The replacement of diseased cells with artificial implants
Which of the following is an example of an autograft?
Kidney transplant between siblings
Skin graft from one area of the body to another in the same person
Heart transplant between unrelated individuals
Transplantation of pig heart valves into humans
What type of transplant involves tissues or organs from a genetically identical donor?
Allograft
Xenograft
Isograft
Autograft
Which type of transplantation involves crossing species barriers?

Xenograft
Autograft
Which of the following is NOT a factor affecting transplantation success?

Cross-matching results
What is the primary purpose of cross-matching in transplantation?
To measure the size of the graft

To prevent hyperacute rejection
To identify viral infections in the donor
What is panel reactive antibody (PRA) testing used for?
Evaluating donor organ function
Detecting recipient antibodies against donor antigens
Determining blood type
Measuring organ viability post-transplant
What type of transplant involves unrelated individuals of the same species?
Allograft
Isograft

Xenograft
Which of the following organs is most affected by MHC mismatch?
Heart
Kidney
Liver
Cornea
Which test directly measures recipient serum reactivity with donor lymphocytes?
HLA typing
Cross-matching
PRA testing
Blood group typing
Antigen-presenting cells (APCs) play no role in transplant rejection.
True
False
Direct allorecognition involves recipient T-cells recognizing donor MHC directly.
True
False
Hyperacute rejection occurs within hours of transplantation.
True
False
Acute rejection is primarily mediated by B-cells.
True
False
Chronic rejection involves both immune and non-immune mechanisms.
True
False
Indirect allorecognition involves the processing and presentation of donor antigens by recipient APCs.
True
False
Graft-versus-host disease (GVHD) occurs only in solid organ transplants.
True
False
HLA mismatches are the primary cause of acute rejection.
True
False
GVHD is more common in bone marrow and stem cell transplants.
True
False
Preventing hyperacute rejection requires careful matching of ABO blood groups.
True
False
Abigail is studying the cellular mechanisms involved in acute graft rejection after her friend Benjamin received a kidney transplant. Can you describe the processes that occur at the cellular level during this rejection?
What mechanisms do antibodies employ to contribute to the process of chronic rejection in transplanted organs?
What is graft-versus-host disease (GVHD)?
List two strategies to prevent GVHD.
Why is immunosuppression essential in transplantation?
What role do calcineurin inhibitors like tacrolimus play in organ transplantation?
Lily has been on long-term immunosuppressive therapy for her autoimmune condition. What are the risks associated with this treatment?
What is the significance of donor HLA typing?
