Human trichomonosis, infection with Trichomonas vaginalis, is the most common non-viral sexually transmitted disease in the world. The host-parasite interaction and pathophysiological processes of trichomonosis remain incompletely understood. This review focuses on the advancements reached in the area of the pathogenesis of T. vaginalis, especially in the role of the cysteine proteinases. It highlights various approaches made in this field and lists a group of trichomonad cysteine proteinases involved in diverse processes such as invasion of the mucous layer, cytoadherence, cytotoxicity, cytoskeleton disruption of red blood cells, hemolysis, and evasion of the host immune response. A better understanding of the biological roles of cysteine proteinases in the pathogenesis of this parasite could be used in the identification of new chemotherapeutic targets. An additional advantage could be the development of a vaccine in order to reduce transmission of T. vaginalis.
Résumé
La trichomonose humaine, infection par Trichomonas vaginalis, est la maladie sexuellement transmissible non-virale la plus courante dans le monde. L’interaction hôte-parasite et les processus physiopathologiques de la trichomonose restent mal compris. Cette revue se concentre sur les progrès obtenus dans le domaine de la pathogenèse de T. vaginalis, spécialement le rôle des cystéine-protéases. Elle met en lumière les différentes approches dans ce domaine et donne la liste d’un groupe de cystéine-protéases de T. vaginalis impliquées dans des processus divers tels que l’invasion de la couche de mucus, la cytoadhérence, la cytotoxicité, la disruption du cytosquelette des globules rouges, l’hémolyse et l’échappement envers la réponse immunitaire de l’hôte. Une meilleure compréhension des rôles biologiques des cystéine-protéinases dans la pathogenèse de ce parasite pourrait être utile pour l’identification de nouvelles cibles chimiothérapeutiques. Un avantage supplémentaire pourrait être le développement d’un vaccin en vue de réduire la transmission de T. vaginalis.
