What is the connection between protein and immunity?
The basic link between protein and immunity is that the body recognizes infectious agents called pathogens by their specific proteins. These proteins are called antigens and can be produced by viruses, bacteria and cancer cells. Antibodies are a class of proteins that are produced by the body that can bind with antigens on the surface of bacteria to give one example. When this happens, the bacteria are marked to be destroyed by white blood cells. Another important connection between protein and immunity is that the body can obtain long -term immunity by memorizing antigens associated with the specific causes of infectious disease.
Immunity usually refers to what is called active natural immunity. This occurs when the body is naturally exposed to pathogen, such as the one that caused the cold of another person. Active artificial immunity concerns the process of vaccination in which a pathogenic antigen is introduced into the body.
allowed to develop effective vaccines. Vaccines work by introducing antigens to create an immune response. They are comfortable because they stimulate the immune response in the body, but do not create symptoms of the disease. This is achieved by methods that may include adjusting microorganism or using viral proteins without the introduction of a real virus.
The body can use the connection between protein and immunity to provide long -term immunity against the pathogens she previously encountered. When he first encounters an infectious pathogen, it takes some time to create effective antibodies during which a foreign organism had time to cause symptoms of a disease or disease. After this so -called primary response, some cells retain the ability to produce specific antibodies. When the antigen is more represented, cells called memory B cells are quickly distributed into a rapid response. The body is already ill because the antibodies are produced MnOhem faster and more of them are produced.
white blood cells illustrate one somewhat complex connection between protein and immunity. The most important cells of the immune system are the type of white blood cells called lymphocytes that have two main groups called T and B cells. T cells may first attack a foreign cell as bacteria by recognizing specific antigens of bacteria and then release their own proteins that eventually cause bacteria. Through the separate process B cells eventually cause antibodies. Antibodies bind to antigens on bacteria, which are then destroyed by phagocytes, another type of white blood cells.
