Understanding and targeting the derailment of immunopathology of systemic autoimmune diseases is the aim of the van Roon group. These diseases mainly include primary Sjogren’s syndrome (pSS), systemic lupus erythematosus (SLE) and systemic sclerosis (SSc). By applying state-of-the-art technological platforms the goal is to identify key molecular mechanisms that are trivial to immunopathological processes that underly increased morbidity and mortality in these diseases. The aim is to apply this knowledge to other immune mediated inflammatory diseases (IMIDs). In depth delineation of key players that organize autoimmune responses such as effector T cells (CXCR5 Tfh cells, CCR9 pathogenic Th cells), B cells and innate cells (pDCs, cDCs, monocytes aims to unravel the specific contributions to the concerted immune reactions. Development of novel tools to capture the inflammatory responses is another major effort to understand immunopathology (eg. Epigenetic cell counting in tissue, Tissue Secretome analysis, Dry blood spot analysis). 

Development of additive/synergistic anti-inflammatory approaches is a recurring  core strategy that is aimed for. One example of successful drug combinations/therapeutic strategies that were developed by the van Roon group are synerkines (eg IL4-10 fusion protein) that potently halt Th1/Th17-driven immunopathology and pain in (osteo)arthritic conditions. Another example is strong additive inhibition of arthritis and arthritis-induced immunopathology by simulataneous TSLP and IL-7-driven immune activation. The most recent is successful disease inhibition by targeting additive/synergistic inflammatory pathways by leflunomide/hydroxychloroquine combination therapy in Sjogren’s disease.
