| abstractText | We have been successful in our efforts to develop a long lived noncytolytic murine IL-10/Fc fusion protein. In the nonobese diabetic mouse (NOD) model, administration of IL-10/Fc from 5 to 25 wk of age completely prevented the occurrence of diabetes. Moreover, these mice remained disease-free long after cessation of IL-10/Fc therapy. Immunohistochemistry studies show that IL-10/Fc treatment inhibits expression of TNF-alpha, proinflammatory cytokine, as well as Th1-type cytokines, IL-2 and IFN-gamma, but promotes expression of IL-4 and IL-10, Th2-type cytokines, by islet-infiltrating leukocytes. In an adoptive transfer model of diabetes in NOD mice, we found that: 1) IL-10/Fc treated hosts bear leukocytes that block expression of diabetes and 2) these leukocytes persisted even 8 wk after cessation of IL-10/Fc treatment. The potent antidiabetogenic effects provided by IL-10/Fc in the NOD model, together with its apparent lack of systemic toxicity, are notable. |
