摘要

One Lyt-2+ clone and fourteen T-helper clones (Lyt-1+ L3T4+ Lyt-2-) were isolated from Mycobacterium lepraemurium-infected BALB/c and C57BL/6 mice. All the clones were tested for their ability to transfer delayed-type hypersensitivity adoptively, and six clones were tested for their ability to transfer resistance. It was found that four L3T4+ clones that transferred delayed-type hypersensitivity responses locally and one L3T4+ clone that did not had no effect on resistance. The Lyt-2+ clone transferred increased resistance locally (77% reduction in the numbers of organisms recovered from the infection site) but did not transfer delayed footpad responses.
