B Lymphocytes Impede Tregs To Erode Islet Tolerance In Type 1 Diabetes, Daniel J Moore

Faculty, Staff and Students Publications

B lymphocytes are thought to drive β-cell destruction in type 1 diabetes (T1D) by activating anti-islet T cells. However, the observation that autoreactive T-cell activation and disease progression can occur without B cells challenges this view. Still, preclinical and clinical studies have shown that B-cell depletion alleviates β-cell destruction, suggesting a critical role for B cells in T1D. Our findings propose an alternative function for B cells, impairing regulatory T cells (Tregs) that would otherwise protect islets. In the NOD islet transplant model, we show that B-cell absence enables transplant tolerance, allowing Tregs to become responsive to immune therapy and …
