THE NON-SPECIFIC ACCEPTANCE OF SKIN TRANSPLANTS BY RADIATION CHIMERAS

OSTI ID:4839221
ABS>The immunological status of lethally irradiated mice protected against the acute effects of radiation by the transfusion of rat or allelogenic, parental, or isogenic bone marrow was studied using the reaction against skin grafts as the indicator system. The data indicated that the radiation chimeras were immunologically unresponsive animals and were, therefore, able temporarily to accept skin grafts from donors foreign to both the irradiated host and the marrow donor. It was concluded that the ultimate rejection of the skin grafts was the result of the recovery of the host's immune response rather than the result of any contribution of donor marrow cells to the immune system. If the animal survives, a specific tolerance towards the bone marrow donor's skin may develop. A possible alternative hypothesis to explain the persistence of the foreign skin grafts despite deaths from secondary disease is discussed. (auth)
