DUCHÊNE MEGENS LAB

The main objective of our research is to uncover novel molecular mechanisms that control inflammation and immune responses.

Inflammation is a natural immune response triggered by harmful stimuli, such as infections or injuries. Its primary function is to protect the body against potential threats and to promote the healing of damaged tissue. Nevertheless, when inflammation is dysregulated and becomes chronic, it can contribute to the pathogenesis of many diseases. Inflammation is a complex mechanism involving the tightly orchestrated action of multiple inflammatory molecules.

During the inflammatory response, chemokines govern the recruitment of circulating leukocytes and their migration to the inflamed sites. The effects of chemokines are mediated by G-protein coupled receptors (GPCRs), which are expressed in a wide range of immune cell types. Besides these "conventional" receptors (CCRs and CXCRs), chemokines also bind to atypical chemokine receptors (ACKRs), which control the availability of chemokines within tissues and thus influence immune cell behavior. The experimental work in our lab mainly focuses on the biology of ACKRs.
