We have developed a model of aortic allograft vasculopathy (AV) that uses mouse strains that are fully disparate at Class I, Class II and minor histocompatibility antigens. Acute rejection is ablated with therapeutic doses of the calcineurin inhibitor Cyclosporine A (CyA). In this way we successfully mimic human disease. Using this model we have(More)
Using a clinically relevant, fully disparate, allogeneic aortic transplant mouse model of allograft vasculopathy, we have demonstrated that neointimal proliferation is dependent on CD8(+) T cell effector pathways in the presence of therapeutic doses of calcineurin inhibitor (CNI) immunosuppression. CD4(+) T cell pathways are ablated by CNI(More)
The respective roles of the endothelium and the media as allo-immune targets in the generation of allograft vasculopathy (AV) have yet to be clearly defined. Although endothelial damage has been implicated in the progression of AV, evidence from mechanical vascular injury models suggests that medial injury may play a more dominant role. The overall(More)
Mutations in genes that code for components of the Norrin-FZD4 ligand-receptor complex cause the inherited childhood blinding disorder familial exudative vitreoretinopathy (FEVR). Statistical evidence from studies of patients at risk for the acquired disease retinopathy of prematurity (ROP) suggest that rare polymorphisms in these same genes increase the(More)
