Hepatocellular carcinoma (HCC) is the most common primary liver cancer and the second leading cause of cancer-related mortality worldwide. It’s an inflammation related cancer which generally develops in a background of chronic liver disease, characterized by continuous immune cell infiltration and release of pro-inflammatory mediators which are involved in malignant transformation. Macrophages dominate the chronic inflammatory microenvironment and aid in the transition of chronic inflammation to neoplastic transformation by the release of pro-inflammatory mediators. In addition, specific tumor-associated macrophages play a key role in tumor progression through the production of cytokines and growth factors involved in tumor growth, metastasis and invasion. One of our research topics include unraveling the contribution of different liver macrophage subsets to tumor initiation and growth and further investigating how we can target those specific macrophage subsets to enhance anti-tumor immunity and/or suppress tumor tolerance by using in vitro and in vivo models as well as human samples.
A major hurdle in cancer research, and biomedical research in general, is translation of results to the clinic. The most commonly used HCC models fail to represent the complex tumor microenvironment, are time consuming and do not allow timely and effective therapy evaluation. Therefore, our focus is set on developing human-based models including relevant orthotopic humanized mouse models and human sample based in vitro/ex vivo systems, essential for future immune-oncology studies and (immuno)therapy evaluation, as a leap forward to precision medicine.
