How do antibodies kill viruses?

Best Answers

Technically viruses are not alive, therefore they cannot be killed. Also see: Are viruses living or non-living organisms? read more

Therefore viruses and antibodies are crosslinked into a large complex (see video below), which is less motile and can not infect cells anymore. Marking: Antibodies can not only interact with the antigen, but also through the constant domain with immune cells. read more

When our bodies come under attack from a viral infection they launch a sophisticated defence known as 'the immune response'. Our immune system is designed to recognise the cells that make up our bodies and repel any foreign invaders such as viruses. read more

Many enveloped viruses are lysed when antiviral antibodies and serum complement disrupt membranes. Non-neutralizing antibodies are also produced after viral infection. Such antibodies bind specifically to virus particles, but do not neutralize infectivity. They may enhance infectivity because antibodies can interact with receptors on macrophages. The entire virus-antibody complex is brought into the cell by endocytosis. read more
