The Ber-ACT35 mAb was raised against the human T-cell lymphotrophic virus (HTLV) 1-transformed, CD4+ HUT 102 cell line and recognizes the human homologue of the OX40 (hOX40) antigen. The analysis of the expression of hOX40 by immunohistochemical techniques in malignant lymphomas, carcinomas and non-malignant tissues of different organs shows that hOX40 expression was almost completely restricted to T lymphocytes. Besides T cells only a small subpopulation of macrophages in Langerhans' cell histiocytosis and a few blasts in B-cell non-Hodgkin's lymphoma (B-NHL) revealed a faint immunostaining with the Ber-ACT35 mAb. Furthermore, most of the hOX40+ T-cells are CD4+.

Members of the TNF receptor superfamily are type I membrane glycoproteins with limited homology (overall homologies: 25%-30%) in the extracellular domain containing variable numbers of cysteine-rich repeats. In contrast, the TNF ligand superfamily members (with the exception of LT-alpha) are type II membrane glycoproteins with limited homology to TNF (overall homologies: 20%) in the extracellular region. TNF and LT-alpha are trimeric proteins and are composed of beta-strands forming a beta-jellyroll, the homology of the beta-strand regions for the TNF ligand superfamily members suggests a similar trimeric or multimeric complex formation for the other members. A genetic linkage, as evidence for evolutionary relatedness, is also found by chromosomal cluster for CD30, CD120b, 4-1BB and OX40 to 1p36; CD27, CD120a and TNFR-RP to 12p13; TNF, LT-alpha and LT-beta to 6p21; CD27L and 4-1BBL to 19p13; CD95L and OX40L to 1q25. TNF, LT-alpha and LT-beta and their receptors (CD120a, CD120b, TNFR-RP) interact in a complex fashion. Other family members, however, show a one ligand/one receptor binding principle. Signals can also be transduced through at least some of the ligands. TNF superfamily ligands are involved in induction of cytokine secretion, upregulation of adhesion molecules, activation antigens and costimulatory proteins, all known to amplify stimulatory and regulatory signals that occur during immune responses. On the other hand, differences in the distribution, kinetics of induction and requirements for induction support the view of a defined role for each of the ligands for T-cell-mediated immune activities. The shedding of members of the TNF receptor superfamily could limit the signals mediated by the corresponding ligands, as a functional regulatory mechanism. Induction of cytotoxic cell death is another common functional feature of this cytokine family (TNF, LT-alpha, CD30L, CD95L and 4-1BBL). Further studies have to identify unique versus redundant biological and physiological functions for each of the TNF superfamily ligands. In addition to other cytokines primary H-RS cell frequently express at least TNF, LT-alpha, CD27L and CD30L, but not CD40L. Furthermore, H-RS cells express several TNF receptors, such as CD30, CD40, CD95, CD120a, CD120b and 4-1BB. The TNF-like ligands might support growth and activation of HD-associated tumor cells and/or interact with surrounding reactive bystander cells, particularly T-cells. The different interactions between H-RS cells and surrounding reactive bystander cells are part of the pathobiology of HD. Detailed functional analysis have to confirm the predicted biological activities of TNF, LT-alpha, CD27L, CD30L, CD40L, CD95L, 4-1BBL and gp34/OX40L for the H-RS cell/T-cell interactions with impact on tumor growth and pathogenesis of HD. TNF and LT-alpha/CD120a and CD120b, CD30/CD30L, and CD40/CD40L are clearly critical elements in the deregulated network of interactive signals between H-RS cells and surrounding bystander cells with membrane-associated and cytokine-mediated events. Several TNFR superfamily members are also candidates for novel treatment protocols, including CD30 and CD40.

We have studied tissue expression of the cytokine receptors using a high sensitivity biotin-streptavidin system on cryostat sections. We used a panel of monoclonal antibodies from the 6th International Workshop on Human Leukocyte Differentiation Antigens, namely CD25 (IL-2R alpha), CD95 (FAS antigen), CD116 (GM CSFR), CD117 (SCFR), CD120 alpha (TNFR I), CD120b (TNFR II), CD121a (IL-1R I), CDw123 (IL-3R), CD124 (IL-4R), CD126 (IL-6R), CD127 (IL-7R), CDw128 (IL-8R), CD130 (gpl130), CD131 (IL-3R), CD132 (IL-2R gamma), CD134 (OC-40), CD135 (FLT3/FLK2). Examined tissues (lymph nodes and spleens) were obtained from 12 patients with folicular non-Hodgkin's lymphoma, periferal T non-Hodgkin's lymphoma, B lymphoma, myeloma, Hodgkin's disease, two cases of T cell rich B-lymphoma, autoimmune haemolytic anemia and two cases of rudimentary trombocytopenic purpura. Our results indicate that immunohistological technology using native tissues on cryostat sections, monoclonal antibodies and the visualisation with biotin-streptavidin is a particularly suitable supplementary staining procedure for detection of the cytokine receptors in tissues.

T cell receptor, accessory molecules, cytokines are important regulatory factors that determine the development and function of T lymphocytes. Among them are also molecules belonging to superfamily of tumor necrosis factor receptor (TNFR) which beside CD30 include CD27, CD40, TNFR-I and -II, Fas (CD95), OX40, 4-1BB (CDw137), nerve growth factor receptor, lymphotoxin-beta receptor, Apo3/DR3/Ws1-1/lymphocyte associated receptor of death, DR4, DR5/TNF-related apoptosis-inducing ligand, osteoprotegerin, and TNFR-related 2. CD30 recognized originally on Reed-Sternberg cells of Hodgkin's lymphoma became of interest in studies of Th1 and Th2 cell differentiation. This paper shows recent findings regarding CD30 expression and its pleiotropic role in T cell function. It provides information about controversial role of CD30 as Th2 cell differentiation marker and gives concise insight into the function of this receptor as a signal transducing molecule.
