An account is given of the experimental in vivo transfer of PPD-specific delayed hypersensitivity with a very small number of autologous lymphocytes pre-sensitised with PPD-specific transfer factor (TF). Transfer was assessed in 17 volunteers both in vivo by means of the Mantoux skin reaction, and in vitro by means of the leukocyte migration inhibition test, the lymphocyte locomotion test, and the leukocyte adherence inhibition test. Positivization of the tests suggests that TF triggers a reaction which expands the effect of hypersensitivity.

UI MeSH Term Description Entries
D007957 Leukocyte Adherence Inhibition Test Test for cell-mediated antitumor immunity and related serum blocking factors based on the finding that leukocytes from cancer patients, but not from controls, when mixed in vitro with antigenic extracts of tumors of the same histological type, undergo a diminution in their normal adherence to glass surfaces. Sera from tumor-bearing patients block the LAI reaction of their own leukocytes or those of other patients with the same type of tumor. LAI Test,LAI Tests,Test, LAI,Tests, LAI
D008214 Lymphocytes White blood cells formed in the body's lymphoid tissue. The nucleus is round or ovoid with coarse, irregularly clumped chromatin while the cytoplasm is typically pale blue with azurophilic (if any) granules. Most lymphocytes can be classified as either T or B (with subpopulations of each), or NATURAL KILLER CELLS. Lymphoid Cells,Cell, Lymphoid,Cells, Lymphoid,Lymphocyte,Lymphoid Cell

D012882 Skin Tests Epicutaneous or intradermal application of a sensitizer for demonstration of either delayed or immediate hypersensitivity. Used in diagnosis of hypersensitivity or as a test for cellular immunity. Skin Test,Test, Skin,Tests, Skin

D014373 Tuberculin A protein extracted from boiled culture of tubercle bacilli (MYCOBACTERIUM TUBERCULOSIS). It is used in the tuberculin skin test (TUBERCULIN TEST) for the diagnosis of tuberculosis infection in asymptomatic persons.
