Term
Direct Pathway of Rejection |
|
Definition
Foreign MHC presents its own antigen which is foreign to the recipient, and this activates the recipient's T cells. The cause of Acute Rejection. |
|
|
Term
Indirect Pathway of Rejection |
|
Definition
Recipient immune cells phagocytose cells from graft and present foreign MHC molecules to their T cells. This is the cause of Chronic Rejection. |
|
|
Term
Autologous Stem Cell Transplant |
|
Definition
donor is self or identical twin. take stem cells from the patient, irradiate the patient, give them back their stem cells. the cells are not rejected. |
|
|
Term
Allogenic Stem Cell Transplant |
|
Definition
donor is another person. they will be rejected unless the host immune system is repressed and T cells are eliminated from the donor. |
|
|
Term
First set allograft rejection |
|
Definition
the first time a donor gives cells to a recipient, they are rejected within 2 weeks, and now the host's T cells are primed against this particular donor |
|
|
Term
Second set allograft rejection |
|
Definition
cells from a donor are given a second time, and now a secondary immune response is mounted against the donated cells because memory T cells exist against it. it is rejected within 1 week. |
|
|
Term
|
Definition
transplant is destroyed by pre-existing antibodies, a secondary response. This is a second set rejection. No CMI response. |
|
|
Term
|
Definition
Donor APCs migrate to host lymph nodes and present their antigens to the host's T cells, which starts an immune response. This is direct pathway of rejection. Most Common. |
|
|
Term
|
Definition
months to years after transplant, indirect pathway of rejection. |
|
|
Term
|
Definition
Donor T cells attack the host's antigens. Avoid by removing T cells from graft before transplanting. |
