Witryna25 wrz 2024 · Abstract. Cell entry of enveloped viruses requires specialized viral proteins that mediate fusion with the host membrane by substantial structural rearrangements from a metastable pre- to a stable postfusion conformation. This metastability renders the herpes simplex virus 1 (HSV-1) fusion glycoprotein B (gB) highly unstable such that it ... Witryna16 lis 2024 · Wirus HSV zbudowany jest z białek tworzących kasyd (płaszcz) o kształcie dwudziestościanu oraz z kwasu nukleinowego - dwuniciowego DNA, który koduje ok. 100 polipeptydów. Infekcja wirusem opryszczki zwykłej jest bardzo powszechna, a wirus ten często bytuje w naszym organizmie i nie powoduje wystąpienia objawów.
