Abstract
ACQUIKED immunological tolerance wanes gradually with time after antigen injections are stopped1. In some experiments the termination of the tolerant state has been hastened by whole-body X-radiation2–5. Weigle has recently found that tolerance to bovine serum albumin (BSA) induced by giving very large quantities of antigen to new-born rabbits is not terminated by whole-body X-radiation, nor by passive anti-BSA nor by both these agents together6. Weigle has also reported that termination of tolerance to BSA in rabbits following the injection of a serologically related antigen is not thymus dependent7. We have recently reported that thymectomy prolongs the tolerance to bovine γ-globulin (BGG) induced in the adult mouse8. The purpose of these experiments was to investigate the effect of whole-body X-radiation on the termination of tolerance in thymectomized and sham-operated mice.
