[Changes in allogeneic immune response of swine in the course of a liver allograft].

Pig liver allografts showed a typical rejection crisis. The degree of rejection depended on the SLA-typing. Despite SLA-incompatibility pig liver allografts can be tolerated. Short-term survivors showed an immunological hyporeactivity. Long-term survivors reconstituted their cellular immune-reactions and developed an antibody which appeared to function as an antigen-antibody-complex or an anti-Ia-antibody.
