Outline of Final Research Achievements

The coordinated actions of lymphocytes, innate immune cells, epithelium, and smooth muscles can play an important role in host intestinal immune function and homeostasis. We investigated type2 immune responses in early stage against nematode parasite in the murine intestine. The results suggested that innate immune cells initiate production of type2 cytokines, communicate with other immune cells including T cells and mediate adaptive pathogen-specific immune responses to eliminate pathogens. INFgamma; might regulate the termination of innate immune responses in the early stage. While, Th2 play mainly in memory responses against re-infection of nematode parasite.
