Glucose-restriction increases Trichomonas vaginalis cellular damage towards HeLa cells and proteolytic activity of cysteine proteinases (CPs), such as TvCP2.

Trichomonas vaginalis induces cellular damage to the host cells (cytotoxicity) through the proteolytic activity of multiple proteinases of the cysteine type (CPs). Some CPs are modulated by environmental factors such as iron, zinc, polyamines, etc. Thus, the goal of this study was to assess the effect of glucose on T.
