antigen

listen to the pronunciation of antigen
Englisch - Englisch
A substance that induces an immune response, usually foreign
any foreign substance that triggers an immune response
A substance that when introduced into the body stimulates the production of an antibody
A foreign substance (almost always a protein) that, when introduced into the body, stimulates an immune response
A substance that when introduced into the body stimulates the production of an antibody Antigens include toxins, bacteria, and foreign blood cells
any substance that stimulates the immune system to produce antibodies Antigens are often foreign substances such as invading bacteria or viruses (See also immunogen )
A foreign substance that elicits the production of antibodies
A substance recognized by the immune system as foreign or toxic which elicits an immune response Antigens include bacteria, viruses, and chemicals If the antigen is part of the same organism, it is called a self antigen An antigen is any protein that can be recognized as foreign and that will generate an immune response
Any foreign substance that causes the body’s natural antibodies to form
A protein "recognized" by the body as being foreign; it results in the production of specific antibodies directed against it
An antigen is a substance that helps the production of antibodies. a substance that makes the body produce antibodies (antigène, from anti- + -gène (from -genes )). Foreign substance in the body that induces an immune response. The antigen stimulates lymphocytes to produce antibodies or to attack the antigen directly (see antibody;immunity). Virtually any large foreign molecule can act as an antigen, including those of bacteria, viruses, parasites, foods, venoms, blood components, and cells and tissues of various species, including other humans. Sites on the antigen's surface fit and bind to receptor molecules on the lymphocytes' surface, stimulating the latter to multiply and initiate an immune response that neutralizes or destroys the antigen
substance that promotes the production of antibodies
a foreign substance in the body such as protein, bacteria, virus, pollen, and other material Antigens stimulate the body to produce antibodies, which then fight them
Foreign protein that stimulates an immune response by a specific antibody
Substances such as toxins, enzymes or foreign molecules that cause an immune response by antibodies; a substance that, when introduced into the body, induces an immune response by a specific antibody
A protein or other molecule that can elicit an immune response; the antibody protein that is produced binds to the antigen
Foreign substances (e g bacteria or viruses) in the body that are capable of causing disease The presence of antigens in the body triggers an immune response, usually the production of antibodies
Any substance that when introduced into the body (such as the protein coat of an invading pathogen) causes the formation of antibodies Ag is also found on tissue and blood cells, and in body fluids Measurement of antigen can help determine whether a particular disease will become active
a substance that can trigger an immune response causing the production of antibodies as part of the body's defense against infection and disease
Substance, usually a protein, that when introduced into the body causes the body to make an antibody, usually specific to the antigen
A substance that can elicit the formation of an antibody when introduced into the body
A foreign molecule or substance, such as a transplant, that triggers an immune response This response may be the production of antibodies
A foreign macromolecule that does not belong to the host organism and that elicits an immune response
Anything introduced into the body that is seen as foreign An antigen stimulates the immune system into producing cells that attack it Hepatocellular carcinoma: Cancer of the liver A malignant tumour arisisng in the liver In most cases, it occurs as a complication following cirrhosis
any substance (as a toxin or enzyme) that stimulates the production of antibodies
An antigen is any substance that the body regards as foreign and which therefore triggers an immune response; antigens are usually proteins associated with bacteria and viruses
An antigen is a substance that can trigger an immune response, resulting in production of an antibody as part of the body's defense against infection and disease Many antigens are foreign proteins (those not found naturally in the body) An allergen is a special type of antigen which causes an IgE antibody response
A foreign substance that can trigger an immune system response, resulting in production of an antibody as part of the body's defense against disease
{i} foreign substance which stimulates the production of antibodies when introduced into a living organism

antigenicity
The ability, or degree of ability, to react with the products of an immune response
broad antigen
In the testing of cell surface antigens, a serological specificity that is poor or broad relative to other specificities and can be defined as 2 or more split antigens.(Example: HLA-B51 and HLA-B52 are split antigens of the HLA-B5 broad antigen)Okimoto K, Juji T, Ishiba S, Maruyama H, Tohyama H, Kosaka K. HLA--Bw54 (Bw22-J, J-1) antigen in juvenile onset diabetes mellitus in Japan. Tissue Antigens 1978 11(5): 418–22 pmid=694905
group specific antigen
The genetic material that codes for the structural protein of a retrovirus
histocompatibility antigen
any of the human leukocyte antigens (HLAs) which are the determinants of histocompatibility
split antigen
In the testing of cell surface antigens, an antigen that has a more refined or specific cell surface reaction relative to a broad antigen.(Example: HLA-B51 and HLA-B52 are split antigens of HLA-B5)Okimoto K, Juji T, Ishiba S, Maruyama H, Tohyama H, Kosaka K. HLA--Bw54 (Bw22-J, J-1) antigen in juvenile onset diabetes mellitus in Japan. Tissue Antigens 1978 11(5): 418–22 pmid=694905
histocompatibility antigen
Any of the genetically determined antigens on the surface of cell membranes that identify a cell as self or nonself and that determine whether a tissue graft will be accepted by an organ transplant recipient
antigenic
Antigenic means allergenic or having the properties of an antigen
antigenic
being able to induce an antibody response
antigenic
Pertaining to the degree to which a substance that acts as an antigen in an individual
antigenic
of or relating to antigens
antigenic
{s} of antigens
antigenicity
{i} production of antibodies
antigenicity
{1, The ability, or degree of ability, to induce an immune response
antigens
A foreign substance that can stimulate an immune response when introduced into the body
antigens
Substances that cause an immune response in the body The body "sees" the antigens as harmful or foreign To fight them, the body produces antibodies, which attack and try to eliminate the antigens
antigens
Substances, such as proteins, that can trigger an immune response, for example, the production of an antibody The antigens of the ABO blood group system are examples
antigens
Any substance capable of stimulating an immune response, usually a protein or large carbohydrate that is foreign to the body
antigens
Foreign or "nonself" substances that, when introduced the body, activate the immune system
antigens
a foreign invader that stimulates a response from the body's immune system
antigens
Foreign substances in the body that are capable of causing disease The presence of antigens in the body triggers an immune response, usually the production of antibodies Antigens may be soluble substances, such as toxins and foreign proteins, or particulate, such as bacteria and tissue cells; however only the portion of the protein of polysaccharide molecule known as the antigenic determinant combines with antibody or a specific receptor on a lymphocyte
antigens
substances capable of inducing an immune response
antigens
plural of antigen
antigens

histocompatibility antigen
Any of the genetically determined antigens on the surface of cell membranes that serve to identify a cell as self or nonself. These antigens determine whether a tissue graft will be accepted by an organ transplant recipient
