Research Abstract |
Malaria is one of the most serious infectious diseases worldwide. Therefore, there were many reports suggested the importance of nutritional status to maintain the immunity against pathogens. In particular, zinc is known to play a critical role in responding to infections including malaria. We have examined the relationship between zinc deficiency and murine malaria infection. The objective of this study is to explore the effect of zinc deficiency to the immunity against malaria. Mice fed with zinc deficient diet were infected with murine malaria parasites and the immunological parameters were sequentially analyzed. The results of this study indicated the zinc deficiency might affect the immune responses to malaria. The following is suggested; in early phase of infection, both innate immunity and phagocytic activities of macrophages can be maintained. However, acquired immune system might fail to induce the production of malaria specific antibodies to eliminate the parasites.
