Abstract

Mosquitoes are the most important vectors of human pathogens, transmitting a wide range of emerging and re-emerging infectious diseases. In this scenario, the Aedes aegypti is a major mosquito species and transmits diseases such as yellow fever, Chikungunya fever and dengue fever, and more than half of the world population lives in risk areas. In order to successfully nourish themselves, hematophagous mosquitoes find two main challenges once they break the skin's physical integrity: a) the hemostasis and; b) the immunological system of their hosts. During the evolution process, these insects developed a salivary cocktail with an arsenal of molecules presenting several pharmacological effects. However, while the anti-hemostatic activities from saliva of hematophagous vectors are better understood, very few are known about its effects on immunity. Several works have been demonstrated that vector's saliva has an essential role in transmitting pathogens, confirming its immunomodulatory activities. Nevertheless, the mechanisms by which the saliva acts on immunity have not been totally uncovered and almost nothing is currently published in the case of Ae. aegypti. The aim of this project is to investigate the activities of Ae. aegypti saliva on the differentiation, maturation and function of dendritic cells. Considering the importance of these cells to the link of innate and acquired immune responses, the results generated by this work might contribute to the understanding of how Ae. aegypti saliva affects its host's immunity and consequently its role to disease transmission.
