Specific Antigen Response

A specific antigen response is the body's targeted reaction to a particular foreign substance, such as bacteria, viruses, or toxins. When an antigen enters the body, the immune system recognizes it as foreign and activates specialized cells called lymphocytes. These cells produce antibodies tailored to bind precisely to that antigen, neutralizing or marking it for destruction. This specific response is essential for protecting against infections and creates immunity, so the body can quickly respond if it encounters the same antigen again in the future.
