antibody
\an"ti*bod`y\ (?), n. (physiol. chem.) any of various bodies or substances in the blood which act in antagonism to harmful foreign bodies, as toxins or the bacteria producing the toxins. normal blood serum apparently contains variousantibodies, and the introduction of toxins or of foreign cells also results in the development of their specific antibodies.

antibody
[AN-tih-BAH-dee]
A type of protein made by plasma cells (a type of white blood cell) in response to an antigen (foreign substance). Each antibody can bind to only one specific antigen. The purpose of this binding is to help destroy the antigen. Antibodies can work in several ways, depending on the nature of the antigen. Some antibodies destroy antigens directly. Others make it easier for white blood cells to destroy the antigen.

antibody
protein in the blood that are generated in reaction to foreign proteins. antibodies selectively neutralize the foreign proteins, producing immunity to certain microorganisms or their toxins. Tests to determine if you are HIV positive look for HIV antibodies -- evidence that your body is attempting to fight the virus.

antibody (ab¸ immunoglobulin¸ ig)
an immunoglobulin protein secreted by activated plasma cells, which evolve from B-cells. Antibodies are present throughout the blood and tissues; they are produced in response to stimulation by foreign antigens as part of the body's defense against disease. Specific antibodies bind to and act upon specific antigens; the antigen/antibody reaction forms the basis of humoral (TH2) immunity. Neutralizing antibodies destroy or inactivate infectious agents,
while enhancing antibodies promote infection. There are 5 classes of immunoglobulins: IgA, IgD, IgE, IgG and IgM. See also immunoglobulin A-M.

Antibody
A protein secreted by cells of our immune system in response to infection. The antibody binds to an ‘enemy’ molecule, in this case, a specific part of the hepatitis C virus. This is meant to prevent the virus from infecting other cells or destroy it. As with other viral infections, the presence of antibodies does not necessarily mean a virus will be eliminated from the body. 2. A protein produced in the blood of vertebrates following exposure to an antigen. The antibody binds specifically to the antigen and thus stimulates its inactivation by other parts of the immune system. The major classes of antibody are immmunoglobulin A, or IgA, found predominantly in bodily secretions like saliva; IgM and IgG which are typically produced sequentially in response to microparasitic infections; and IgE which is often elevated in the response to helminth infections. Only IgG is able to cross the placenta to provide maternal immunity. The Good Guy

antibody
an infection-fighting protein molecule in blood or secretory fluids that tags, neutralizes, and helps destroy pathogenic microorganisms (e.g., bacteria, viruses) or toxins. Antibodies, known generally as immunoglobulins, are made and secreted by B lymphocytes in response to stimulation by antigens. Each specific antibody binds only to the specific antigen that stimulated its production. (See also immunoglobulin,binding antibody; enhancing antibody; functional antibody; neutralizing antibody.)

Antibody
Members of a class of proteins known as immunoglobins. Antibodies may tag, destroy and neutralize bacteria, viruses or other harmful toxins. Antibodies attack infected cells, making them vulnerable to attack by other elements of the immune system.

Antibody
Antibodies (also known as immunoglobulins) are proteins that are found in blood or other bodily fluids of vertebrates, and are used by the immune system to identify and neutralize foreign objects, such as bacteria and viruses. They are made of a few basic structural units called chains; each antibody has two large heavy chains and two small light chains. Antibodies are produced by a kind of white blood cell called a B cell. There are several different types of antibody heavy chain, and several different kinds of antibodies, which are grouped into different isotypes based on which heavy chain they possess. Five different antibody isotypes are known in mammals, which perform different roles, and help direct the appropriate immune response for each different type of foreign object they encounter.
