Studies on the Transfer of Human Delayed-Type Hypersensitivity

[摘要] Two fractions from tuberculin hypersensitive human white blood cells have been found capable of transferring tuberculin delayed hypersensitivity. One of these (C′-5) is a polynucleotide containing adenine, guanine and cytosine, but no uracil. The second transfer factor is contained in a larger molecular weight (A′) fraction found to have γG-globulin and other globulin and probably α1 lipoprotein as well as ribose indicating RNA.A fraction containing macroglobulin was unable to transfer delayed hypersensitivity.
