Effect of HI-6 on cytokines production after immunity stimulation by keyhole limpet hemocyanin in a mouse model.

OBJECTIVES: HI-6 or asoxime in some sources is an antidotum for nerve agents. In recent experiments, implication of HI-6 in immunity response was proved; however, the issue was not studied in details. In this experiment, role of cytokines in HI-6 impact on immunity was searched. DESIG N: BALB/c mice were exposed to saline, HI-6 in a dose 1-100 mg/kg and/or 1 keyhole limpet hemocyanin (KLH) 1 mg/kg. Mice were sacrificed 21 days after experiment beginning and interleukins (IL) 1, 2, 4, 6 were determined by Enzyme Linked Immunosorbent Assay (ELISA).

RESULTS: The animals had no pathological manifestation. From the tested cytokines, no significant alteration was found for the IL-1, IL-4 and IL-6. IL-2 was significantly increased in a dose response manner.

CONCLUSIONS: The experimental data well correlates with the previous work where HI-6 caused increase of antibodies production. HI-6 is suitable to be used as an adjuvant whenever immunity should be pharmacologically altered.
