To discuss:
The role of the epitope in the antigenicity of a molecule.
Introduction:
For all living organisms, there is a challenge for surviving by defeating the entire pathogenic organism. The human body kills the pathogen or eliminates the foreign particles by an organized system called the lymphatic system. The lymphatic system or immune system consists of a group of cells or immune cells that inhabit all the organs of the body. The lymphatic system includes lymphatic organs and a group of lymphatic tissues that are involved in the immune system.
An antigen is any substance (molecule) that stimulates an immune response. Free molecules such as toxins, venom, and food substances act as antigens. Other antigens include components of bacterial cell wall and plasma membrane.

- The concept that antibody responses to a second immunization or infection with a pathogen is faster, but did not explain how that quick response is achieved. Using references to specific proteins, explain why that secondary response can be faster than a primary response. Explain how they work and how they are related to the phenomenon.arrow_forwardIn order for T cells to bind to an antigen _____________ must occur.arrow_forwardHow vaccines, in general, help the body develop immunity against various diseases.
