True or false: Adaptive immunity occurs rapidly, is antigen specific and has cellular memory
False. Slow (1-2 weeks), antigen specific and has cellular memory
T-lymphocytes are produced in the _____ ________ and mature in the ________
Bone marrow. Thymus.
What is the complement system responsible for?
Opsonization, Inflammation, Lysis
Sensitized patients have a panel of reactive antibodies (PRA) > ___ %
20%
What is the difference between preformed and de novo donor specific antibodies (DSA) forming?
Preformed: identified before transplant and increased chance for early rejection and graft loss
de novo: developed after transplant and associated with late and chronic rejection
Why is immunosuppression necessary for solid
organ transplantation?
1. To protect the recipient from donor immunologic cells
that came with the organ
2. To protect the allograft (donor organ) from the
recipient’s immune system
3. Precautionary until the recipient becomes tolerant to
the allograft
4. Immunosuppression is voodoo medicine, we really do
