Analysis of acquired immunity system in insects

点击翻译按钮获取中文摘要

Insects possess an innate immunity system that is characterized as immune reactions with non-specific factors. Although insects are known to lack an acquired immunity with immunological memory, it is still controversy whether insects have an immunological memory or not. In this study, we found that priming silkworm with E. coli increased clearance of living E. coli cells in the E. coli-reinoculated body. Furthermore, we indicated that the elevation of this clearance was not caused by activation of the humoral immune reactions, but probably by activation of the cellular reactions.
