Outline of Final Research Achievements |
To clarify the role of M3R immune response in the generation of Sjogren’s syndrome (SS), we established M3R induced sialadenitis (MIS) mouse model and examined whether M3R reactive T cells trigger the autoimmune sialadenitis or not. In the present study, we obtained evidence that M3R reactive Th1 and Th17 cells were associated with the generation of MIS, the major T cell epitopes of M3R were N1 and the first extra-cellular domain, and one of analogue ligand peptide (APL) coding N1 region could inhibit the induction of sialadenitis significantly. These observations should shed light on the antigen-specific therapy in SS near future.
