Pediatric rheumatology

Pediatric rheumatology

Our research aims at improving the knowledge regarding disease-causing mechanisms active during rheumatic diseases in children as well as in adults. The obtained knowledge forms a basis for the development of new, targeted anti-rheumatic therapy. We are especially interested in the group of self-molecules termed Alarmins. These are molecules with defined functions inside cells and a common function outside of cells; to alert the body to danger, cell death or cell stress due to infection or trauma, and induce an inflammatory response. A prototype alarmin is HMGB1 and we are studying its inflammation-inducing features, its role in rheumatic diseases and it’s potential as a target for new therapy. 

Our research programme can be divided into three related projects:

1. Studies of the proinflammatory functions of HMGB1 and their regulation

2. The role of HMGB1 in the immunopathogenesis of juvenile idiopathic arthritis (JIA). To perform these studies we have established a biobank (JABBA) of patient samples coupled with a quality register, Swedish Pediatric Rheumatology Registry, and are using molecular, cellular and in vitro/in vivo models.

Additionally we are also interested in studying the role of HMGB1 in other inflammatory conditions, including stroke and have an ongoing project (COUNTERSTROKE) to identify HMGB1 inhibitors that could be used in therapy.
