| Research Abstract |
Regulatory B cells that produce IL-10 are an important role for negative immune response. The frequency of regulatory B cell in PBMC from 28 systemic sclerosis patients and 24 healthy controls were examined. The frequency of regulatory B cell in PBMC was decreased in systemic sclerosis patients compared to healthy controls. Next, the role of regulatory B cell in the cytokine induced fibrosis models was examined using lack of regulatory B cell mice (CD19 deficient mice). There was no significant difference between wild type mice and CD19 deficient mice.These results suggest that decreased regulatory B cell may contribute to pathogenesis of systemic sclerosis, although regulatory B cell does not affect the development of fibrosis.
