Zentrale Fragestellung

How can multiparametric imaging be further developed to achieve quantifiable visualization of functional, molecular and immunological mechanisms of tumors and ultimately guide new therapeutic approaches?

Approach

Building upon our established PET tracer development program, we now aim to develop new senescence-detecting imaging probes with increased sensitivity and specificity, ultimately also as a theranostic approach. Design of experiment (DoE) methods have been successfully established and were applied for efficient tracer development. DoE will be utilized for a swift and flexible adjustment of iFIT tracer candidates in close interaction with the medicinal chemistry groups in the FIMT area. The iFIT nanobody-based immune and metabolic imaging pipeline will be further advanced and used in synergy with multiparametric and multiscale imaging to unravel how tumor cell-intrinsic stress impacts the TME and anti-tumor immune responses. The comprehensive iFIT imaging program utilizes AI to enable advanced image analysis and ultimately guide novel therapeutic approaches.  Research Area C is coordinated by Christian la Fougère, Bernd Pichler and Bettina Weigelin.

The research area "Molecular and Functional Multiparametric Imaging" (MFMI) is divided into four research modules:
  • MFMI-1: Imaging of Cancer Stress and Metabolism
  • MFMI-2: Multiscale Immune-Imaging - from the Microenvironment to the System
  • MFMI-3: New Theranostics Approaches and Refining Established Concepts
  • MFMI-4: Methodological Imaging and Data Analysis Platform



MFMI-1

The radiopharmaceuticals are radiolabeled in the radiopharmacy of the Werner Siemens Imaging Center under a manufacturing license and in compliance with "Good Manufacturing Practice" (GMP) regulations. The regulations guarantee strict quality assurance in the manufacture of pharmaceuticals.

Within MFMI-1, we will develop a new generation of radionuclide-based PET tracers to image cancer stress states and stress responses. In the next iFIT funding period, we aim to synthesize and evaluate new libraries of self-immolating β-galactosidase substrates with improved pharmacokinetics and sensitivity. The new senescence probes can be easily functionalized with peptides and other pharmacokinetic modifiers to allow for tissue specificity and better tracer performance. With our expertise, we are well-equipped to untangle the complex interplay of senescent tumor cells and the immune system and vice versa the immune system’s role in modulating senescence.

MFMI-2

The main objective within the second iFIT funding term is to enhance the integration between systemic macroscopic and cellular microscopic immune imaging. The comprehensive immune imaging pipeline, including CAR-T cells, will be further developed. Next generation radiolabeling approaches will be explored to enable quantitative immune cell tracking and detection of immune cell networks in vivo in both, animal models of cancer and humans.

Intravital microscopy can be used to assess the success of cancer immunotherapies such as CAR-T cell therapy and even to monitor the function of individual CAR-T cells in the tumor live in order to further improve the design of CAR-T cells.

MFMI-3

Research at the interface between machine learning and medicine: Among other things, artificial intelligence is being used to investigate how medical images can be analyzed faster and better.

Our MFMI-3 work program combines the competence of FIMT, ImmT, and MFMI to advance theranostic concepts i) by developing new theranostics against novel targets, and ii) by exploring strategies to overcome resistance mechanisms in primary tumors and metastases using combination therapies.

MFMI-4

A successful imaging science program relies on innovative state-of-the-art hardware infrastructures, software tools as well as advanced imaging and data analysis workflows. In the next funding period, we will go a step further and implement the UT CODEX platform of Christian Schürch to the imaging science center to serve iFIT projects in an optimal way providing microscopic and macroscopic molecular and functional information. iFIT provides all hardware imaging systems and analysis tools, resulting in a gigantic volume of data from different origin, size and format. To reveal essential information of interconnected in vivo and ex vivo multimodal imaging, advanced data mining and analysis, machine learning and artificial intelligence approaches are implemented.
