Pig peripheral blood mononuclear cells are directly associated with the thrombotic microangiopathy that complicates the induction of chimerism in pig-to-baboon xenotransplantation.

abstract：BACKGROUND:The induced antibodies against Galalpha1,3Gal (Gal) and non-Gal epitopes may contribute to delayed xenograft rejection (DXR). We asked whether blockade of the CD40/CD154 and CD28/B7 co-stimulatory pathways modulates the baboon elicited antibody response to pig Gal and non-Gal antigens. METHODS:Eighteen babo...
