Reassessing the role of defensin in the innate immune response of the mosquito, Aedes aegypti.

Transmission of African Horse-Sickness by Means of Mosquito Bites and Replication of the Virus in Aedes aegypti

Phylogenetic Analysis of Aedes aegypti Based on Mitochondrial ND4 Gene Sequences in Almadinah, Saudi Arabia

Background: Aedes aegypti is the main vector of the yellow fever and dengue virus. This mosquito has become the major indirect cause of morbidity and mortality of the human worldwide. Dengue virus activity has been reported recently in the western areas of Saudi Arabia. There is no vaccine for dengue virus until now, and the control of the disease depends on the control of the vector. Objectiv...

Temperature-mediated differential expression of immune and stress-related genes in Aedes aegypti larvae.

The mechanisms by which natural populations of vector mosquitoes cope with daily and seasonal fluctuations in temperature are poorly understood. We examined the effect of water temperature on expression of stress and immune-related genes in Aedes aegypti larvae. Aedes aegypti 3rd instars were exposed for 24 h to one of 7 constant temperatures (10 degrees C, 15 degrees C, 20 degrees C, 25 degree...

The Aedes aegypti Toll Pathway Controls Dengue Virus Infection

Aedes aegypti, the mosquito vector of dengue viruses, utilizes its innate immune system to ward off a variety of pathogens, some of which can cause disease in humans. To date, the features of insects' innate immune defenses against viruses have mainly been studied in the fruit fly Drosophila melanogaster, which appears to utilize different immune pathways against different types of viruses, in ...

Dengue serotype-specific immune response in Aedes aegypti and Aedes albopictus

BACKGROUND Dengue viruses (DENV) are considered one of the most important emerging pathogens and dengue disease is a global health threat. The geographic expansion of dengue viruses has led to co-circulation of all four dengue serotypes making it imperative that new DENV control strategies be devised. OBJECTIVES Here we characterize dengue serotype-specific innate immune responses in Aedes ae...
