Take the bitter with the sweet; Targeting hyperglycosylation of the auto-antibodies specific for rheumatoid arthritis.

Projectomschrijving

Ons afweersysteem zorgt ervoor dat ziekteverwekkers zoals virussen, bacteriën en schimmels worden opgespoord en vernietigd. Hierdoor blijven wij gezond. Bij sommige mensen keert het afweersysteem zich tegen het eigen lichaam. Het herkent de eigen lichaamsweefsels en komt in actie om de zogenaamde ‘indringers’ te vernietigen. Zo ontstaat een chronische ontsteking. Bij reumapatiënten gaat er iets mis in de communicatie tussen de afweercellen, waardoor er antistoffen worden gevormd die zich tegen lichaamseigen eiwitten richten. Kort geleden hebben we ontdekt dat deze auto-antistoffen over een unieke eigenschap beschikken omdat ze groter zijn dan andere antistoffen. Dit wordt veroorzaakt door een extra suikermolecuul dat door de afweercellen aan het antistof wordt gezet. Het is onbekend waarom dit gebeurt en of dit bijdraagt aan het ontstaan van reuma. Dit project heeft tot doel de betekenis en gevolgen van deze extra suikerstaart aan de reuma-specifieke auto-antistoffen op te helderen.

Samenvatting van de aanvraag

Background: Rheumatoid Arthritis (RA) is a chronic autoimmune disease characterized by the presence of auto-antibodies and inflammation leading to disability. Anti-Citrullinated Protein Antibodies (ACPA) are highly specific for RA and have been intimately implicated in disease pathogenesis. Recently, we made an intriguing observation by showing that ACPA display an increased size as compared to other (auto)antibodies. This size-increase is explained by the presence of additional covalently N-linked sugar chains in the antigen-binding region of ACPA. The size-shift is found in every RA-patient analysed thus far and estimated to be present on over 90% of ACPA-molecules. The biological consequences of these sugar chains on ACPA are currently unknown. Problem: Despite considerable improvements in the treatment of RA, the disease still leads to a significant loss in the patients’ quality of life, increased mortality and the treatments are associated with substantial costs for society. The problem is that current medications treat consequence by inhibiting inflammation instead of cause since the pathways underlying disease basis and progression are ill-defined. Therefore, more mechanistic insight into disease pathogenesis is of great importance. Hypothesis: We hypothesize that the abundant glycosylation of ACPA found in all ACPA-positive RA-patients is directly involved in selection of ACPA-producing B-cells. Likewise, we hypothesize that the unusual glycosylation of ACPA and/or ACPA-producing B cells contributes to disease pathogenesis, bone erosion and disease progression through the interaction with host-glycanbinding receptors such as lectins expressed on immune cells. Aim: This proposal aims to understand the reason for the abundant glycosylation of ACPA, its contribution to B-cell selection and disease-pathogenesis as well as its potential to be used as diagnostic marker for disease progression and/or development of subjects with increased RA-risk. Therefore, this project aims to delineate the role of ACPA Fab-glycosylation by: - Identification of the Siglecs/lectins that interact with glycosylated ACPA Fab-fragments - Determining the role of ACPA Fab-glycans in the activation/modulation of osteoclasts and other immune cells - Determining at which time point in disease development ACPA-producing B-cells have introduced an N-linked glycosylation-site in the Fab-region - Determining if- and how Fab-glycans affect the threshold for B-cell activation - Determining the role of ACPA-Fab-glycosylation in binding and avidity to citrullinated antigens - Determining the diagnostic/prognostic properties of ACPA-Fab-glycosylation Outlook: As the hyperglycosylation of ACPA is the result of a post-translational modification in its’ variable domain and is independently occurring in every active RA-patient analysed thus far, it is likely that it provides a survival advantage of ACPA-producing B cells and/or that it mediates the RA-phenotype. Therefore, the proposed studies are expected to provide pivotal insight into the emergence/propagation of the auto-reactive B-cell population hallmarking RA as well as into the contribution of ACPA hyperglycosylation to RA-pathogenesis. Thereby, they might identify new targets for specific treatments aiming to counteract the most relevant auto-antibody response for RA as well as diagnostic tools predictive for RA-development in at risk populations.
