This binding can sometimes kill the pathogen directly, but more usually the antibodies are recognised by other killing systems. Second, by binding to antigens on the pathogen, antibodies also signal other white blood cells known as phagocytic cells, which engulf and destroy the pathogen. Next up are the antibodies, these are special proteins that recognise a pathogen and bind to it. Popular. They can also consume and digest pathogens that have been destroyed by other white blood cells. The antibody recognizes a unique molecule of the pathogen, called an antigen. If antibodies confer immunity that is long-lasting, for example, people who have been infected may be protected until there is a viable vaccine. Antibodies kill bacteria by three different ways: 1)By binding to the surface of the pathogen they make it unable to enter or damage the host cell. Immunity against bacteria mainly relies on antibodies and can be seen through the primary and secondary immune response. Lymphocytes release antibodies that help to either destroy pathogens or make it easier for the phagocyte to do its job in digesting the pathogen. How antibodies work Antibodies are produced by B cells, also called B lymphocytes, which are made in bone marrow and found in the blood and lymph. The main cells of the immune system are lymphocytes known as B cells and T cells. But waning antibodies … An antibody (Ab), also known as an immunoglobulin (Ig), is a large, Y-shaped protein used by the immune system to identify and neutralize foreign objects such as pathogenic bacteria and viruses. Antibodies attach to an antigen and attract cells that will engulf and destroy the pathogen. Antibodies to one pathogen generally don’t protect against another pathogen except when two pathogens are very similar to each other, like cousins. These specific antibodies then allow for the rapid detection of subsequent infections with a particular pathogen, which allows for relatively quick defensive responses. The primary immune response is the immune response to the first infection from a specific pathogen, while the secondary immune response is the immune response to an infection by the same pathogen a second time. Antibodies have a distinctive Y shape, which is key to how they work. So, in short, antibodies can both neutralize a virus and mark it for destruction. The AIS uses the antigens to generate specific antibodies, which are used to tag the “foreigner” for destruction by specialized blood cells called lymphocytes. Once the antigen-specific antibodies are produced, they work with the rest of the immune system to destroy the pathogen and stop the disease. The immune system responds to antigens by producing cells that directly attack the pathogen, or by producing special proteins called antibodies. At the tips of antibodies are the unique sites where they bind with a matching site on antigens—and destroy them. Antibodies can also induce the innate immune response to destroy a pathogen, by activating phagocytes such as macrophages or neutrophils, which are attracted to antibody-bound cells.
