Conserved dimerization architecture in C‐type lectins from virus‐vector mosquitoes

The FEBS Journal, EarlyView.
C‐type lectins (CTLs) are involved in the detection of viral/microbial carbohydrates. We studied a family of soluble CTLs in the mosquito Aedes aegypti, which acts as a vector for viruses like dengue and Zika. Using crystallography, biophysics, and structure prediction approaches, we found that these proteins consistently pair together in the same ...

Advances in Cytosolic dsRNA Sensing of Viral Infections

Immunology &Cell Biology, EarlyView.
Activation of cytosolic dsRNA sensors by viral infection generates multiple outcomes. dsRNA generated during viral infection, either of viral origin or from endogenous sources, can activate multiple cytosolic dsRNA sensors. Activation of PKR critically induces protein translation shutdown via phosphorylation of eukaryotic translation initiation factor ...

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

Medical and Veterinary Entomology, EarlyView.
The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

A neonatal nonhuman primate model of gestational Zika virus infection with evidence of microencephaly, seizures and cardiomyopathy.

PLoS ONE, 2020
Zika virus infection during pregnancy is associated with miscarriage and with a broad spectrum of fetal and neonatal developmental abnormalities collectively known as congenital Zika syndrome (CZS). Symptomology of CZS includes malformations of the brain

The inoculum dose of Zika virus can affect the viral replication dynamics, cytokine responses and survival rate in immunocompromised AG129 mice

Molecular Biomedicine
Zika virus, a mosquito-borne arbovirus, has repeatedly caused large pandemics with symptoms worsening from mild and self-limiting diseases to Guillain–Barré syndrome in adults and fetal microcephaly in newborns.
