Expression of enolase and laminin in the vagina of bacterial vaginosis of mice
Objective To investigate the differences in enolase and laminin levels in vaginal epithelial tissues be-tween mice successfully infected with Gardnerella and mice not infected with Gardnerella,providing information for further exploration of the correlation between enolase and laminin levels and the incidence of bacterial vaginosis.Methods Gardnerella strains isolated,purified,and identified from vaginal secretions of patients with bacterial vaginosis were used to infect the vagina of mice and establish a mouse model of bacterial vaginosis.Successful and failed mice was defined as successful and failed groups,respectively.Differential expression of enolase and laminin in the vaginal epithelial tissue of two groups of mice was detected by Western blot.Modeling success rate was statis-tically analyzed,and the expression differences of enolase and laminin was compared between two groups.Results One strain of Gardnerella vaginalis infected 10 SPF grade KM mice,7 mice met the diagnostic criteria for bacte-rial vaginosis,and 3 mice failed to model,with a success rate of 70％.Western blot was used to detect protein ex-pression levels,and the levels of laminin and enolase in the successfully modeled mouse vaginal epithelial tissue were significantly higher than those in the failed modeling group,with statistical differences between the two groups(P＜0.05).Conclusion Enolase and laminin may be involved in the occurrence of bacterial vaginosis,however,further research is needed to determine the mechanisms through which they trigger the occurrence and development of the disease.
