Organ Transplantation & Graft Rejections

Organ Rejection

The body's immune structure usually protects you from materials that may be harmful, such as Origins, poisons, and occasionally, cancer cells. These harmful materials have proteins called antigens covering their shells. As soon as antigens arrive the body, the immune system recognizes that are not since that person's body and that they are "external," and attacks them. A person receives an organ from someone else during transplant surgery, that person's immune system knows that it is distant. This stands since the person's immune system discovers that the antigens on the cells of the organ are different or not "coordinated." Incompatible organs, or organs that are not matched closely enough, can activate a blood transfusion response or Organ rejection.
