In contrast, when neonates are infected, more than 90% become persistently infected, suffering differing degrees of chronic liver disease. Activation of immunity plays a central role in host-virus interactions, greatly influencing viral replication and the clinical outcome of infection. Although all of the specific mechanisms and consequences of this interaction have not been elucidated, the purpose of this article is to describe the basic arms of the ..
