A proportion of both donor and host DC may cross-present. Although there has been many studies that have investigated the role of donor versus host DC (i.e., direct vs. indirect pathway), what role cross-presenting DC play in allograft rejection has not been determined. We recently identified an agent, cytochrome c (cytc), that selectively depletes cross-presenting DC in vivo. By administering cytc we were able to study the impact of cross-presenting DC on rejection of islets grafted into fully mismatched mice. We found that cytc protected about half of the islet allografts from rejection. Our results indicate that cross-presenting DC can make potent contributions to the immune response to islet allografts, and contend that agents such as cytc that selectively target DC heralds a novel method of immunosuppression.", pages = "467-474", url = "http://www.ingentaconnect.com/content/cog/ct/2011/00000020/00000003/art00010", doi = "doi:10.3727/096368910X528094", keyword = "Dendritic cell, Cross-presentation, Immunosuppression, Allograft, Islet" }
