Chaperone fusion proteins aid entropy-driven maturation of class II viral fusion proteins [PDF]
Trends in Microbiology, 2014 Class II viral fusion proteins are present on the envelope of flaviviruses and togaviruses, viruses that often cause tropical and subtropical diseases. These proteins use a second membrane protein as a molecular chaperone to assist their folding and to ensure proper function during viral assembly, maturation, and infection.

Single-Molecule Analysis of a Viral Fusion Protein Illuminates a Fusion-Active Intermediate State [PDF]
Cell, 2018 The influenza virus hemagglutinin (HA) fusion glycoprotein mediates viral entry into host cells through its receptor binding and membrane fusion activities. In this issue of Cell, Das et al. use single-molecule Förster resonance energy transfer (smFRET) to monitor HA conformational dynamics.

Structure and Neutralization of Viral Fusion Proteins
, 2023 Emerging infectious diseases remain persistent threats that are challenging to predict. Humanity has faced many terrible pandemics and will face more, but to pinpoint the specific time and place of an outbreak, the type of pathogen, and the consequences is effectively impossible.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
FEBS Letters, EarlyView.This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Characterization of a structural intermediate of flavivirus membrane fusion.
PLoS Pathogens, 2007 Viral membrane fusion proceeds through a sequence of steps that are driven by triggered conformational changes of viral envelope glycoproteins, so-called fusion proteins.

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Hydrophobic-at-Interface Regions in Viral Fusion Protein Ectodomains
Bioscience Reports, 2000 In this chapter we shall describe how to apply the hydrophobicity-at-interface scale, as proposed by Wimley and White [Wimley, W. C. and White, S. H. (1996) Nature Struct. Biol. 3:842–848], to the detection of amino acid sequences of viral envelope glycoproteins putatively engaged in interactions with the target membranes.

FEBS Letters, EarlyView.Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Biophysical approaches for studying viral entry
FEBS Letters, EarlyView.Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the
