Hibits Th2 differentiation. Th2-related cytokines include IL-10. IL-10 is an inhibitor of immunity cell differentiation and immune response. In the transgenic group, IFN-c increased under LPS stimulation. Soon after that, IL-10 transcription became up-regulated and this up-regulation lasted for at least 72 hours. IL-10 acts on antigenpresenting cells to inhibit the release of cytokines and regulates TH1/TH2 balance. Under LPS stimulation, both inflammatory and anti-inflammatory cytokines were expressed. This protected tissue from excessive inflammation. Monocytes play an important role in non-specific and specific immunological responses, which protect organisms from pathogens.

Macrophages and monocytes take a portion of the debris left over from the digestion of a pathogen and present it as an antigen to the adaptive immune system [32]. Phagocytosis of apoptotic inflammatory cells is one of mechanisms by whichinflammation is eliminated [33]. TLR4 signaling was found to be necessary and sufficient for phagocytosis by monocytes. Phagocytosis was found to be correlated to the immune reaction. The present study indicated that TLR4 overexpression increased theFigure 9.
