(The ISYS Project) Any substance capable of generating such a response is called an antigen, or immunogen. Antigens are not the foreign microorganisms and tissues themselves; they are substances --- such as toxins or enzymes --- in the microorganisms or tissues that the immune system considers foreign.

- Treatment of disease by the administration of substances which produce a biological reaction in the organism. It includes the use of sera, antitoxins, vaccines, cells, tissues, and organs.(From Dorland, 28th ed).reatment to stimulate or restore the ability of the immune system to fight infection and disease. Also used to lessen side effects that may be caused by some cancer treatments. Also known as immunotherapy, biotherapy, or biological response modifier (BRM) therapy.

- Pathogens have markers on them known as antigens, which antibodies find and bind to. The binding of antigens to antibodies sparks the immune response. This is a complex interaction of immune tissues and cells that work to defend against invading organisms and fight infection.accines are small amounts of microbes or antigens administered to stimulate the immune system to produce memory cells against a specific disease. Memory cells are so effective that a person’s immune system may fight off an infection before any symptoms can occur.

AntibodyâMediated (Humoral) Immunity (AMI) The products of plasma cells are antibodies. An antibody is a specialized protein substance produced by the host cells in response to an antigen in the host's tissues. Antibodies are capable of reacting specifically with the antigen that provoked their production. Antibodies are often referred to as immunoglobulins.

Adaptive immune system The adaptive system response destroys invading pathogens and any toxic molecules they produce. Sometimes the adaptive system is unable to distinguish foreign molecules, the effects of this may be hayfever, asthma or any other allergies. Antigens are any substances that elicit the adaptive immune response.The cells that carry out the adaptive immune response are white blood cells known as lymphocytes.daptive immunity creates immunological memory after an initial response to a specific pathogen, leads to an enhanced response to subsequent encounters with that pathogen. This process of acquired immunity is the basis of vaccination.

immune response (ĭ-myo͞on′). A response of the body to a foreign substance, called an antigen, especially a microorganism or virus that causes disease. The immune response involves the action of white blood cells called lymphocytes, which work to deactivate foreign antigens, often by stimulating the production of antibodies.

- Antibodies are large Y-shaped protein molecules created by the immune system to identify and neutralize foreign objects and pathogens, such as bacteria, viruses, fungi, parasites, and toxins. Also known as immunoglobulin, antibodies are manufactured by white blood cells called B-lymphocytes, or B-cells.

- Each vaccine contains a killed or weakened form of the organism (usually a virus or bacterium) that causes a particular disease. Even though the organism in the vaccine has been altered so that it won’t make you ill, the part of the organism that stimulates your immune system to respond (the antigen) is still present.n antigen specifically induces the production of antibodies which can bind to it and neutralise it. While most vaccines work by inducing B lymphocytes to produce antibodies (see below), activation of T-cells — another type of immune system cell that helps protect against disease — is also important for some vaccines.

- An antigen is defined as a substance that reacts with antibody molecules and antigen receptors on lymphocytes. An immunogen is an antigen that is recognized by the body as non-self and stimulates an adaptive immune response. For simplicity, both antigens and immunogens are usually referred to as antigens.

Circulatory System Organs, tissues, cells, and cell products work together to respond to dangerous organisms (like viruses or bacteria) and substances that may enter the body from the environment. 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.2  Examples of the anatomic system include the mucous membranes and the skin.here 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. 2  Examples of the anatomic system include the mucous membranes and the skin.

Lymphocytes T cells. T cells develop from liver or bone marrow stem cells that mature in the thymus. These cells play a major role in cell mediated immunity. T cells contain proteins called T-cell receptors that populate the cell membrane. These receptors are capable of recognizing various types of antigens.

immunity The foreign substance, usually a protein, is called an antigen, that is, one that generates the production of an antagonist. The most common response to the antigen is the production of antibody. The antigen--antibody reaction is an essential component of the overall immune response. A second type of activity, cellular response, is also an essential component.

- Biological response modifiers (BRMs) are substances that modify immune responses.They can be both endogenous (produced naturally within the body) and exogenous (as pharmaceutical drugs), and they can either enhance an immune response or suppress it.Some of these substances arouse the body's response to an infection, and others can keep the response from becoming excessive.iological response modifiers (BRMs) are substances that modify immune responses.

Antigen antigen. Any substance that can stimulate an immune response in the body and can react with the products of that response, that is, with specific antibodies or specifically sensitized T lymphocytes, or both. Antigens include bacteria, foreign substance (e.g. dust mite, grass, pollen of trees), toxins and viruses.. an antigen present on human erythrocytes that is exposed by treatment with neuraminidase or contact with certain bacteria. see CD a. T-dependent antigen one that requires the presence of helper T cells to stimulate antibody production by B cells; most antigens are T-dependent.

Immune response The inflammatory response (inflammation) occurs when tissues are injured by bacteria, trauma, toxins, heat, or any other cause. The damaged cells release chemicals including histamine, bradykinin, and prostaglandins. These chemicals cause blood vessels to leak fluid into the tissues, causing swelling.

Antibody and antigen When an antigen enters the body, it stimulates the immune system to produce antibodies. (The immune system is the body's natural defense system.) The antibodies attach, or bind, themselves to the antigen and inactivate it. Every healthy adult's body has small amounts of thousands of different antibodies.Each one is highly specialized to recognize just one kind of foreign substance.mmune response: The production of antibodies in response to foreign substances in the body. Immunity: The condition of being able to resist the effects of a particular disease. Immunization: The process of making a person able to resist the effects of specific foreign antigens.
