Antigen

Antigens are molecules that can be recognized by the body's immune system and trigger an immune response. The very name “antigens” means those that oppose a gene. The term “agglutinins,” which is similar in origin, also implies exactly the opposite meaning. At the same time, agglutinogens cannot be opposed to antibodies (antibodies are substances that can react with antibodies). Antigens are unique to each individual, but they potentially exist in all living organisms. There are two types of mechanisms for the formation of antigens and one group of mechanisms that reveal them. The first group includes either biochemical, biophysical mechanisms leading to molecular and protein degradation of various compounds, or chemical reactions that occur quickly. The second group is formed by chemical reactions and processes that last for a longer time, when slow denaturation processes occur. The third group includes mechanical or physical interactions between anti
