Fig. 5From: An avian influenza A (H7N9) virus vaccine candidate based on the fusion protein of hemagglutinin globular head and Salmonella typhimurium flagellinTLR5 activity of the fusion protein. Each of the proteins was tested for TLR5 activity using HEK-293-mTLR5 cells. HA1-2-fliC was compared to HA1-2 alone, using 100 ng/ml of each, and flagellin (Enzo Life Sciences, USA) was used as a positive control. Data are presented as mean ± SEM of IL-8 (pg/ml); *p < 0.05, **p < 0.01, *** p < 0.001Back to article page
