title: [Immunologic tolerance after experimental liver transplantation].
abstract: Allografts in the rat liver are rejected less vigorously than other primarily vascularized allografts; they show a better survival rate and induce donor-specific unresponsiveness or tolerance in some donor-recipient combinations. This overview focuses on the immunologic mechanisms of this privileged status of liver allografts. A variety of possible mechanisms, such as generation of suppressor T-cells, humoral factors and microchimerism, has been related to the observed hyporeactivity. A further analysis of these phenomena may enhance the development of clinical organ transplantation protocols that allow for establishment of donor-specific unresponsiveness without the need for life-long immunosuppression.
