In this study, three structurally distinct disintegrins (flavoridin, echistatin, kistrin) were used as molecular probes to further characterize the molecular mechanisms underlying Yersinia enterocolitica infection of host cells. The activity of the three disintegrins on Y. enterocolitica uptake into fibronectin-adherent HeLa cells was evaluated at disintegrin doses which were non-cytotoxic and unable to induce cell detachment. Flavoridin resulted to be the most effective in inhibiting bacterial entry into host cells; echistatin was almost 50% less effective than flavoridin, whereas kistrin was definitely inactive. Our results suggest that alpha(5)beta(1) integrin receptor, which binds flavoridin with higher affinity than the other two disintegrins, plays a major role in Y. enterocolitica uptake into HeLa cells. Furthermore, flavoridin binding to this integrin prevented the disruption of the functional complex FAK-Cas, which occurs in the Y. enterocolitica uptake process.
