Figure 5From: Trichinella spiralis galectin binding to toll-like receptor 4 induces intestinal inflammation and mediates larval invasion of gut mucosarTsgal up-regulated TLR-4 expression level in Caco-2 cells. A TLR-4 transcription level of Caco-2 cells incubated with rTsgal, IIL CAg and LPS. B TLR-4 expression level of Caco-2 cells incubated with rTsgal, IIL CAg and LPS. TLR-4 expression level of Caco-2 cells was obviously up-regulated after rTsgal binds to TLR-4 receptor in the cells. *P < 0.01 compared to the PBS group.Back to article page
