Research interests
The Grootjans Lab studies the interplay between the immune system and gastrointestinal cancers.
The lab has three major research lines:
1. Understanding how immune cell alterations in the background of chronic intestinal inflammation (inflammatory bowel disease) favor the development of colorectal cancer;
2. Finding novel immunomodulatory treatment targets for difficult-to-treat cancers such as peritoneal metastasized disease, by better understanding the tumor immune environment;
3. Uncovering the mechanisms driving immune-related adverse events of currently used immune-activating therapies (immune checkpoint inhibitors).
Specialisation
cancer immunology, peritoneal metastases, tumor immune environment, inflammatory bowel disease, colorectal cancer, gastric cancer
