| Research Abstract |
(1) Immunological tolerance was achieved by intravenous injection of CTLA41g (100mug/head) for 7days in rat small bowel allografts. Long survival (>100days) of allografed small bowel was achieved in rat system. Increased serum levels of IL-4 and IL-10 were defected in tolerant rats, indicating that the Th2 type anti-allogeneic immune response favors the survival of allografted tissue.
(2) Immunological tolerance was also achieved by intravenous injection of CTLA4Ig in rat kidney allografts. However, injection of allogeneic splenic dendritic cells or CTLA4Ig-treated dendritic cells failed to induce tolerance or long survival of allografted Kidney.
(3) We generated adenovirus vectors containig CTLA4Ig, which can be used for the in vivo and in vitro production of CTLA4Ig.
