CD30 is a cytokine receptor belonging to the TNF superfamily (TNFRSF8) that acts as a regulator of apoptosis. The presence of CD30 antigen is important in the diagnosis of Hodgkin disease and anaplastic large cell lymphoma. There have been sporadic reports of CD30 expression in nonlymphoid tumors, including malignant mesothelioma. Given the remarkable success of brentuximab vedotin, an antibody...

OBJECTIVE CD30 antigen has long been considered to be restricted to the tumour cells of Hodgkin's disease and of anaplastic large cell lymphoma as well as to T and B activated lymphocytes. It is now apparent that the range of normal and neoplastic cells, which may express CD30 antigen, is much wider than was at first thought. In order to gain insight into the physiological function of CD30 anti...

CD30 is a member of the tumor necrosis factor receptor superfamily. CD30 was originally described as a cell surface antigen on primary and cultured Hodgkin's and Reed-Sternberg cells. In this study, recombinant human CD30 ligand was expressed on the surface of CV-1/EBNA cells and tested for biologic activities on a variety of different CD30+ human lymphoma cell lines. CD30 ligand enhanced Ig se...

Originally, expression of the CD30 antigen was shown to be typical of the tumor cells of Hodgkin disease and of anaplastic large cell lymphomas. In reactive lymphoid tissue, CD30 is expressed only in a small population of activated lymphoid blasts. Since then, several reports have been published describing CD30 expression in non lymphoid tissues and neoplasms, such as embryonal carcinomas, semi...

S INCE THE INITIAL description of the Ki-l monoclonal antibody (MoAb) in 1982,' there has been an overwhelming flood of information concerning the Hodgkm's disease @)associated molecule CD30. In a diagnostic point of view, the Ki-l antibody enabled in 1985' the identification of a new category of non-Hodgkn's lymphomas designated as Ki"D30 anaplastic large cell lymphoma (ALCL).' The discovery t...

The peripheral blood of a 3 month old boy with disseminated tuberculosis showed CD30 positive monocytes on flow cytometric analysis. His liver contained CD30 positive staining macrophages and giant cells. CD30 is an activation antigen which has not been previously found on peripheral blood monocytes.

Observation: The CD30 antigen is a type-1 transmembrane glycoprotein which is a member of the tumor necrosis factor receptor family and may be expressed on activated B and T cells. CD30+ lymphoproliferative disorders (CD30+ LPDs) mainly include primary cutaneous CD30+ anaplastic large-cell lymphoma (pcALCL) and lymphomatoid papulosis (LyP). Other CD30 +LPD showing skin lesions are large cell tr...

Interest in CD30 has mainly focused on its ability to discriminate between T helper (Th)2 and Th1 subpopulations. The role of CD30 as the marker for Th2 cells is still controversial, which may be due to the fact that the expression and the role of CD30 is not fully understood. The data presented in this paper provides information on the expression and activity of CD30 in T cell lines specific t...

Animal models are essential for elucidating the molecular mechanisms of carcinogenesis. Hodgkin's and many diverse non-Hodgkin's lymphomas overexpress the Hodgkin's disease antigen CD30 (CD30(hi)), a tumor necrosis factor receptor II family member. Here we show that chicken Marek's disease (MD) lymphoma cells are also CD30(hi) and are a unique natural model for CD30(hi) lymphoma. Chicken CD30 r...
