| Outline of Final Research Achievements |
Murine sclerodermatous chronic graft-versus-host disease (Scl-cGVHD) is a model for human Scl-cGVHD and systemic sclerosis (SSc). Syk is a protein tyrosine kinase that has an important role in transmitting signals from a variety of cell surface receptors.This study aims to investigate the effect of a Syk inhibitor, R788, on Scl-cGVHD and role of Syk in patients with SSc. Allogeneic BMT increased Syk phosphorylation in T, B, and CD11b+ cells. Early administration of Syk inhibitor attenuated severity and fibrosis of Scl-cGVHD. Syk inhibitor also reduced skin mRNA expressions of IL-13, IL-17A, and TGF-β1. However,Syk phosphorylation in B cell of SSc patients was not increased compared with that of normal control. The current studies suggested that Syk inhibitor is a potential candidate for use in treating patients with Scl-cGVHD and SSc.
