Article Title: Houttuynia cordata extract protects against Salmonella infection by targeting type III secretion system 1

doi: 10.1016/j.psj.2026.106937

Figure Lengend Snippet: HCE suppresses the adhesion and invasion of Salmonella in Caco-2 cells. A CCK-8 assay (A) was conducted to evaluate the cytotoxicity of HCE in Caco-2 cells. The effects of HCE on the adhesion (B, D) and invasion (C, E) of ST (B-C) and SP (D-E) to Caco-2 cells were examined at an MOI of 100 (n = 5). Immunofluorescence microscopy was performed to visualize the inhibitory effect of HCE (150 µg/mL) on the invasion of ST (F) and SP (G) in Caco-2 cells. Caco-2 cells infected with the ST Δ invA strain, which was used as a negative control because of its T3SS-1 deficiency showed significantly reduced invasion. ST, Salmonella Typhimurium. SP, Salmonella Pullorum . HCE, Houttuynia cordata extract.
