New clues discovered to lung transplant rejection

A lung transplant often remains the only option for many patients with end-stage lung disease, a condition that can be brought on by emphysema, pulmonary fibrosis, cystic fibrosis and other lung disorders. However, the risk ...

Engineered T cells promote long-term organ transplant acceptance

Organ transplant rejection is a major problem in transplantation medicine. Suppressing the immune system to prevent organ rejection, however, opens the door to life-threatening infections. Researchers at the University of ...

New insights into what drives organ transplant rejection

When it comes to transplant rejection, some organs are far trickier than others. Some transplantable organs, such as the liver, are readily accepted by the recipient's immune system, rarely triggering an immune response and ...

Transplant rejection

Transplant rejection occurs when a transplanted organ or tissue is not accepted by the body of the transplant recipient. This is explained by the concept that the immune system of the recipient attacks the transplanted organ or tissue. This is expected to happen, because the immune system's purpose is to distinguish foreign material within the body and attempt to destroy it, just as it attempts to destroy infecting organisms such as bacteria and viruses.
