IMPORTANCE The prognosis of advanced cutaneous T-cell lymphoma (CTCL), including Sézary syndrome and mycosis fungoides (MF), is poor. So far, no curative option apart from allogeneic stem cell transplantation is available. Large cell transformation often hallmarks cases with a more aggressive clinical course, and large tumor cells may express CD30. Recently, brentuximab vedotin, a conjugate of ...

ALK+ anaplastic large cell lymphoma (ALCL). frequently carries the t(2;5).(p23;q35). resulting in expression of NPM-ALK oncogenic kinase, which is capable of activating multiple oncogenic pathways. ALK+ ALCL is also characterized by overexpression of CD30 receptor, a member of the tumor necrosis factor (TNF). receptor superfamily, which has been targeted for therapy using conjugated anti-CD30 a...

Changes in the serum level of the soluble form of CD30 (sCD30) in a patient with adult T-cell leukemia/lymphoma were monitored throughout the indolent phase, acute crisis, and relapse. The level of sCD30 was elevated prior to the development of laboratory data abnormalities. In addition, the elevated sCD30 level was associated with clinical manifestations in the lung, including malignant pleura...

T-cell lymphomas are aggressive lymphomas with decreased prognosis and resistance to therapy. BAG-3 and heat shock protein 70 (HSP70) function in chemotherapeutic resistance and cellular survival. Expression of BAG-3 has not been investigated in T cell lymphomas. We investigated fifty cases including benign, systemic and cutaneous T cell lymphomas. Benign T cells were negative for BAG-3 and HSP...

The aim of this study was to improve the level of diagnosis and differential diagnosis of lymphomatoid papulosis (LyP). Two cases of type B LyP were identified and the literature was reviewed to summarize the clinical outcomes and pathology of LyP and its treatment. The two patients exhibited symptoms with papulonodular lesions, the centers of which gradually underwent ulceration and necrosis. ...

CD30 and OX40 (CD134) are members of the TNFR superfamily expressed on activated CD4 T cells, and mice deficient in both these molecules harbor a striking defect in the capacity to mount CD4 T cell-dependent memory Ab responses. This article shows that these mice also fail to control Salmonella infection because both CD30 and OX40 signals are required for the survival but not commitment of CD4 ...

hiPSC derivation and selection remains inefficient; with selection of high quality clones dependent on extensive characterization which is not amenable to high-throughput (HTP) approaches. We recently described the use of a cocktail of small molecules to enhance hiPSC survival and stability in single cell culture and the use of flow cytometry cell sorting in the HTP-derivation of hiPSCs. Here w...

Although strategies that block FOXP3-dependent regulatory T cell function (CTLA4 blockade) and the inhibitory receptor PD1 have shown great promise in promoting antitumor immune responses in humans, their widespread implementation for cancer immunotherapy has been hampered by significant off-target autoimmune side effects that can be lethal. Our work has shown that absence of OX40 and CD30 cost...

The CD30-targeting Ab-drug conjugate brentuximab vedotin (SGN-35) was recently approved for the treatment of relapsed Hodgkin lymphoma and anaplastic large-cell lymphoma by the Food and Drug Administration. In the present study, we report the experience of the German Hodgkin Study Group with brentuximab vedotin as single agent in 45 patients with refractory or relapsed CD30(+) Hodgkin lymphoma ...

The leukocyte activation marker CD30 is highly expressed on the Reed Sternberg cells of Hodgkin's disease (HD). On normal tissues, CD30 has a restricted expression profile limited to activated T cells, activated B cells, and activated natural killer cells. This expression profile makes CD30 an ideal target for monoclonal antibody (mAb)-based therapies of Hodgkin's disease. CD30 mAbs have been s...
