The total immunological reaction of an organism. The immune response includes antibody production, cell-mediated immunity, and complement activation.

A response by the immune system to seek and neutralise foreign substances. Inflammation A protective response in which the body reacts to infection, irritation or other injury, which serves to destroy, dilute, or block off both the cause of an injury and the injured tissue. The key feature being redness, warmth, swelling and pain. Insoluble Cannot be dissolved.

Response made by the immune system of a vertebrate when a foreign substance or microorganism enters its body.

The body’s defence against foreign objects or organisms, such as bacteria, viruses or transplanted organs or tissue.

a bodily response to an antigen that occurs when lymphocytes identify the antigenic molecule as foreign and induce the formation of antibodies and lymphocytes capable of reacting with it and rendering it harmless -- called also immune reaction

A highly specific defensive reaction of the body to invasion by a foreign substance or organism; consists of a primary response in which the invader is recognized as foreign, or "not-self," and eliminated and a secondary response to subsequent attacks by the same invader. Mediated by two types of lymphocytes B cells, which mature in the bone marrow and are responsible for antibody production, and T cells, which mature in the thymus and are responsible for cell-mediated immunity.

the stimulation of B and T lymphocytes.

The body's reaction to invasion by foreign substances; it involves inflammation of the affected part of the body.

the specific response to substances interpreted by the body as non-self.

the body's defense against antigens (substances such as bacteria and viruses) that the body recognizes as foreign and creates antibodies to destroy. The immune response can also be triggered by non-harmful substances. See allergy

the reaction of the body's immune system to foreign materials such as microbes which leads to their destruction or removal from the body.

the way in which the body defends itself against pathogens or foreign bodies.

the immune system's normal and expected reaction to any foreign matter in the body, including the transplanted kidney

An immune response to a vaccine occurs when the body's natural defence mechanism makes antibodies to the disease in question. This means that in the future, when the body comes in contact with the disease, the antibodies will recognise and be able to fight the infection.

The production of antibodies (humoral response) or particular types of cytotoxic lymphoid cells (cell-mediated response) on challenge with an antigen.

The activity of the immune system against a foreign body.

Interaction of an antigen with lymphocytes to induce the formation of antibodies.

The immune system's reaction against foreign substances.

The reaction of the body as a whole (not just the immune system, as in an immune reaction) to the presence of an antigen, which includes making antibodies, developing immunity, developing hypersensitivity to the antigen, and developing tolerance.

The bodys reaction to foreign antigens. This response may neutralize or eliminate the antigens and provide immunity.

a bodily defense reaction that recognizes an invading substance (an antigen: such as a virus or fungus or bacteria or transplanted organ) and produces antibodies specific against that antigen

an organism's reaction, mediated by components of the immune system, to an antigen

a normal response of the body to something it sees as abnormal

Defensive response of body to "foreign elements."

the body’s immune system response that defends against attacks from disease-causing agents. The body can produce two different immune responses – humoral immunity and cell-mediated immunity.

The immune response is the reaction of the body to substances that are foreign or treated as foreign. The response is in a variety of forms from the recognition of antigens in the body, the production of antibodies against the foreign substance and the response of lymphocytes (white blood cells, T cells and B cells).

A defensive action by the immune system to an infection or foreign material.

The body's natural defense system against infectious microbes-including disease-causing bacteria and viruses-as well as cancer cells within the body itself.

The body's natural defense against foreign substances that could be harmful, such as bacteria, viruses, or foreign tissue.

A collective and coordinated response to the introduction of foreign substances in an individual mediated by the cells and molecules of the immune system (1).

The reaction of the body to foreign substances like a transplanted organ. Jump to Top

A selective response mounted by the immune system of humans and animals in which specific antibodies and/or T-cells are produced as a defence against invading micro-organisms, transplanted tissue and other material recognized as foreign. There are two main types of immune response: the 'antibody-mediated (or humoral)' response, and the 'cellular' response (mediated by T-cells).

response of the immune system to the presence of antigen(s). Involves function of a variety of cell types, including T and B lymphocytes, macrophages and others.

The reaction of the body to anything from outside the body (foreign). This includes bacteria, viruses and foreign bodies. The immune response includes the manufacture of antibodies by B lymphocytes (helped by T lymphocytes). Foreign cells are also swallowed by cells called phagocytes.

The reactions of the immune system to foreign substances.

the reaction of the body to substances that are foreign or are interpreted as being foreign. See antigen and antibody.

The body's natural defense against bacterial assault, the immune response can also destroy alveolar bone in its attempt to destroy bacteria.

The body's reaction to a foreign substance.

the response which the body makes when invaded by a foreign substance or microbe.

The body's defense function that produces antibodies to foreign antigens. It is important in organ and tissue transplantation since the body is likely to reject new tissues.

the activity or response of the immune system against foreign substances.

The reaction of the immune system against foreign substances. When this reaction occurs against substances or tissues within the body, it is called an autoimmune reaction.

the response of the body's immune system to defend itself against pathogenic 'invasion'.

The reaction of the immune system to foreign substances.

The natural response to a foreign substance (eg. virus, bacteria). Responses involve many of the white blood cells, including T and B lymphocytes, macrophages, neutrophils, eosinophils and platelets.

The activity of the immune system against foreign substances (antigens).

The response by the body to "foreign" material (transplant or infection).

The body's reaction to infection.

Any defensive reaction to foreign material by the immune system.

The response of the immune system following exposure to a pathogen, vaccine or foreign protein

The activity of the various components of the immune system against antigens. The immune response involves B cells, T cells, Natural Killer cells and antigen processing cells, and may be specific to the antigen or nonspecific.

Collective and coordinated response by the molecules and cells of the immune system that result in the elimination of naturally acquired disease-causing agents. This response also can be triggered by vaccination leading to immune protection against specific diseases.

Immune system's reaction to antigens.

Response of the body to contact with an antigen that leads to the formation of antibodies and sensitized lymphocytes. Designed to render harmless the antigen and the pathogen producing it.

a physiological response produced in humans and higher animals, to defend the body against the introduction of foreign material. "Hay fever," for example, is the response sometimes produced by the human immune system to the inhalation of pollen. See antibody and antigen.

The reaction of the immune system against foreign substances. When the reaction occurs against the body's own cells or tissues, it is called an autoimmune reaction.
