Research focus:

Our research focuses on BCL11B, a transcription factor involved in thymopoiesis as well as T lymphocyte and NK cell development and their characteristics. Recently, we have shown that BCL11B-depleted and IL-15-stimulated CD8+ T cells gained features of innate cells. These cells of novel type, named induced innate CD8+ T (iiT8) cells, exhibit a repertoire of multiple innate receptors on their surface. When subjected to killing assays, their cytotoxicity exceeded killing activity of control cells against leukemic cells and neuroblastoma spheroids in an antibody-independent and -dependent manner (AICC and ADCC). Therefore, iiT8 cells are assumed to carry an interesting therapeutic potential in adoptive cell transfer, CAR therapy or therapeutic antibody applications.

 

Key techniques:

• modification of primary cells

• retroviral genetic modification for knock-down of genes

• targeted gene knock-out by CRISPR-Cas9 RNP

• siRNA-mediated expression modulation and vectorbased overexpression

• flow cytometric characterization of manipulated (T-) cells

• functional readout by in vitro killing assays

• in vivo models of human tumor in immunodeficient mice
