Immunologic mechanisms of the tube leukocyte adherence inhibition assay in adjuvant-induced disease in rats. 1980

H Tannenbaum, and K Poskitt

In the leukocyte adherence inhibition assay (LAI), splenic leukocytes from normal and adjuvant-induced disease (AID) rats were incubated with synovial extracts obtained from AID and normal joints. The proportion of leukocytes nonadherent to the surface of a glass tube in the presence of either AID or normal synovial extract was compared and this difference was expressed as a nonadherent index (NAI). The AID rats have significantly higher NAI scores (29 +r4) than normal rats (0 +r5). Preincubation of splenic leukocytes from normal rats with sera from AID animals caused these normal cells to respond with positive NAI scores (25 +r6). The IgG fraction from AID sera was shown to be an important component in arming these normal splenic leukocytes and a dose response curve was noted. Preincubation of AID splenic leukocytes with antiserum to rat IgG abrogated the positive NAI scores, whereas antiserum to rat IgM had no effect on the NAI values. The reactive cell in the LAI assay was a mononuclear cell whose activity was removed by adherence to plastic petri dishes. We suggest that IgG plays an important role in the LAI assay and might bind to plastic adherent mononuclear cells (monocytes?), through their Fc receptor to allow these cells to react with AID synovial extracts.

D007106	Immune Sera	Serum that contains antibodies. It is obtained from an animal that has been immunized either by ANTIGEN injection or infection with microorganisms containing the antigen.	Antisera,Immune Serums,Sera, Immune,Serums, Immune
D007136	Immunoglobulins	Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.

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
