Effect of levamisole on leukocyte adherence inhibition. 1981

T Appelboom, and J P Famaey, and R Görtz, and J Wybran

The leukocyte adherence inhibition test can serve as an in vitro model to investigate the cellular cooperation between T cells, monocytes and polymorphonuclear cells (PMN) but also the mechanism of cell adherence. Therefore, the effect of levamisole on the production of PMN activating factors by mononuclear cells and on cell adherence was studied with leukocytes from polyarthritic patients. Levamisole at concentrations ranging from 10(-9) M to 10(-4) M did not seem to affect the production of activating factors. These results differentiate levamisole from anti-inflammatory drugs which are potent inhibitors. On the other hand, levamisole increased markedly the adherence of leucocytes, mainly mononuclear cells, obtained from polyarthritic patients, or normal cells preincubated in a polyarthritic serum. This could be related to a direct effect of levamisole on the leukocyte membrane.

UI MeSH Term Description Entries
D007700 Kinetics The rate dynamics in chemical or physical systems.
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).

D007978 Levamisole An antihelminthic drug that has been tried experimentally in rheumatic disorders where it apparently restores the immune response by increasing macrophage chemotaxis and T-lymphocyte function. Paradoxically, this immune enhancement appears to be beneficial in rheumatoid arthritis where dermatitis, leukopenia, and thrombocytopenia, and nausea and vomiting have been reported as side effects.
