West Nile (WN) virus infection of humans is frequently asymptomatic, but can also lead to WN fever or neuroinvasive disease. CD4 T cells and B cells are critical in the defense against WN virus, and neutralizing antibodies, which are directed against the viral glycoprotein E, are an accepted correlate of protection. For the efficient production of these antibodies, B cells interact directly with CD4 helper T cells that recognize peptides from E or the two other structural proteins (capsid-C and membrane-prM/M) of the virus. However, the specific protein sites yielding such helper epitopes remain unknown. Here, we explored ...

Yes. However, very probably not because of the novel coronavirus that has appeared in China. This seems to be front page headlines in every media outlet on the planet, and  the World Health Organization has convened a meeting to decide whether to declare an official Global Health Emergency.This sort of flapdoodle happens every time a novel pathogen appears. Back when I lived in the Hub of the Universe a mosquito-borne disease called West Nile virus appeared (having formerly been large confined to, yes, west of the Nile). For weeks, every time a new case was identified it would be on the front page of the Boston Globe....

Authors: Maucourant C, Queiroz GAN, Samri A, Grassi MFR, Yssel H, Vieillard V Abstract Zika virus (ZIKV) is an emerging arbovirus that causes a mosquito-borne disease. Although infection with ZIKV generally leads to mild disease, its recent emergence in the Americas has been associated with an increase in the development of the Guillain-Barré syndrome in adults, as well as with neurological complications, in particular congenital microcephaly, in new-borns. Over the five past years, through the combined efforts of the scientific community, comprehensive remarkable progress aimed at deciphering the clinical, ...

(Wiley) Emerging viral infections -- from bird flu to Ebola to Zika infections -- pose major threats to global public health, and understanding their origins can help investigators design defensive strategies against future outbreaks. A new study published in the Journal of Medical Virology provides important insights on the potential origins of the most recent outbreak of viral pneumonia in China, which started in the middle of December and now is spreading to Hong Kong, Singapore, Thailand, and Japan.

Zika virus (ZIKV), a flavivirus, has recently emerged as a significant pathogen.1 In 2016, the World Health Organization recognized it as a global health emergency due to its spread throughout the Americas and its links to an increase in the number of neonates with congenital microcephaly.2 Subsequently, ZIKV was identified as the causative pathogen of congenital ZIKV infection in which severe neurological impairment and brain abnormalities may occur.3 It has been estimated that, among pregnant women with known maternal ZIKV infection during pregnancy, approximately a quarter of foetuses will become congenitally infected, ...

AbstractGuillain –Barré syndrome (GBS) is an acute-onset, immune-mediated polyradiculoneuropathy, often precipitated by an antecedent infection. An association of GBS with vector-borne viral infections has been suggested, with evidence for the involvement of Zika, Dengue, Chikungunya and West Nile virus (WNV). Th is prospective case–control study was conducted to identify vector-borne viral infections in GBS. Thirteen individuals newly diagnosed as GBS were enrolled. Disease severity, prognostic factors and nerve conduction patterns were assessed. Eleven individuals with non-infectious conditions requiri...

Zika virus (ZIKV) is an emerging arthropod-borne virus and belongs to the Flaviviridae family. The infection of ZIKV has become the global health crisis because of its rapid spread and association with severe neurological disorders, including congenital microcephaly and Guillain-Barre Syndrome. To identify host factors contributing to ZIKV pathogenesis, transcriptomic landscape in ZIKV-infected cells was examined with mRNA microarray analysis and we observed that the expression of hydroxycarboxylic acid receptor 2 (HCAR2) could be significantly induced by ZIKV infection. By utilizing two IRE1 inhibitors and XBP1-specific s...
