Triatoma dimidiata salivary glands LC-MSMS

The reduviid bug Triatoma dimidiata is an important Chagas disease vector widely distributed along Central America. This insect has great capability for domestic adaptation as the majority of specimens caught inside human dwellings or in peridomestic areas in Central America fed human blood. Within this context, exploring the salivary compounds that overcome host haemostatic and immune responses to assist blood-feeding is of great scientific interest. Our aim is to provide a deeper insight into T. dimidiata salivary gland molecules that may contribute to its haematophagic habit. We realized T. dimidiata salivary transcriptomic analysis and complemented it through proteomics, disclosing the set complexity of 119 secreted proteins. The large-scale approach used enriches the pharmacologically active molecules database and improves our knowledge about the complexity of salivary compounds from haematophagous vectors and their biological interactions.
