- Antigen presentation in celiac diseaseShuo Wang Qiao
Centre for Immune Regulation, Institute of Immunology, Rikshospitalet University Hospital and University of Oslo, Norway
Curr Opin Immunol 21:111-7. 2009..In comparison, DQ8 exhibits different binding characteristics, which may explain the lesser risk for disease in association with this molecule...
- A quantitative analysis of transglutaminase 2-mediated deamidation of gluten peptides: implications for the T-cell response in celiac diseaseSiri Dørum
Centre for Immune Regulation, Institute of Immunology, University of Oslo, and Rikshospitalet University Hospital, N 0027 Oslo, Norway
J Proteome Res 8:1748-55. 2009..Thus, the rate of deamidation by TG2 appears to be a factor of importance for the T-cell response to gluten in celiac disease...

- High abundance of plasma cells secreting transglutaminase 2-specific IgA autoantibodies with limited somatic hypermutation in celiac disease intestinal lesionsRoberto Di Niro
Centre for Immune Regulation and Department of Immunology, University of Oslo and Oslo University Hospital Rikshospitalet, Oslo, Norway
Nat Med 18:441-5. 2012..This could result in preferential recruitment of plasma cells from naive IgD- and IgM-expressing B cells, thus possibly explaining why the antibody response to TG2 bears signs of a primary immune response despite the disease chronicity...
