Our Science

Homeostasis
Our lab investigates eosinophils, monocytes and neutrophils as first responders in (sterile) inflammation. In order to understand how phagocyte dynamics change in disease it is pivotal to first understand their functions in homeostasis. We use cutting edge techniques such as deuterated glucose labeling in humans to determine phagocyte production, migration and death in blood, bone marrow and peripheral tissues in both health and inflammation.

Physical trauma 
Upon physical trauma neutrophils can quickly recognize and signal damage as well as combat penetrating pathogens. A fully automated flow cytometer called the AQUIOS enables the quick measurement of neutrophil subtypes and activation without the requirement of trained personnel. These insights can predict disease severity, the susceptibility to infections and aid to personalize treatment.


Lung inflammation
Our lab investigates eosinophils, monocytes and neutrophils as first responders in (sterile) inflammation. These phagocytes can quickly recognize and signal danger as well as combat pathogens. Inflammatory diseases the lab focuses on are (long) COVID, asthma, COPD and cystic fibrosis.

We can use these fast responding cells to biomonitor the inflammatory status of the patient even at point-of-care. A fully automated flow cytometer called the AQUIOS enables the quick measurement of these cells without the requirement of trained personnel. These insights can predict the status of a disease, the susceptibility to infections and aid to personalize treatment.

Microplastics
A recent innovative research line studies the response of phagocytes to environmental microplastics

Our tools


Glucose labeling of human innate immune cells
In order to unravel human phagocyte dynamics in both health and inflammation we use deuterated glucose labeling to determine phagocyte production, maturation, migration and death in blood, bone marrow and peripheral tissues.

  • Deuterated glucose molecuul

Intravital 2PM microscopy
We visualize phagocyte migration longitudinally in living mice using 2-photon microscopy.

Microfluidics and 3D gels
We visualize human phagocyte migration in 3D matrices and microfluidics. For instance to understand whether the typical lobular nucleus of a neutrophil and eosinophil aids in squeezing through narrow pores, but also to compare migration of different neutrophil subsets. In addition, we visualize how phagocytes migrate towards bacteria versus microplastics and  investigate whether the phagocytosis of microplastics influences human neutrophil migration.

Automated point-of-care flow cytometry
A fully automated flow cytometer called the AQUIOS enables the quick measurement of eosinophils, monocytes and neutrophils without the requirement of trained personnel. We can use these fast responding cells to biomonitor the inflammatory status of the patient even at point-of-care.
