Real-Time Assessment of Health-Care Requirements During the Zika Virus Epidemic in Martinique
by Andronico et al.This study showcases the contribution of modeling to inform local health-care planning during an outbreak. Timely studies that estimate the proportion of infected persons that seek care are needed to improve the predictive power of such approaches.
Researchers demonstrate that strategically combining the suppression methods with Wolbachia can generate a sustained control while mitigating the risks of inadvertent exacerbation of the wild mosquito population.
Zika virus causes supernumerary foci with centriolar proteins and impaired spindle positioning
by Wolf et al.The article concludes that infection with Flaviviridae can increase centrosome numbers and impair spindle positioning, thus potentially contributing to microcephaly in the case of Zika.
African and Asian Zika virus strains differentially induce early antiviral responses in primary human astrocytes
by Hamel et al.This study describes for the first time the specific antiviral gene expression in infected primary human astrocytes, the major glial cells within the central nervous system.
Zika virus in asymptomatic blood donors in Martinique
by Gallian et al.This pioneering study suggests that the study of blood donors during outbreaks of emerging pathogens has become a key element of epidemiological surveillance.
Axl Mediates ZIKA Virus Entry in Human Glial Cells and Modulates Innate Immune Responses
by Meertens at al.This study highlights the dual role of Axl during ZIKV infection of glial cells: promoting viral entry and modulating innate immune responses. Therefore, inhibiting Axl function may represent a potential target for future antiviral therapies.
By using the bacterium-free ‘Infectious Subgenomic Amplicons’ (ISA) method, this study provides the scientific community with two simple and performing reverse genetics systems for ZIKV.
Zika and Other Emerging Viruses: Aiming at the Right Target
by Dallmeier & NeytsThe article argues that the off-label use of drugs that may protect against Zika virus-induced brain damage has to be balanced with their risk during pregnancy.
How Did Zika Virus Emerge in the Pacific Islands and Latin America?
by Pettersson et al.Based on comparative ZIKV complete genome phylogenetic analyses and temporal estimates, the authors identify amino acid substitutions that may be associated with increased viral epidemicity, CZVS, and GBS. Reverse genetics, vector competence, and seroepidemiological studies will test the hypothesis that these amino acid substitutions are determinants of epidemic and neurotropic ZIKV emergence.
