| Outline of Final Research Achievements |
The purpose of this study was to analyze the role of a proliferation-inducing ligand (APRIL) in patients with IgG4-related disease (IgG4-RD). APRIL was expressed in kidney inflammation, and corticosteroid treatment decreased the expression of APRIL in the renal tissue of patients with IgG4-related kidney disease. We found that the main APRIL-producing cells were M2 macrophages. We also confirmed the expression of APRIL in the inflammatory lesion of Lat Y136F knock-in mice. Treatment with APRIL-blocking antibody suppressed the development of the kidney lesions in these mice. Furthermore, we confirmed the high expression level of BAFF in the lesions of patients with IgG4-RD and Lat Y136F knock-in mice. These data indicate that APRIL and BAFF are related to the pathogenesis of IgG4-RD.
