Viruses 2019 Feb 12;11(2). Epub 2019 Feb 12.

Department of Immunology, School of Medicine, The University of Connecticut Health Center, Farmington, CT 06030, USA.

Mosquito-borne diseases constitute a large portion of infectious diseases, causing more than 700,000 deaths annually. Mosquito-transmitted viruses, such as yellow fever, dengue, West Nile, chikungunya, and Zika viruses, have re-emerged recently and remain a public health threat worldwide. Global climate change, rapid urbanization, burgeoning international travel, expansion of mosquito populations, vector competence, and host and viral genetics may all together contribute to the re-emergence of arboviruses.

Yellow fever virus modulates cytokine mRNA expression and induces activation of caspase 3/7 in the human hepatocarcinoma cell line HepG2.

Arch Virol 2019 Feb 6. Epub 2019 Feb 6.

Instituto Evandro Chagas, Rodovia BR-316 Km7, Levilândia, Ananindeua, PA, CEP 67030-000, Brazil.

Yellow fever virus (YFV) penetrates the skin through the bite of a vector mosquito and spreads to various organs, mainly the liver, where it causes lesions and induces necrosis and apoptosis. We evaluated the mRNA expression of various cytokines and the activation of caspases in HepG2 cells infected with YFV. We observed that interferon-α (IFN-α) expression decreased and IFN-β, transforming growth factor (TGF)-β IIIR, interleukin (IL)-6, and IL-8 expression increased in cells infected with genotype 1.

Uncovering Flavivirus Host Dependency Factors through a Genome-Wide Gain-of-Function Screen.

Viruses 2019 Jan 15;11(1). Epub 2019 Jan 15.

Viral Genomics and Vaccination Unit, UMR3569 CNRS, Virology department, Institut Pasteur, 75015 Paris, France.

Flaviviruses, such as dengue (DENV), West Nile (WNV), yellow fever (YFV) and Zika (ZIKV) viruses, are mosquito-borne pathogens that present a major risk to global public health. To identify host factors that promote flavivirus replication, we performed a genome-wide gain-of-function cDNA screen for human genes that enhance the replication of flavivirus reporter particles in human cells. The screen recovered seventeen potential host proteins that promote viral replication, including the previously known dolichyl-diphosphooligosaccharide--protein glycosyltransferase non-catalytic subunit (DDOST).

Ocular Findings in Yellow Fever Infection.

JAMA Ophthalmol 2019 Jan 10. Epub 2019 Jan 10.

Vision Institute, Department of Ophthalmology, Paulista Medical School, Federal University of São Paulo, São Paulo, Brazil.

Importance: Yellow fever virus (YFV) is a reemerging, potentially lethal arboviral disease that has been occurring recently in Africa and South America. Poor levels of immunization have facilitated the viral spread in southeastern Brazil, leading to an unprecedented outbreak that started in late 2016. Although human cases have been linked to sylvatic mosquitoes, the concern is that YFV may spread to urban centers infested with Aedes aegypti and Aedes albopictus mosquitoes and start a true urban cycle.

Kanamycin detection at graphene quantum dot-decorated gold nanoparticles in organized medium after solid-phase extraction using an aminoglycoside imprinted polymer.

MethodsX 2018 30;5:1605-1612. Epub 2018 Nov 30.

Department of Chemistry, Pontifical Catholic University of Rio de Janeiro (PUC-Rio), Rio de Janeiro, 22451-900, Brazil.

This is a description of the indirect determination of kanamycin sulfate though the photoluminescence enhancement of an aqueous dispersion of amino-functionalized graphene quantum dots (amino-GQDs) coupled with gold nanoparticles (AuNPs) in a cationic surfactant-rich medium. Specifically, cetyltrimethylammonium bromide (CTAB) was used as the cationic surfactant in our work. Previously, solid phase extraction with a cartridge packed with aminoglycoside-selective imprinted polymer ensured selectivity in kanamycin determination in yellow-fever vaccine and veterinary pharmaceutical samples.

RNA Structure Duplication in the Dengue Virus 3' UTR: Redundancy or Host Specificity?

MBio 2019 Jan 8;10(1). Epub 2019 Jan 8.

Fundación Instituto Leloir-CONICET, Buenos Aires, Argentina

Flaviviruses include a diverse group of medically important viruses that cycle between mosquitoes and humans. During this natural process of switching hosts, each species imposes different selective forces on the viral population. Using dengue virus (DENV) as model, we found that paralogous RNA structures originating from duplications in the viral 3' untranslated region (UTR) are under different selective pressures in the two hosts.
