Immunology is about how the body defends itself against external attacks from infectious agents like viruses, bacteria and parasites. When the immune cells react on the agent, antibodies are produced. Antibodies are proteins that have the ability to attach to certain places on the infectious agent, and this starts the defense reactions that destroy the infectious agents.
When antibodies are formed, the body will develop an immunological memory that makes it easier for the immune system to respond quickly if the same infection returns later on.
Sometimes the body targets its immune response to the body’s own tissue. Then an autoimmune reaction is caused, and a chronic inflammation often occurs.
