specialized serum protein produced by B lymphocytes in response to an exposure to foreign proteins or modified natural proteins (both act as antigens) The antibodies produced specifically bind to the antigens that induced the immune response These are also called immunoglobulins or gamma globulins
a protein secreted by activated plasma cells, which evolve from B-cells, in response to stimulation by an antigen The antigen/antibody reaction forms the basis of humoral (Th2) immunity There are 5 types of antibodies: IgA, IgD, IgE, IgG and IgM
A protein found in the blood that is produced in response to foreign substances (e g bacteria or viruses) invading the body Antibodies protect the body from disease by binding to these organisms and destroying them
a special protein produced by the body’s immune system that recognizes and helps fight infectious agents and other foreign substances that invade the body
a special protein produced by the body's immune system that recognizes and helps fight infectious agents and other foreign substances that invade the body
A blood protein that is produced in response to and counteracts an antigen Antibodies are produced in disease states and help the body fight against the particular disease
A protein that is an immunoglobulin produced by a B cell in response to a specific antigen The antibody can bond with the antigen enabling an immune response Antibodies are the soldiers which protect us against bacteria and viruses that are free in the body (not inside cells) and parasitic infections
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
a special protein produced by the bodys immune system that recognizes and helps fight infectious agents and other foreign substances that invade the body
Molecules produced by B cells in response to specific proteins (antigens) carried by infected cells Antibodies are directed against specific infections and help fight the disease
A protein molecule produced by the immune system in response to a foreign body, such as a virus like HBV Antibodies can be produced in response to a vaccine or to a natural infection They circulate in the blood to protect against future infections
A substance produced by the body in response to an antigen that specifically reacts with the antigen to destroy, inhibit, or neutralize it The body produces antibodies as a defense against foreign substances Antibodies may be identified and measured to determine whether an individual has been infected by a pathogen
A protein (immunoglobulin) produced by the immune system of an organism in response to exposure to a foreign molecule (antigen) and characterized by its specific binding to a site of that molecule (antigenic determinant or epitope) [IUPAC Compendium]
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 Haemophilia: A hereditary blood disease where the blood fails to clot and abnormal bleeding occurs It is found only in males and is treated by injections of Factor VIII
any of a large variety of proteins normally present in the body or produced in response to an antigen which it neutralizes, thus producing an immune response
A protein produced by the body's immune system in response to a foreign substance (antigen) An antibody reacts specifically with the antigen that induced its formation and inactivates the antigen Our bodies fight off an infection by producing antibodies
a large Y shaped protein molecule made by B-cells of the immune system which very selectively binds to other specific protein molecules called antigens Specific antibodies combine with and inactivate specific viruses, while other specific antibodies mark invading bacteria and cancer cells for destruction by other cells of the immune system
Protein produced by humans and higher animals in response to the presence of another protein, termed an antigen The interaction of the antigen and the antibody can cause certain human health problems, like allergies or autoimmune diseases
An antibody is a protein (also called an immunoglobulin) that is manufactured by lymphocytes (a type of white blood cell) to neutralize an antigen or foreign protein Bacteria, viruses and other microorganisms commonly contain many antigens, as do pollens, dust mites, molds, foods, and other substances Although many types of antibodies are protective, inappropriate or excessive formation of antibodies may lead to illness When the body forms a type of antibody called IgE (immunoglobulin E), allergic rhinitis, asthma or eczema may result when the patient is again exposed to the substance which caused IgE antibody formation (allergen)
Antibodies are substances which a person's or an animal's body produces in their blood in order to destroy substances which carry disease. antibodies a substance produced by your body to fight disease. Molecule in the immune system that circulates in blood and lymph in response to invasion by an antigen. Antibodies are globulins formed in lymphoid tissues by B cells, whose receptors are specialized to bind to a specific antigen. These receptors are copied as antibodies that attack the target antigens by binding to them, either neutralizing them or triggering a complement reaction. Antibodies have widely varying binding sites, providing protection from a wide range of infectious agents and toxic substances. Antibodies derived from the blood serum of infected people or animals are often given in an antiserum for quick immunization against fast-acting toxins or microbes. In 1975 César Milstein and colleagues developed a process for producing specific antibodies in virtually limitless amounts; these monoclonal antibodies can deliver radiation or drugs directly to specific antigens. See also antitoxin; reticuloendothelial system
Normal blood serum apparently contains variousantibodies, and the introduction of toxins or of foreign cells also results in the development of their specific antibodies
