HCV invades cells in the body by binding to specific receptors on the cell, enabling the virus to enter it.2 Once inside, HCV hijacks functions of the cell known as transcription, translation and replication, which enables HCV to make copies of its viral genome and proteins, allowing the virus to spread to other sites of the body.2 When HCV enters the host cell, it releases viral (+) RNA that is transcribed by viral RNA replicase into viral -LRB--) RNA, which can be used as a template for viral genome replication to produce more (+) RNA or for viral protein synthesis.

These so - called broadly neutralizing antibodies (bNAbs) do little to help the people who produce them, but their existence indicates that mutations have created an increasingly diverse population of the virus, which in turn has pushed the immune system to evolve a response that is both more potent and works against more variants.

Analyzing this woman's virus for their current study, the researchers found that it contained mutations in four amino acids in the envelope protein, two of which, when introduced into unrelated strains of HIV in the laboratory, rendered each virus sensitive to a number of antibodies produced in people infected with HIV, including those directed to more conserved regions.
