The Immunotoxicology group
The Immunotoxicology group examines fundamental processes involved in immunosensitization and inflammatory responses by various agents, including drugs, environmental chemicals/pollutants and food components. Knowledge obtained will help to define early indicators of immunosensitizing potential of compounds (e.g. pharmaceuticals or new foods) that can be included in new and existing predictive models. In addition, this knowledge also contributes to development of prophylactic or therapeutic measures.

Ongoing projects:
1. Therapeutic approaches for food allergy
2. Mechanisms of drug hypersensitivity and immune-mediated liver injury

Current research group:
Raymond Pieters (Associate professor, Group Leader)
Marianne Bol-Schoenmakers (Scientist)
Joost Smit (Scientist)
Lydia Kwast (PhD student)
Veronica Schulz (PhD student)
Rob Bleumink (Technician)
Manon van Roest (Technician)
Laura Kruijssen (Technician)
