Antigen-presenting cell vaccine
Antigen-presenting cell vaccine
An Antigen-presenting cell vaccine (pronunciation: an-ti-jen pre-sen-ting cell vak-seen) is a type of immunotherapy that uses the body's own immune system to fight diseases, particularly cancer.
Etymology
The term "Antigen-presenting cell vaccine" is derived from the function of the vaccine. An antigen is a substance that triggers an immune response, especially the production of antibodies. A cell is the smallest structural and functional unit of an organism. A vaccine is a biological preparation that provides active acquired immunity to a particular infectious disease.
Function
Antigen-presenting cell vaccines work by stimulating the body's immune system to recognize and destroy specific disease cells. The vaccine is made from antigen-presenting cells (APCs) that have been removed from the patient's blood, treated in the laboratory, and then returned to the patient. These APCs are then able to present the antigen to the immune system's T cells, stimulating an immune response.
