Lactiplantibacillus plantarum E51 protects against Clostridioides difficile-induced damages on Caco-2 intestinal barrier functions

Sumario: | Clostridioides difficile (C. difficile) infection is associated with high morbidity and mortality. This study aimed to evaluate the protective effect of Lactiplantibacillus plantarum E51 (L. plantarum E51) on C. difficile infection using the Caco-2 monolayer in vitro model. Caco-2 cells were infected with C. difficile in the presence/absence of L. plantarum E51 or Lacticaseibacillus rhamnosus GG (LGG). Caco-2 intestinal barrier functions, such as monolayer integrity, IL-8 secretion, and tight junction protein expression, were quantified to investigate the extent to which L. plantarum E51 protected against C. difficile infection in vitro. Furthermore, inhibition of C. difficile adhesion to Caco-2 cells by L. plantarum E51 was explored using competition, exclusion, and displacement assays. The results indicated that L. plantarum E51 inhibited C. difficile growth, ameliorated C. difficile-caused decrease in transepithelial/ transendothelial electrical resistance, attenuated C. difficile-induced IL8 secretion, and upregulated claudin-1 protein expression that was inhibited by C. difficile. Moreover, L. plantarum E51 suppressed C. difficile adhesion to Caco-2 cells. In conclusion, these findings demonstrated that L. plantarum E51 substantially protected against C. difficile-induced damages on intestinal barrier functions in Caco-2 cells. The probiotic potential of L. plantarum E51 against C. difficile infection warrants further investigation. |
