EU Grant for Dennis Beringer (Group Kuball)

Dennis Beringer, Kuball Group, received a EU Marie Curie MSCA fellowship:
“Investigating the recognition of a novel ligand by gamma-delta T cells and the translation of this interaction into molecules for future cancer immunotherapy”.
Congrats Dennis!

A relevant part of the abstract:
“Gamma-delta (gd-)T cells are a fast acting subset of T cells that recognize a wide variety of ligands. In contrast to alpha-beta T cells they are not restricted to classical peptide-MHC antigens. Our preliminary data on a gd-T cell clone shows selective recognition of tumour cells mediated through a novel ligand.
The aims of this action are; 1) elucidating the molecular mechanism of the gd-T cell receptor (TCR) recognizing the novel ligand on cancer cells and 2) generating therapeutic agents for cancer cells.
A multidisciplinary approach will be used to unveil the interaction of the gd-TCR with its ligand.  The results generated in this part of the action will increase the current knowledge regarding gd-T cell ligands.”

Grant Dutch Cancer Society for Niek van Til

Grant Dutch Cancer Society for Niek van Til

Niek van Til (Boelens/Nierkens group) received a KWF grant (Dutch Cancer Society) for his project:

Development of superior Wilms’tumor 1 specific gene modified CORD BLOOD T cells to treat refractory acute myeloid leukemia patients.

Pediatric acute myeloid leukemia (AML) is a type of cancer that can be treated by transplanting blood stem cells. Even though this treatment is curative in some patients, unfortunately, the cancer often reappears later in life. In the pediatric blood and marrow transplantation program” at the UMC Utrecht, we use donor umbilical CORD BLOOD cells as a source of stem cells for transplantation. The KWF project is designed to enhance the development of cord blood-derived tumor specific T cells to eliminate the leukemic cells. To achieve this we will use techniques to modify the genetic content of T cells in a safe and permanent manner. We expect that the findings result in a broad applicability of effective allogeneic off-the-shelf T cell therapies extending also to other types of cancers in both children and adults.

Jurgen Kuball on what's new in blood and bone marrow transplantation

Jurgen Kuball on what's new in blood and bone marrow transplantation

In the Video Journal of Hematological Oncology, Jürgen Kuball, MD, PhD from the University Medical Center, Utrecht (the Netherlands), presents this week some key messages on transplantation which he believes are important in this field at present. Dr Kuball starts by discussing the huge variability in transplant products which are infused in to patients today which he believes to be hugely neglected though it is recognised that this has an impact on patient impact. Dr Kuball goes on to discuss how drugs can be used to ensure patients do not develop graft versus host (GVD) after transplantation based on the patient’s immune constitution. Highlighting the importance of identifying smaller, smarter trials to test such drugs, Dr Kuball believes this is necessary in order to rapidly progress in this field. The item was recorded at the International Transplant Course which was held at the 2016 congress of the European Society for Blood and Narrow Transplantation in Barcelona, Spain.

Confusion between the FcR gamma chain and the cytokine receptor gamma chain

 

As a scientist in the field of Fc receptors and Immunology for more than 20 years I often notice the confusion between the FcR gamma chain and the cytokine receptor gamma chain. I sometimes get requests from students for the common gamma chain, whereas the FcR gamma chain is meant, or scientist order wrong knockout mice. To end this confusion, we have written this letter to Immunity on the structure and function of cytokine receptors and signaling via the common gamma chain and compare this to the activating Fc receptors and the signaling by the Fc receptor associated gamma chain. Both gamma chains share some signaling pathways, but in sequence, function, cellular distribution, and chromosome location they diverge.

With this letter we hope we can end the confusion about the FcR gamma versus the common gamma chain, and would appreciate it very much if you could indicate the FCER1G encoded protein with Fc receptor gamma chain (FcRg) in all of your publications.

Press Release: Gadeta closes EUR 7 million Series A financing to advance novel cancer immunotherapies to the clinic

Utrecht, the Netherlands – March 29, 2016 - Gadeta B.V., a Dutch start-up company focused on the discovery and development of novel cancer immunotherapies based on gamma delta (γδ) T cell receptors, announced today the completion of a EUR 7 million Series A financing round led by Baxalta Ventures and Medicxi Ventures. Founders, management and Utrecht Holdings also participated. Geeta Vemuri from Baxalta Ventures and Michèle Ollier and Giovanni Mariggi from Medicxi Ventures will join the supervisory board. The company was founded by Dr. Jürgen Kuball, Mark de Boer, Utrecht Holdings and Medicxi Ventures (which provided seed capital).

 

Gadeta’s technology platform is based on the ground-breaking discoveries of Prof. Dr. Jürgen Kuball regarding the role of γδ T cell receptors in the broad recognition of the metabolic differences in hematological and solid tumor cells, and their potential use for the treatment of advanced malignancies. Dr. Kuball, co-founder and chief scientific officer of Gadeta, chairs the section of applied & tumor-immunology within the laboratory of translational immunology at the University Medical Center Utrecht (UMC Utrecht), as well as the Department of Hematology (adults), and is the Director of the Bone Marrow Transplantation Program at the UMC Utrecht.

 

Mark de Boer, co-founder and acting CEO of Gadeta, said: “Supported by the Series A financing, we’re excited to accelerate our programs and rapidly advance them to the clinic. With its unique ability to target the metabolic changes in tumor cells, the strong therapeutic potential of our platform holds tremendous promise for the treatment of hematological and solid tumors.”

 

Gadeta expects to start a Phase I/IIa clinical trial of its lead program in acute myeloid leukemia (AML) in early 2017. In parallel, the company intends to optimize a closed manufacturing system to allow for the start of a second clinical trial in solid tumors later in 2017

 

About Gadeta

Founded in 2015, Gadeta has developed a technology platform based on combinatorial T Cell receptor exchange (CTE) to create optimized gamma delta (γδ) T-cell receptors (TCRs) with an enhanced anti-cancer reactivity. Gadeta’s new cell-based anti-cancer product called T Cells Engineered To Express A Defined Gamma Delta TCR (TEGs) has strong therapeutic potential for combating and eradicating both hematological and solid tumors. This approach utilizes high-affinity γδ TCRs expressed on αβ T cells with superior proliferation capacity. For more information: www.gadeta.nl.

Two new PhD students in group Boelens/Nierkens!

We are more than happy to introduce to you Jurgen Langenhorst and Celina Szanto. Jurgen and Celine are 2 new PhD-students, who recently joint our group. We really look forward to work with them in upcoming years. Jurgen will work on pharmacokinetics and pharmacodynamics of Fludarabine, and Celina will unravel the functional dynamics of the immune system in neuroblastoma patients. Please read the short bio’s + recent photo's below.

CELINA SZANTO

My name is Celina Szanto and I’m a PhD student in de lab of Jaap Jan Boelens and Stefan Nierkens. After obtaining my high school degree at Gymnasium Beekvliet in Sint-Michielsgestel, I went to Leuven (Belgium) to study Biomedical Sciences. After a broad bachelor I continued my master in Biomedical Sciences with a strong focus on genetics.

During my master thesis in de Laboratory of Reproductive Genomics at the KU Leuven I performed single-cell sequencing to study genomic instability in breast cancer and human embryos. Here I discovered my passion for research and decided to start my PhD in the Netherlands. My interest for tumor immunology started during a short internship in the Laboratory of Pediatric Immunology at the KU Leuven.

With a broad scientific background I hope to increase the survival changes of Neuroblastoma patients by unraveling the functional dynamics of the immune system. In addition, we will investigate the pharmacokinetic and pharmacodynamics properties of anti-GD2 (dinutuximab) in Neuroblastoma patients in relation to efficacy versus toxicity.

I’m always open for new ideas! If you are interested, feel free to contact me via LinkedIn: https://www.linkedin.com/in/celinaszanto

JURGEN LANGENHORST

In 2005 I started my studies at the Utrecht University school of pharmacy. From the beginning on I combined studying with a rowing career starting at the national level, but growing towards internationalcompetition later on. Besides high performance sports a common theme during my studies was oncology. It started with fundamental research regarding development of temperature sensitive liposomes loaded with doxorubicin followed by another internshipwhere I implemented a new radiopharmaceutical for imaging of Neuro-Endocrine tumors in a hospital setting. After finishing my studies I started working as a pharmacist in the UMC Utrecht at the preparation department, where among others cytostatic drugs are prepared.

I hope to combine my knowledge of cancer and chemotherapy with my mindset derived from sports,  towards aiding in improving dosage of fludarabine in stem cell transplantations.
