Project description
A novel B-cell immunotherapy
B lymphocytes exhibit diverse immunological functions, including antibody production and antigen presentation. Emerging evidence indicates that these cells also create niches known as B cell-associated tertiary lymphoid structures (TLS) that sustain an immune response. The role of TLS in cancer is only beginning to emerge, and understanding it requires further insight into cellular and spatial composition. Funded by the European Research Council, the BeaT-IT project aims to determine the factors that stimulate B cells and induce TLS. Researchers will employ novel polymeric biomaterials and test different agents and cells for their capacity to stimulate TLS formation. The materials can be further combined with immunotherapy or chemotherapy as a synergistic anticancer strategy.
Objective
Recent clinical evidence points to a potential new direction in immuno-oncology: utilizing B cells and B cell-associated tertiary lymphoid structures (TLS). B cells display diverse immunological actions, including antibody production, antigen presentation, cytokine secretion and TLS induction. They have a dual role: they can initiate and reinforce anti-cancer immunity but B cells can also acquire regulatory phenotypes. To open up a new immunotherapeutic paradigm, I aim to understand how to optimally activate B cells, using nano-/biomaterials which load and precisely release a variety of agents to stimulate B cells and to suppress B cell regulatory phenotypes. Furthermore, I will manufacture porous scaffolds based on injectable microgels or via 3D printing with microgel fibers to induce TLS formation. The scaffolds with tunable porosity will allow B cells and other immune/stromal cells to infiltrate, arrange and expand, and soluble factors to diffuse. Moreover, the scaffolds can be easily functionalized with different chemical cues to stimulate B cells for TLS formation, such as CXC-chemokine ligand 13 and interleukin-7. This will help us understand TLS induction. Importantly, I will use ex vivo engineered TLS to study what microenvironmental factors influence their functionality. Subsequently, in vivo formation of B cell-associated TLS will be induced by the scaffolds. B cell activation and TLS induction will be combined for tumor therapy, and potential abscopal effect of the treatment to address metastases will be studied. The materials will be further combined with checkpoint inhibitors and chemotherapy to reach synergism. In addition, the new therapeutic strategies will be tested in patient-derived tumors established in humanized mice. BeaT-IT aims to understand optimal B cell activation and TLS formation with nano-/biomaterials to establish a new direction in immuno-oncology, which is anticipated to realize an upcoming breakthrough in cancer immunotherapy.
