2. Organ transplant
When an organ is replaced with an organ from another person. The organ can sometimes be seen as a “foreign invader” from the immune system

3. Cell surface proteins
Transplanted organs have different or foreign antigens on their cells. This is similar to how the immune system sees a virus or bacteria cell

4. Different cell proteins
Donor cell proteins
Receiver’s cell proteins
These cells are not a match for an organ transplant

5. Organ transplant rejection
Organ transplant will reject if proteins do not match
Immune system will trigger white blood cells to attack the transplanted organ

6. Immunosuppressants Immuno - immune system suppressants - lower
Immunosuppressants are drugs that
lower the immune systems response to
transplanted organs.
