A CD30 ligand (CD30L; CD153) and its receptor, CD30, is a membrane-associated glycoprotein belonging to the TNF superfamily and TNFR superfamily. These were expressed preferentially by activated CD4(+)T cells. In this paper, we show that CD44(low)CD62(hi)CD4(+) T cells from CD30L(-/-) or CD30(-/-) mice exhibited impaired differentiation into Th17 cells but an increased ability to produce IL-2 a...

CD30 is a costimulatory receptor on activated lymphocytes and a number of human lymphoma cells. Specific ligation of membrane-bound CD30 or cellular stimulation by PMA results in a metalloproteinase-mediated down-regulation of CD30 and release of its soluble ectodomain (sCD30). In this report, it is demonstrated that PMA-induced CD30 cleavage from Karpas 299 cells was mediated by a membrane-anc...

In this report, we identify an important function for CD30 signals in the effective segregation of B and T lymphocytes in the murine spleen, additional to the recognized requirement for lymphotoxin signals. We show that CD30 signals are not required for transcription or protein expression of homeostatic chemokines, but CD30-deficient mice display impaired B/T segregation. This defect correlates...

BACKGROUND AND PURPOSE Atopic diseases are thought to be associated with cytokine-mediated immune dysregulation, for example, a T helper cell type 1/2 (Th1/Th2) imbalance. CD30 is proposed to be one of the surrogate markers for Th2 immunity. In this study, we investigated whether CD30 is a good marker for atopy and Th2 predominance in a pediatric population. METHODS This study included 61 chi...

T cell apoptosis is associated with defective cell-mediated effector functions in several infectious diseases. In tuberculosis, there is evidence that T cell apoptosis may be cytokine mediated, but the mechanisms are not clearly understood. Type 2 cytokines have recently been associated with disease extent in human tuberculosis, but they have not previously been linked to apoptosis in mycobacte...

Members of the TNF receptor (TNFR) superfamily are cell-surface proteins that can be found on most cell types including lymphocytes. Although some TNFR-related molecules are constitutively expressed, others, such as CD30 and Ox40, are induced upon activation of lymphocytes. CD30 and Ox40 are predominantly expressed on activated T helper (T(h))2 cells. Both receptors can activate c-Jun N-termina...

Members of the tumor necrosis factor receptor superfamily play an important role in the initiation, expansion, and termination of an immune response. It has recently been demonstrated that one member of this family, CD30, plays a central role in maintaining peripheral tolerance by controlling the expansion of autoreactive CD8 T-cells. In the present study, Cd30 was mapped to a 5.6-cM interval o...

NPM-ALK chimeric transcripts, encoded by the t(2;5), lead to an aberrant expression of ALK by CD30+ systemic lymphomas. To determine if t(2;5) is involved in cutaneous lymphoproliferative disorders, we studied 37 CD30+ cutaneous lymphoproliferations, 27 mycosis fungoides (MF), and 16 benign inflammatory disorders (BID). NPM-ALK transcripts were detected by nested reverse transcription-polymeras...

Several non-Hodgkin lymphoma (NHL) subtypes, including diffuse large B-cell lymphoma (DLBCL), variably express CD30. This phase 2, open-label study evaluated the efficacy of brentuximab vedotin, an anti-CD30 antibody-drug conjugate, in relapsed/refractory CD30(+) NHL. This planned subset analysis of B-cell NHLs includes 49 patients with DLBCL and 19 with other B-cell NHLs. Objective response ra...
