Figure 7. (-)-Hopeaphenol inhibits secretion and expression of the P. aeruginosa T3SS effector protein ExoS.

Figure 7

The T3SS was induced in wild-type P. aeruginosa, strain PAK, by removal of Ca2+ from the medium and (-)-hopeaphenol was added. After 3 hours of incubation the secretion and expression of the T3SS effector protein ExoS was measured by western analysis and compared to the DMSO control.
