Sylvatic cycles of arboviruses in non-human primates

Arboviruses infecting people primarily exist in urban transmission cycles involving urban mosquitoes in densely populated tropical regions. For dengue, chikungunya, Zika and yellow fever viruses, sylvatic (for...

Conclusion and Perspectives Arbovirus infections, such as CHIKV, have been growing worldwide and are becoming a major public health problem, especially in immuno-compromised classes such as children and the elderly. CHIKV is dangerous since it can cause arthritis, fever and other impairments, making it necessary to seek new ways to counter the proliferation of this virus. Knowing the vector’s competence is fundamentally important, including an understanding of the vector virus interaction and the modulation of this interaction. Despite advances in the knowledge of mosquito competence in the transmission of CHIKV, li...

Abstract With almost half of the world population living at risk, tropical infectious diseases cause millions of deaths every year in developing countries. Considering the lack of economic prospects for investment in this field, approaches aiming the rational design of compounds, such as structure-based drug discovery (SBDD), fragment screening, target-based drug discovery, and drug repurposing are of special interest. Herein, we focused in the advances on the field of SBDD targeting arboviruses such as dengue, yellow fever, zika and chikungunya enzymes of the RNA replication complex (RC) and enzymes involved in a...

Abstract Yellow fever mosquito Aedes aegypti transmits many devastating arthropod-borne viruses (arboviruses), such as dengue virus, yellow fever virus, Chikungunya virus, and Zika virus, which cause great concern to human health. Mosquito control is an effective method to block the spread of infectious diseases. Ae. aegypti uses its innate immune system to fight against arboviruses, parasites, and fungi. In this review, we briefly summarize the recent findings in the immune response of Ae. aegypti against arboviral and entomopathogenic infections. This review enriches our understanding of the mosquito immune syst...
