated in detail. OBJECTIVES Since the membrane type of CD30 is frequently expressed on the s...
