Summary

Many patients suffer from devastating injuries to vascularized composite tissues. Vascularized composite tissues are blocs of functional tissue that can contain multiple tissue types such as bone, muscle, nerves, blood vessels, tendons, ligaments, and others. Examples of patients with severe vascularized composite tissue defects include limb amputees, patients with third-degree burns to the face or extremities, soldiers with improvised-explosive-device blast injuries to the face, and others. These patients cannot be helped satisfactorily with conventional reconstructive surgery; however, recently vascularized composite allotransplantation (VCA) such as transplantation of faces and limbs became available to this patients. Unfortunately, at this juncture, patients who receive VCA must submit to life-long regime of immunosuppressant drugs with serious side effects such as infection, renal toxicity and cancer. Immune tolerance is the absence of a destructive immune response from the recipient's body to the transplant, while otherwise maintaining sufficient immune function to fight infections and other threats. Transplant recipients with immune tolerance do not need to take immunosuppression drugs. The investigators believe that they can achieve immune tolerance in recipients of face and limb transplants.
