The mechanism triggering HBV membrane fusion involves ERp57, a cellular protein disulfide isomerase, and ultimately leads to the exposition of a fusion peptide that was identified in the pre-S1 determinant.

Human antibodies that neutralize New World hantaviruses are promising for prevention or treatment of these high-priority emerging pathogens carried by rodents and transmitted to humans by aerosolized excreta or, in rare cases, person-to-person contact.

How large-scale single mosquito metatranscriptomics can define the mosquito’s complex microbiota and its blood meal sources, and contribute critical epidemiological information needed to control vector borne disease transmission, is shown.

Evolutionary innovation and turnover in the IFIT1 antiviral gene family has led to diverse repertoires of antiviral specificity across mammals.

An integrated cryoEM and X-ray crystallography study resolves the structural basis for antibody-mediated targeting of the hantavirus fusion glycoprotein and provides insight into the conformational landscape of the hantavirion surface.

Conformational flexibility in HIV-1 capsid, provided by cyclophilin A binding, facilitates evasion of capsid-targeting restriction factor MxB, while allowing sequence change to facilitate cytotoxic T-cell evasion.

A mouse-adapted strain of Crimean-Congo hemorrhagic fever virus that recapitulates human disease in wild-type mice significantly improves our ability to study Crimean-Congo hemorrhagic fever virus pathogenesis.

The high-resolution structure of a filamentous flexible plant virus shows that there is structural homology between its coat protein and the nucleoproteins of an unrelated group of enveloped RNA animal viruses.

Hantavirus spikes are related laterally by 2-fold Gc contacts that can be disulfide-linked and display a temperature-dependent dynamic behavior at neutral pH, exposing and masking the Gc fusion loops.
