Structural biology of immunity, inflammation and cancer

We employ integrative structural biology to study the structure and mechanism of proteins and protein complexes pivotal to immunity, inflammation, and cancer. Over the years our research group has taken a leading role in the elucidation of cytokine-receptor complexes and in the development of protein-based antagonists against complexes of biomedical importance. The cornerstone of our research philosophy lies in a rigorous hypothesis-driven interrogation of the proteins and protein assemblies under study, and is firmly nested in collaborations with leading academic research groups in Belgium and abroad as well as industrial partners. Several of our projects include extensive activities in translational science.

Currently, our research team is actively investigating the following research areas:

• Extracellular and intracellular signaling protein assemblies in immunity, inflammation, cancer.

• Structural and mechanistic principles underlying oncogenic receptor tyrosine kinases and their protein ligands.

• Structure-based drug design against protein-protein interactions.

In vivo protein crystals and protein phase transitions in immunity, inflammation, and cancer.
