Cancer Immunotherapy Immunity and Tumors 1890s Coley treats patients with bacterial extracts 19501960s Burnet and Thomas Immunesurveillance Hypothesis Major function of the immune system is to recognize and destroy arising malignantly transformed cells. Tumor antigens. Immune system’s reaction to tumor antigens. How tumors . evade. . the. immune system. Immunologic approaches to treatment of cancer. Cancers . arise. from . the. . uncontrolled. . Ch.16. What is Immunity?. Immunity is resistance to infection after a foreign antigen has penetrated the first line of defense,. Immunity is achieved naturally, by having the disease or the artificial immunization. . Chapter 22. Functions of the Immune System. Destroy pathogens (organisms that cause disease). Detect and kill abnormal cells such as cancerous cells. Remove dead cells and debris from the body. Pathogens. Present before exposure to pathogens. Present at birth. Non-antigen specific. Consists of:. Skin… barrier for microbes and viruses. Compromised by abrasion or laceration. Sebacious. sweat is acidic (pH 3-5)… prevents colonization of bacteria. Presented by [NAME]. Overview of cognitive/emotional symptoms. Affects more than half (50%) of patients with malignant brain tumors. Causes. From the tumor itself: symptoms based on tumor size/location. Chapter 16: Innate (nonspecific) Immunity. Some terms:. Susceptibility. : Lack of immunity to a disease.. Immunity. : Ability to ward off disease.. . . immunity. : Defenses against any pathogen.. Veterinary assisting program. Responsibilities . The immune system is responsible for protecting the animal from potentially harmful organisms attempting to invade.. It is a VERY complicated system. It must be able to recognize substances that are foreign to the body by recognizing what is naturally . Begin . Dermoid. cyst. Mucocele. Hemangioma. Lymphangioma. Malignant . rabdomyosarcoma. Benign tumors of the orbit . can develop from infancy and grow rapidly or slowly. It can be superficial and easily identifiable by external presentation, palpation and x – rays or CT scan . Immune Responses. Applications of the Immune Response. A. Vaccination – the practice of deliberately stimulating the immune system in order to protect individuals against a disease. 1. Edward Jenner developed the first official smallpox . The term Immunity has traditionally referred to the resistance exhibited by the host towards injury caused by microorganism and their product.. However, protection against infectious disease is only one of many consequences of immune response, which in its entirety is concerned with the reaction of the body against any foreign antigen.. of certain substances in . the blood and lymph stream. . These . substances are known as antibodies. . This immunity is inborn. . . Antigens. , the foreign substances that attack the body, stimulate the production of antibodies. . The resistance that an individual acquires during life by recognising and selectively eliminating specific foreign molecules is known as acquired immunity..
