My research interest is how external influences can influence the immune system in such a way that unwanted immune responses, such as, for example, auto-immune diseases can arise. Molecular analysis of immunoglobulin genes provides insight into which B cells are stimulated during such immune responses. This may explain why anti-B cell therapy is very effective in various autoimmune diseases such as RA, Sjögren syndrome, ANCA associated vascultis and type 1 diabetes. During secondary humoral immune responses there might be an abnormal selection of autoreactive B cells due to an altered glycosylation pattern.
