Hepatitis D virus is a unique human pathogen. With a circular, negative stranded RNA genome of ~1700 nucleotides, it is the smallest known human virus. Formation of the HDV particle depends on co-infection of cells with a helper virus, hepatitis B virus. Once thought to be specific for humans, related ...

Viral infection of vertebrates leads to the production of antibodies, and some of these can block virus infection by a process that is called neutralization. Antibodies can neutralize viral infectivity in a number of ways: they may impair virus entry into cells, and even cause degradation of the capsid in ...

When we are born, our blood contains antibodies that we have inherited from our mothers. They are transferred across the placenta and provide protection from infection until IgG production begins around 15 weeks after birth. Can we exploit such antibody transfer by vaccinating pregnant mothers to protect newborns against infectious ...
