PHluorin-conjugated secondary nanobodies as a tool for measuring synaptic vesicle exo- and endocytosis

Authors Georgiev SV, Rizzoli SO Journal Scientific Reports Citation Sci Rep 15, 10093 (2025). Abstract Neuronal communication relies on synaptic vesicle recycling, which has long been investigated by live imaging approaches. Synapto-pHluorins, genetically encoded reporters that incorporate a pH-sensitive variant of GFP within the lumen of the synaptic vesicle, have

Artistic depiction of the 3D structure of Nipah virus RNA polymerase in the active state. The structure of the Nipah virus RNA polymerase is shown as a transparent surface representation (L protein in green, P protein in orange). The viral RNA, which serves as a template for the RNA polymerase, is shown in blue, the newly produced product RNA in red. The nucleotide substrate is shown in yellow. © Fernanda Sala / UMG

Molecular 3D structure of viral “copying machine” deciphered

Researchers at the University Medical Center Göttingen (UMG) and the Max Planck Institute (MPI) for Multidisciplinary Sciences have shown, for the first time, how the genetic material of the Nipah virus replicates in infected cells. The virus can cause fatal encephalitis in humans. Using cryo-electron microscopy, the team led by
