| Outline of Final Research Achievements |
Although IgG molecule has single N-glycosylation site in the Fc region and various glycosylation patterns have been reported, their functions have been unclear. Then, we have established ST6Gal1-deficient mice lines lacking sialic acids specifically in activated B cells, and have tried to induce experimental arthritis in them. Consequently, it has been demonstrated that sialylation-deficient mice exhibit exacerbation of RA features compared to wild type mice. On the other hand, administration of sialylated auto-antibody IgG into RA-model mice resulted in rather suppression of clinical features of RA.
