The transcription factor hepatocyte nuclear factor 1beta (HNF1beta) is a tissue-specific regulator that also plays an essential role in early development of vertebrates. In humans, four heterozygous mutations in the HNF1beta gene have been identified that lead to early onset of diabetes and severe primary renal defects. The degree and type of renal defects(More)
The activity of natural killer (NK) cells is regulated by surface receptors, which direct target cell recognition. NKp30 (Natural Cytotoxicity Receptor 3) induces target cell lysis and is also crucial for the interaction with dendritic cells. So far, the cellular ligands for NKp30 have remained elusive. Here we show that the nuclear factor HLA-B-associated(More)
AFM13 is a bispecific, tetravalent chimeric antibody construct (TandAb) designed for the treatment of CD30-expressing malignancies. AFM13 recruits natural killer (NK) cells via binding to CD16A as immune effector cells. In this phase 1 dose-escalation study, 28 patients with heavily pretreated relapsed or refractory Hodgkin lymphoma received AFM13 at doses(More)
NKp30, a natural cytotoxicity receptor expressed on NK cells is critically involved in direct cytotoxicity against various tumor cells and directs both maturation and selective killing of dendritic cells. Recently the intracellular protein BAT3, which is involved in DNA damage induced apoptosis, was identified as a ligand for NKp30. However, the mechanisms(More)
The tissue-specific transcription factor HNF1alpha is expressed in kidney, liver, intestine and stomach of Xenopus. We show that the HNF1alpha gene is transcriptionally activated at the onset of zygotic gene transcription and that this transcription is maintained throughout development. Ectodermal explants of blastulae (animal caps) express HNF1alpha mRNA(More)
Drosophila enhancer of rudimentary [e(r)] interacts genetically with the rudimentary gene, which encodes a protein possessing the first three enzymatic activities of the pyrimidine biosynthesis pathway. A regulatory or enzymatic activity of e(r) in pyrimidine biosynthesis and the cell cycle has been suggested, but nothing is known about its molecular(More)
Natural killer (NK) cells are a major component of the anti-tumor immune response. NK cell dysfunctions have been reported in various hematologic malignancies, including chronic lymphocytic leukemia (CLL). Here we investigated the role of tumor cell-released soluble and exosomal ligands for NK cell receptors that modulate NK cell activity. Soluble CLL(More)
Dendritic cell-derived exosomes (Dex) are small extracellular vesicles secreted by viable dendritic cells. In the two phase-I trials that we conducted using the first generation of Dex (IFN-γ-free) in end-stage cancer, we reported that Dex exerted natural killer (NK) cell effector functions in patients. A second generation of Dex (IFN-γ-Dex) was(More)
Since mid-1990s, the field of cancer immunotherapy has seen steady growth and selected immunotherapies are now a routine and preferred therapeutic option of certain malignancies. Both active and passive cancer immunotherapies exploit the fact that tumor cells express specific antigens on the cell surface, thereby mounting an immune response specifically(More)
