Abstract
Summary: The cells responsible for delayed hypersensitivity reactivity in the mouse act in a radioresistant fashion only if such irradiated cells are injected directly into the site of antigen challenge. Intravenous transfer of irradiated, primed spleen cells does not achieve a transfer of sensitivity to show delayed type hypersensitivity reactions. Transfer of sensitivity by the intravenous route can be effected by injection of non-irradiated spleen cells from primed mice.
