Mechanisms of graft acceptance: evidence that plasminogen activator controls donor-reactive delayed-type hypersensitivity responses in cardiac allograft acceptor mice.


We have used delayed-type hypersensitivity (DTH) responses to probe the mechanisms of drug-induced cardiac allograft acceptance in mice. DBA/2-->C57BL/6 cardiac allograft recipients treated transiently with gallium nitrate accept their grafts for >90 days and fail to display DBA/2-reactive DTH responses. These DTH responses are restored when anti-TGF-beta… (More)
