Comparison of the Immunosuppressive Activity between Cuticle Coat Proteins and Secrete Proteins from Steinernema glaseri
摘要
Abstract
Both surface coat proteins （SCPs） and secrete proteins （SPs） from Steinernema glaseri infective juveniles are able to suppress insect immune activities and were proved to play important roles in promoting infection of entomopathogenic nematodes. However, they are different in activities because of their different constituents. In this study, the SCPs were extracted with ethanol and the SPs were induced by Galleria me[lonella homogenates, then the similarity and difference between them were compared. Result indicated that no matter in vivo or in vitro, both kinds of proteins have the ability to suppress insect immunity, but the activity of SPs is more powerful than that of SCPs. Our studies provide scientific evidence for further study of the relationship between entomopathogenic nematode and insect, and the immunosuppressive mechanism of Steinernema glaseri.关键词
