Next phase of cancer immunotherapy - Targeting the Tumor Stroma

Tumor development and progression are dependent on the cross talk between tumor cells, stromal cells, immune cells and the extracellular matrix (ECM). The TME consists of various cells such as myeloid derived suppressor cells (MDSCs), Tumor Associated Macrophages (TAMs) and Regulatory T cells (Tregs) and Cancer associated fibroblasts (CAFs) that contribute to immune cell dysfunction in the TME.

Tumor cells interact with the stroma and ECM leading to a remodeling of the tumor environment into a hypoxic and metabolically active state. In addition, tumors interact with immune cells promoting inflammatory responses that maintain tumor metastasis. Fibroblasts and other stromal cells in turn secrete cytokine responses to recruit immune cells thereby contributing to tumor metastasis.

In TME cancer cells directly interact with both the immune system and the stroma and in turn the stroma responds with pro-inflammatory and anti-tumor makers.

We aim to understand the interactions between stroma-cancer cells and immune system.

Modules in IO

  • Immune 3D can be used to assess factors that increase immune cell migration and infiltration, reduce the production of inhibitory factors and the recruitment of suppressive cells, modulate cellular adhesion, integrins, chemokines and nutrient availability.
  • Immune 3D can be used to assess factors that increase immune cell migration and infiltration, reduce the production of inhibitory factors and the recruitment of suppressive cells, modulate cellular adhesion, integrins, chemokines and nutrient availability.
  • Our system can be used to assess factors modulating immune cell function, such as immune checkpoints or inhibitor receptor expression.
  • Spatial/ temporal relationships between immune cells, tumor cells and surrounding stroma.
  • Immune 3D can be set in the presence and absence of immune cells providing a reproducible and affordable platform (compared to in vivo systems) to assess the impact of specific compounds on the tumor microenvironment and the relative contribution of the immune system.
  • Importantly, the impact of specific compounds on human tumors and human immune cells can be observed and characterized.
  • Immune 3D can be used in combination with immune suppressive agents such as chemotherapy, pharmacological inhibitors, as well as with cells that have been genetically manipulated in order to elucidate the mechanisms impacting anti-tumor immunity.
  • Our system provides a novel platform to assess synthetic lethality and the impact of targeting defective DNA repair in cancer cells on anti-tumor immunity.
