The immunopathology of cardiac xenograft rejection in the guinea pig-to-rat model.


The mechanisms underlying rejection by rats of vascularized guinea pig xenografts have been controversial. The aim of this study was to define, using sequential immunopathologic analysis, the contributions of xenoreactive antibody, complement, and effector cells to the rejection of guinea pig cardiac xenografts by Lewis rats. In untreated recipients… (More)
