Methods Related to the Immunopathogenesis of Vulvovaginal Candidiasis and Associated Neutrophil Anergy

Vulvovaginal candidiasis (VVC) is a common mucosal disease, caused primarily by Candida albicans that affects up to 75% of women of childbearing age. The pathogenesis of VVC and recurrent VVC (RVVC) is largely understood after decades of research. In this regard, an immunopathological response involving the migration of neutrophils that become dysfunctional (anergic) in the vaginal environment leads to the symptomatic conditions. However, immunotherapeutic strategies to correct the immunopathogenesis are still elusive. Much of the mechanistic discoveries have been uncovered using the established mouse model of chronic VVC. This chapter details the methods widely used for the mouse model of experimental VVC and associated outcome measures of the immunopathologic response and resulting symptomatic condition and focuses further on assays used to demonstrate "neutrophil anergy" in the model. These methods may serve as a source or resource for further experimentation with the ultimate goal to reduce or eliminate VVC/RVVC.
