Comparison of a leucocyte adherence test with the leucocyte migration inhibition test and skin reactivity to PPD. 1978

A W Bullen, and M S Losowsky

Using PPD as antigen, a leucocyte adherence test was compared with the leucocyte migration inhibition test and with the results of skin testing in healthy subjects. In the presence of antigen, leucocyte adherence was significantly greater in skin test-positive subjects than in skin test-negative subjects who had not previously had BCG vaccination. When the test was performed in heterologous serum, skin test-negative subjects who had had previous BCG vaccination showed significantly greater leucocyte adherence in the presence of antigen than skin test-negative subjects who had not had BCG vaccination; this difference was not present in autologous serum and its abolition was attributed to a serum blocking effect. The leucocyte adherence test correlated with the results of the leucocyte migration inhibition test in heterologous serum, and also with the results of skin testing interpreted in the light of previous vaccination history. The finding of increased rather than decreased adherence in the presence of antigen, although previously reported, is unusual.

D007111	Immunity, Cellular	Manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role.

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
D007962	Leukocytes	White blood cells. These include granular leukocytes (BASOPHILS; EOSINOPHILS; and NEUTROPHILS) as well as non-granular leukocytes (LYMPHOCYTES and MONOCYTES).

D002464	Cell Migration Inhibition	Phenomenon of cell-mediated immunity measured by in vitro inhibition of the migration or phagocytosis of antigen-stimulated LEUKOCYTES or MACROPHAGES. Specific CELL MIGRATION ASSAYS have been developed to estimate levels of migration inhibitory factors, immune reactivity against tumor-associated antigens, and immunosuppressive effects of infectious microorganisms.

D001500	BCG Vaccine	An active immunizing agent and a viable avirulent attenuated strain of MYCOBACTERIUM BOVIS, which confers immunity to mycobacterial infections. It is used also in immunotherapy of neoplasms due to its stimulation of antibodies and non-specific immunity.
