Outline of Final Research Achievements

The levels of FVIII inhibitors began to decline within 6 weeks after subcutaneous BOECs implantation and finally, the inhibitor levels had declined less than 5 BUs after the multiple implantations of transduced BOECs.The significant numbers of CD4+ CD25+ Foxp3 regulatory T cells were detected in spleen and draining lymph nodes of these partially tolerized mice and these suppressive effects against cFVIII could be adoptively transferred to naïve hemophilia recipient mice. We show that FVIII releasing subcutaneous depots play an important role of immunomodulatory effects that have a potential to reduce the levels of anti-FVIII inhibitor titers.
