The cytokine TGF-beta in immune cell physiology and cancer

The immune system can be remarkably efficient at eliminating several blood cancers, especially in the context of allogeneic hematopoietic cell transplantation. Unfortunately, tumor and immune cell specific factors limit the full potential of immune based therapies of most malignancies. Our work aims at better defining the mechanisms that modulate the anti-tumor response, especially by studying the cancer microenvironment and the potently immunosuppressive cytokine TGF-β. A second research axis focusses on other determinants of T cell physiology in the context of hematopoietic cell transplantation. 

Human T-cell adoptive immunotherapy

Our laboratory is working on the differentiation and expansion of human T cells in vitro in order to support early phase clinical trials at HMR. To this end we have adapted validated culture systems and are currently developing several strategies in order to both increase the therapeutic potency of ex-vivo expanded T cells and study basic aspects of T-cell biology.
