THE MECHANISM OF VIRUS ATTACHMENT TO HOST CELLS
WebViral fusion proteins are key components of virus particles that enable a virus to enter an animal host cell. Fusion proteins are the most common targets for neutralizing antibodies and serve a vital role as vaccine immunogens to elicit a protective immune response. To develop an understanding of SARS-CoV-2 antibody-mediated neutralization, one ... WebA virus must use its host-cell processes to replicate. The viral replication cycle can produce dramatic biochemical and structural changes in the host cell, which may cause cell damage. These changes, called cytopathic effects, can change cell functions or even destroy the cell. share sale agreement nz
