DENV-1 Titer Impacts Viral Blocking in wMel Aedes aegypti with Brazilian Genetic Background

Viruses
Several countries have been using Wolbachia deployments to replace highly competent native Aedes aegypti populations with Wolbachia-carrying mosquitoes with lower susceptibility to arboviruses such as dengue, Zika, and chikungunya.

In tune with nature: Wolbachia does not prevent pre-copula acoustic communication in Aedes aegypti

Parasites & Vectors, 2018
Background Mosquito-borne diseases are rapidly spreading to vast territories, putting at risk most of the world’s population. A key player in this scenario is Aedes aegypti, a hematophagous species which hosts and transmits viruses causing dengue and ...

Odors: from chemical structures to gaseous plumes [PDF]

, 2020
We are immersed within an odorous sea of chemical currents that we parse into individual odors with complex structures. Odors have been posited as determined by the structural relation between the molecules that compose the chemical compounds and their ...

Midgut microbiota diversity and interactions shift when field Aedes aegypti mosquitoes carry the wMel strain of Wolbachia pipientis

Communications Biology
The gut microbiota plays a crucial role in mosquito biology and immunity, but the effects of Wolbachia on microbiota diversity remain unclear. In Brazil, wMel-carrying Aedes aegypti were first deployed in 2015 to replace wild populations and block ...

Alphaviral Capsid Proteins Inhibit Stress Granule Assembly via Competitive RNA Binding With G3BP1

Advanced Science, EarlyView.
Stress granules exert antiviral functions. This study illustrates a conserved function of alphaviral capsid proteins in modulating stress granules. Oligomerization mediated by a helical motif coupled with a positively charged intrinsically disordered region (IDR) directly competes with G3BP1 for RNA binding, thereby disrupting G3BP1‐RNA liquid–liquid ...

Delayed mortality effects cut the malaria transmission potential of insecticide resistant mosquitoes [PDF]

, 2016
Malaria transmission has been substantially reduced across Africa through the distribution of long-lasting insecticidal nets (LLINs). However, the emergence of insecticide resistance within mosquito vectors risks jeopardizing the future efficacy of this ...

IgG‐Bridging–Seeded Synergistic Aggregation of SARS‐CoV‐2 Spikes Underlies Potent Neutralization by a Low‐Affinity Antibody

Advanced Science, EarlyView.
Low‐affinity antibodies are frequently disregarded in discovery pipelines. This work reports P5‐1C8, a Class 1 SARS‐CoV‐2 antibody with weak trimer binding (KD‐to‐IC50 > 3700‐fold) yet potent neutralization of Omicron JN.1. Structural, biophysical, functional, and coarse‐grained simulations collectively demonstrate that transient inter‐spike IgG ...

Discovery of an Adaptive Neuroimmune Response Driving Itch and Fast Tick Removal with Implications for Preventing Pathogen Transmission

Advanced Science, EarlyView.
Doehl et al. discovered an adaptive neuroimmune mechanism that induces itch in tick‐exposed guinea pigs, enabling rapid tick removal. This itch‐induced tick removal (IITR) is mediated by an adaptive cellular immune response and is independent of IgG, IgE, or TRPV1.

Conceptual model of salt marsh management on Merritt Island National Wildlife Refuge, Florida: final report [PDF]

, 1985
Diking and holding water on salt marshes ("impounding" the marsh) is a management technique used on Merritt Island National Wildlife Refuge (MINWR) and elsewhere in the Southeast to: a) prevent the reproduction of saltmarsh mosquitos, and b) attract ...
