Write answer in between .Q:Several weeks following a kidney transplantation, a 50-year-old Caucasian female presents for evaluation of the transplanted organ. Biopsy shows inflammation involving the endothelial cells of the kidney vasculature and the presence of mononuclear cells in the interstitium. Which cells are most likely responsible for this presentation?? A: Donor T-cells, B: Recipient T-cells, C: Preformed recipient antibodies, D: Donor antibodies, E: Deposition of antibody immune complexes,  <response>: This question is asking about the likely cause of inflammation and mononuclear cell infiltration in a transplanted kidney several weeks after transplantation. The choices present different immune mechanisms that could potentially cause rejection.A kidney transplant recipient is given immunosuppressive drugs to prevent rejection by the recipients immune system. However, rejection can still occur, especially in the weeks and months after transplantation as the recipients immune system recovers. The inflammation of endothelial cells and presence of mononuclear cells suggests this is rejection mediated by the recipients T cells choice B. Donor T cells choice A are depleted during transplant preparation. Preformed antibodies choice C typically cause hyperacute rejection within hours to days of transplant. Donor antibodies choice D and immune complexes choice E are less likely causes of rejection weeks after transplant.B: Recipient T-cells
