TY - JOUR A1 - Wajant, Harald T1 - Molecular mode of action of TRAIL receptor agonists—common principles and their translational exploitation JF - Cancers N2 - Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its death receptors TRAILR1/death receptor 4 (DR4) and TRAILR2/DR5 trigger cell death in many cancer cells but rarely exert cytotoxic activity on non-transformed cells. Against this background, a variety of recombinant TRAIL variants and anti-TRAIL death receptor antibodies have been developed and tested in preclinical and clinical studies. Despite promising results from mice tumor models, TRAIL death receptor targeting has failed so far in clinical studies to show satisfying anti-tumor efficacy. These disappointing results can largely be explained by two issues: First, tumor cells can acquire TRAIL resistance by several mechanisms defining a need for combination therapies with appropriate sensitizing drugs. Second, there is now growing preclinical evidence that soluble TRAIL variants but also bivalent anti-TRAIL death receptor antibodies typically require oligomerization or plasma membrane anchoring to achieve maximum activity. This review discusses the need for oligomerization and plasma membrane attachment for the activity of TRAIL death receptor agonists in view of what is known about the molecular mechanisms of how TRAIL death receptors trigger intracellular cell death signaling. In particular, it will be highlighted which consequences this has for the development of next generation TRAIL death receptor agonists and their potential clinical application.

T1 - Denileukin Diftitox plus Total Skin Electron Beam Radiation in Patients with Treatment-refractory Cutaneous T-cell Lymphoma (Mycosis Fungoides): Report of Four Cases JF - Acta Dermato-Venereologica N2 - Mycosis fungoides (MF) is the most common cutaneous T-cell lymphoma (CTCL) (1). Most patients initially respond well to standard therapy, but advanced MF is often treatment refractory. Thus, a combination of the available treatment options is an important strategy. Total skin electron beam radiation (TSEB) is effective in MF, with a complete remission rate of up to 90% in the early stages. However, in patients with more advanced stages, remission rates are considerably lower (2, 3). Denileukin diftitox (DD) (Ontak®) is a recombinant fusion protein of the receptor-binding domain of interleukin (IL)-2 and the enzymatic and translocation domains of diphtheria toxin (4). It targets the alpha-subunit of the IL-2-receptor (CD25). There are no reports on this combination therapy in MF.
