Adoptive immunotherapy

Patent Granted Adoptive T-cell therapy is a form of passive immunization by the transfusion of T-cells. They are found in blood and tissue and usually activate when they find foreign pathogens. Specifically they activate when the T-cell's surface receptors encounter other cells that display small parts of foreign proteins on their surface antigens. These can be either infected cells, or specialised immune cells known as antigen presenting cells (APCs).
