Research focus

​Inflammation is a protective response to induce repair in conditions of cellular damage and stress. However, defective regulation of inflammatory reactions can lead to chronic inflammation and the development of disease, indicating the need for tight control of inflammatory processes. Our research aims to understand the in vivo mechanisms by which chronic inflammation drives (autoimmune) pathology.

One major focus concerns the transcription factor NF-kB and the molecular mechanisms by which NF-kB controls inflammatory and apoptotic responses in vivo. Also ER stress and autophagy are being studied in this context, since more and more evidence indicates that also these pathways may be crucially involved in inflammatory reactions and the development of inflammatory pathology. For these studies we use transgenic mice as a model to study gene function in vivo, both through Cre/LoxP-mediated gene targeting allowing tissue-specific gene deletion, and through CRISP/Cas technology to introduce specific mutations in vivo. These mice are characterized in several mouse models of chronic inflammatory pathology, including models for inflammatory bowel disease, rheumatoid arthritis, diabetes, and multiple sclerosis.

A protein that controls inflammation

17/03/2020 - A study by the research team of Geert van Loo (VIB-UGent Center for Inflammation Research) has unraveled a critical molecular mechanism behind autoimmune and inflammatory diseases such as rheumatoid arthritis, Crohn’s disease, and psoriasis.

Linking wound healing and cancer risk

26/11/2019 - When our skin is damaged, a whole set of biological processes springs into action to heal the wound. Now, researchers from VIB-UGent have shown that one of the molecules involved in this, HMGB1, slows down wound healing.

Preventing cell death as novel therapeutic strategy for rheumatoid arthritis

10/05/2019 - A study by research groups from the University of Cologne, VIB, Ghent University, the Βiomedical Sciences Research Center ‘Alexander Fleming’ in Athens & the University of Tokyo identified a new molecular mechanism causing rheumatoid arthritis.

Defect in A20 gene expression causes rheumatoid arthritis

16/08/2011 - In Nature Genetics, VIB-UGent researchers demonstrate that a defect in the expression of the A20 gene can contribute to the development of rheumatoid arthritis in mice, identifying A20 as a target for the generation of new drugs.

First step to new therapy for chronic bowel disease

05/07/2010 - Scientists associated with VIB and Ghent University (UGent) have discovered that A20 protein plays an important protective role in diseases associated with chronic bowel inflammation.
