| pubmed-article:17112895 | pubmed:abstractText | There is a need to achieve donor-specific tolerance in clinical organ transplantation, where potential benefits remain overshadowed by chronic rejection and the side-effects of long-term immunosuppressive therapy. It is known that the mature immune system in mice can be reprogrammed to accept a foreign graft as if it was "self". The AdCTLA4Ig-mediated gene transfer (SC) + cyclophosphamide (CP) treatment alone prolongs allograft survival but does not induce tolerance. However, in our study, the AdCTLA4Ig-mediated gene transfer combined with SC + CP treatment yielded significantly prolonged mean survival times (149.7 +/- 18.0 days), while those in the untreated or AdLacZ treated mice were rejected in normal fashion (5.3 +/- 0.5 and 5.2 +/- 0.4 days, respectively), and survival in the AdCTLA4Ig or SC + CP treated groups were 45.7 +/- 9.6 or 50.2 +/- 5.3 days, respectively. In conclusion, a protocol of AdCTLA4Ig + SC + CP improved the survival of DA-->LEW cardiac allografts. | lld:pubmed |
