[EFFECT OF 4-METHYLPYRAZOLE ON IMMUNE RESPONSE, FUNCTION OF Th1 AND Th2 LYMPHOCYTES, AND CYTOKINE CONCENTRATION IN
Abstract:
It was established in experiments on noninbred albino rats that the acute intoxication with methanol (1.0 LD50) decreased cellular and humoral immune responses, Th2-lymphocyte activity (to a greater extent as compared to the function of Th1 cells), reduced the blood concentration of immunoregulatory (IFN-g, IL-2, IL-4) and proinflammatory (TNF, IL-1b, IL-6) cytokines on the average by 36.5% (p < 0.05), and did not affect the content of anti-inflammatory cytokines (IL-10, IL-13). Methanol antidote 4-methylpyrazole (non-competitive inhibitor of alcohol dehydrogenase) administered upon acute intoxication with methanol at a dose of 1.0 DL50 partially reduces the intoxication-induced suppression of humoral and cellular immune response, activity of T-helper cells, and production of IL-4 and restores blood levels of TNF, IL-1b, IFN-γ, IL-4, IL-2, IL-6 to the control values.
