Działanie neuroimmunomodulacyjne wysokotoksycznego związku fosforoorganicznego na rozwój infekcji Trichinella spiralis

The highly toxic organophosphorus compound (isopropylmethylphosphonofluoridate — IMPF) belonging to the group of the so called toxic of warfare agents can impair immune effector mechanisms determining the development of parasitic infection. Preliminary studies have demonstrated that IMPF delays elimination of adults Trichinella spiralis forms from the intestine of C57B1/6 mice and B6C3F1 hybrids. Besides, the studied compound modifies the proliferative activity of T-cells in the above mentioned mice and reduces the production of anti-SRBC antibodies in C57B1/6 strain. The mechanisms are discussed of the organophosphorus compound effect on neuroimmunological processes connected with antiparasitic immunity, paying attention also to the function of these processes by the parasitic infection itself, in host-parasite relationship. The probability is also considered of increased sensitivity to Leishmania infection in humans poisoned with IMPF and/or other organophosphorus compounds.
