Определение antigens в Английский Язык Английский Язык словарь
A foreign substance that can stimulate an immune response when introduced into the body
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
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
Any substance capable of stimulating an immune response, usually a protein or large carbohydrate that is foreign to the body
Foreign or "nonself" substances that, when introduced the body, activate the immune system
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
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 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
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
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
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
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
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
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
