Effective interventions may prevent disease transmission in changing climate
(PLOS) Aedes aegypti are the primary vector for mosquito-borne diseases such as dengue fever, however the effects of climate change-related weather anomalies on mosquito populations is not well understood. A study published in PLOS Neglected Tropical Diseases by Cameron Nosrat at Stanford University, United States and colleagues suggests that early interventions may prevent disease transmission even as extreme climate events may increase the abundance of Ae. aegypti populations.

Study of mosquito protein could lead to treatments against life-threatening viruses
(NIH/National Institute of Environmental Health Sciences) The mosquito protein AEG12 strongly inhibits the family of viruses that cause yellow fever, dengue, West Nile, and Zika and weakly inhibits coronaviruses, according to scientists at the National Institutes of Health (NIH) and their collaborators. The researchers found that AEG12 works by destabilizing the viral envelope, breaking its protective covering. The findings could lead to therapeutics against viruses that affect millions of people around the world. The research was published online in PNAS.

A broadly protective antibody that targets the flavivirus NS1 protein
There are no approved flaviviral therapies and the development of vaccines against flaviruses has the potential of being undermined by antibody-dependent enhancement (ADE). The flavivirus nonstructural protein 1 (NS1) is a promising vaccine antigen with low ADE risk but has yet to be explored as a broad-spectrum therapeutic antibody target. Here, we provide the structural basis of NS1 antibody cross-reactivity through cocrystallization of the antibody 1G5.3 with NS1 proteins from dengue and Zika viruses. The 1G5.3 antibody blocks multi-flavivirus NS1-mediated cell permeability in disease-relevant cell lines, and therapeuti...

Structural basis for antibody inhibition of flavivirus NS1-triggered endothelial dysfunction
Medically important flaviviruses cause diverse disease pathologies and collectively are responsible for a major global disease burden. A contributing factor to pathogenesis is secreted flavivirus nonstructural protein 1 (NS1). Despite demonstrated protection by NS1-specific antibodies against lethal flavivirus challenge, the structural and mechanistic basis remains unknown. Here, we present three crystal structures of full-length dengue virus NS1 complexed with a flavivirus–cross-reactive, NS1-specific monoclonal antibody, 2B7, at resolutions between 2.89 and 3.96 angstroms. These structures reveal a protective mecha...

The Zika pandemic sparked intense interest in whether immune interactions among dengue virus serotypes 1 to 4 (DENV1 to -4) extend to the closely related Zika virus (ZIKV). We investigated prospective pediatric cohorts in Nicaragua that experienced sequential DENV1 to -3 (2004 to 2015), Zika (2016 to 2017), and DENV2 (2018 to 2020) epidemics. Risk of symptomatic DENV2 infection and severe disease was elevated by one prior ZIKV infection, one prior DENV infection, or one prior DENV infection followed by one ZIKV infection, compared with being flavivirus-naïve. By contrast, multiple prior DENV infections reduced dengue ris...
