Disorders of the Immune System An overactive immune system. If you are born with certain genes, your immune system may react to substances in the environment that are normally harmless. These substances are called allergens. Having an allergic reaction is the most common example of an overactive immune system.hen your immune system doesn't work the way it should, it is called an immune system or immunodeficiency disorder. You may: Be born with a weak immune system. This is called primary immune deficiency.

Immune System Research Immune Tolerance. Tolerance is the prevention of an immune response against a particular antigen. For instance, the immune system is generally tolerant of self-antigens, so it does not usually attack the body's own cells, tissues, and organs. However, when tolerance is lost, disorders like autoimmune disease or food allergy may occur. Learn about the ways immune tolerance is maintained. Disorders of the Immune System

Immunodeficiency disorders Proteins and cells in the blood are also part of the immune system. The immune system helps protect the body from harmful substances called antigens. Examples of antigens include bacteria, viruses, toxins, cancer cells, and foreign blood or tissues from another person or species.

Immune system The immune system is a system of many biological structures and processes within an organism that protects against disease. To function properly, an immune system must detect a wide variety of agents, known as pathogens, from viruses to parasitic worms, and distinguish them from the organism's own healthy tissue.he principle behind vaccination (also called immunization) is to introduce an antigen from a pathogen in order to stimulate the immune system and develop specific immunity against that particular pathogen without causing disease associated with that organism.

The immune system and cancer The immune system protects the body against illness and infection caused by bacteria, viruses, fungi or parasites. It is really a collection of reactions and responses that the body makes to damaged cells or infection. cells react against invading bacteria or viruses by making proteins called antibodies. The antibody made is different for each different type of germ (bug). The antibody locks onto the surface of the invading bacteria or virus.

Organ Donation and Transplantation - What is transplant rejection? The immune system may attack and reject the transplant kidney, but in a different way than in acute rejection. Chronic rejection is often caused by antibodies in the blood against the transplanted kidney, and investigation of someone with chronic rejection should include a check of the blood for these antibodies.

- In a broad sense, your immune system helps you fight disease. There are two parts to the immune system: Non-specific immunity + Specific immunity. Nonspecific immunity Consist … s of your skin, saliva, mucus, etc.Skin is the most important part in keeping diseases from entering your body. Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system. Antibodies are proteins produced by the body to neutralize or … destroy toxins or disease-carrying organisms.

- Transplant rejection can be classified in three ways, depending on how soon after transplantation it occurs: Acute rejection – ‘Acute’ means short-term, and refers to an illness with a rapid onset. Acute rejection generally occurs during the first few months after transplantation. Acute rejection can be either T cell mediated or antibody mediated. Hyperacute rejection – Occurs within a few minutes after the transplant. This kind of rejection can happen when antibodies against the transplanted organ are already present in the body (a type of antibody-mediated rejection).

What Are Immune Deficiency Disorders? Most of the time, the immune system protects the body from germs and other threats. But sometimes it gets off track and reacts slowly. This low activity is called immune deficiency and it makes you less able to fight off infections.It can result from medications or illness.Or it may be present from birth -- a genetic disorder known as primary immune deficiency. Examples include: Severe combined immune deficiency (SCID). A genetic condition causing severe impairment in multiple areas of the immune system.t can result from medications or illness.

Circulatory System There are three types of response systems in the immune system: the anatomic response, the inflammatory response, and the immune response. 1  The anatomic response physically prevents threatening substances from entering your body. Examples of the anatomic system include the mucous membranes and the skin.

How Does The Immune System Fight Disease? A healthy and responsive immune system fights the disease causing pathogens and micro organisms with the help of special cells and tissues. Immune system is made up of a system of cells and organs. Its primary function is to build resistance in the body and fight off diseases and infections. It detects the various disease causing agents and protects the body against their attack. The bone marrow, spleen, lymph nodes and thymus are some important organs of the immune system.

Diagram of the Human Immune System (Infographic) The immune system protects the body against disease or other potentially damaging foreign bodies. When functioning properly, the immune system identifies and attacks a variety of threats, including viruses, bacteria and parasites, while distinguishing them from the body’s own healthy tissue.The Lymphatic system consists of bone marrow, spleen, thymus and lymph nodes.he spleen is the largest lymphatic organ in the body contains white blood cells that fight infection or disease. The thymus is where T-cells mature. T-cells help destroy infected or cancerous cells. Lymph nodes produce and store cells that fight infection and disease.

Stress, Illness and the Immune System The main types of immune cells are white blood cells. There are two types of white blood cells – lymphocytes and phagocytes. When we’re stressed, the immune system’s ability to fight off antigens is reduced. That is why we are more susceptible to infections.hort term suppression of the immune system is not dangerous. However, chronic suppression leaves the body vulnerable to infection and disease. A current example of this is AIDS-Acquired immune deficiency syndrome. Here the immune system is suppressed leaving the vulnerable to illness.

Function and Role of Immune System The body’s defense against various microorganisms that cause disease and illness is the immune system. The immune system attacks these disease causing organisms through a sequence of steps referred to as the immune response.The immune system is composed of a number of cells, tissues and organs that work in association and attacks the disease causing microorganisms and protect the human body.The cells of the immune system are the leukocytes or the white blood cells.he circulation of the leukocytes in the body takes place between the lymph nodes and the various organs through the blood vessels and lymphatic vessels. Hence, the functioning of the immune system occurs in a coordinated manner, thereby, monitoring the body against disease causing germs and microorganisms.

Liver Transplantation The new liver may also be rejected. Rejection is a normal reaction of the body to a foreign object or tissue. When a new liver is transplanted into a recipient's body, the immune system reacts to what it perceives as a threat and attacks the new organ, not realizing that the transplanted liver is beneficial.
