These phagocytes can engulf the unwanted cell and degrade it. Opsonization The antibody coats the surface of a bacterium green making it easier for phagocytic cells to attack the intruder. Complement proteins can kill the cell immediately or it again attracts phagocytes.
Crosstalk with receptor signaling In this case the antibodies can intercept the antigens preventing them from binding to host cells. Antibodies can also bind to receptors of abnormal cells or pathogens to shut down the communication and prevent further spreading of the infection. Virus neutralization Viruses have proteins on their surface which they need to enter the host cell in order to replicate and spread.
Antibodies can bind to viruses making them harmless. How do the antibodies destroy the substance produced by an antigen?

If an antibody molecule is treated with a proteolytic enzyme such as pepsin, the hinge region peptide bonds are broken producing 2 identical F ab fragments and one degraded Fc fragment. If an antibody molecule is treated with a proteolytic enzyme such as papain, the hinge region peptide bonds are broken producing 2 identical F ab fragments and one Fc fragment.
