Abstract:
Inspite of the available antiviral therapy, hepatitis C virus (HCV) remains a global health burden and a prophylactic vaccine would help to eliminate the risk to develop chronic liver diseases. Structural insights into the function of the glycoproteins E1 and E2 in virus entry and the interplay with the host's humoral immune response are key for informed vaccine development. We review recently reported structural insights into receptor binding of HCV glycoproteins and the assembly of an intact membrane-bound E1-E2 heterodimer. These data are used together with available functional data to draw a simplified model of virus entry, which highlights gaps in our current knowledge that warrant further research to fully understand this process at the atomic level.
Insights

NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...
