B cell malignancies
​
Research aim
Our research aim is to control cellular life and death decisions to improve treatment of B cell cancers and allow T cell immunotherapy for untreatable cancers.
​
About us
The background of our research concerns cell death regulation in T and B lymphocytes. With previous interests and expertise we developed two main research lines; 1) targeting malignant B cells to improve patient treatment and 2) designing an enhanced killing machinery for engineered T or NK cells. We work in close collaboration between the center for translational immunology (CTI) and hematology department at the UMC Utrecht and combine fundamental research questions with (pre)clinical implementation. Our main focus relates to improving treatment of the incurable plasma cell malignancy multiple myeloma (MM), but we also focus on other B cell malignancies including classical Hodgkin lymphoma (HL), B-cell non-Hodgkin lymphoma (NHL) and amyloid light-chain (AL) amyloidosis. Next to combination therapy with small molecule inhibitors we employ different strategies to enhance effectivity of cellular immunotherapy. As a means to achieve this we use biochemical & cell engineering approaches, animal models and 3D culture with primary material.

About the PI
Victor Peperzak, PhD
Associate professor
Victor obtained his PhD in 2010 at the Netherlands Cancer Institute (NKI) in Amsterdam examining the mechanisms of T cell co-stimulation.
​
He subsequently moved to the Walter and Eliza Hall Institute (WEHI) in Melbourne, Australia, as a postdoctoral fellow to study pro-survival BCL-2 family proteins in healthy B and plasma cells.
This research line was continued at the Academic Medical Center (AMC) in Amsterdam focusing on malignant B cells.
Since 2016 he leads this research team at the UMCU.

Marta Cuenca, PhD
See more
Marta is originally from Spain, where she graduated in Pharmacy and obtained her PhD in Immunology (University of Barcelona). During her PhD, she studied the inhibitory receptor SLAMF3 as a potential target for the treatment of autoimmune diseases and B cell malignancies.
In 2017 she received a postdoctoral grant (Ramón Areces foundation) and joined the group of Victor Peperzak at the UMCU. Here, she developed diverse hydrogel-based culture systems for patient-specific drug sensitivity profiling in multiple myeloma, which can be applied to investigate optimal treatment sequencing strategies.
In 2022 she was awarded a Young Investigator Grant from the Dutch Cancer Foundation (KWF), and her current research focuses on improving CAR-T cell cytotoxicity against hematological cancers.
Besides her research and teaching activities, Marta is an active member of the Early Career Research board at the UMCU.

Benjamin Motais, PhD

Benjamin, originally from France, began his academic journey with an Erasmus MSc internship at the Jagiellonian University of Krakow, where he developed a keen interest in gene engineering.
Following this, he pursued a PhD in the Blood Cancer Research Group at Ostrava, Czechia, where his research focused on developing allogenic natural killer-cell based therapies for hematological cancer.
After completing his PhD in 2023, Benjamin was hired as postdoctoral fellow within the Peperzak group and is currently working on optimizing CAR-T cell therapies based on the team's proprietary OK-tech patent.
Postdoctoral fellow

Dedeke Rockx-Brouwer
See more
After obtaining her BSc degree in 2004, Dedeke has been a research technician in several labs, initially in the field of infectious diseases starting in the Netherlands, but continuing her research overseas in the United States.
In 2014, she returned to the Netherlands to continue her work in vaccine development, but made a switch to the field of oncology in 2019.
She joined the Peperzak group in 2021 where her main focus lies with the project of Marta Cuenca to reveal important pathways that MM cells use to escape therapy and finding ways to target these specific pathways.
