antibodies that are dissolved in blood, lymph and other body fluids bind the antigen and trigger a response to it

(Latin, umor = fluid) The production of antibodies.

Immunity associated with and characterized by antibodies that circulate in the blood.

Immunity conferred by circulating antibodies produced by B lymphocytes and plasma cells.

Secondary immune response involving B-lymphocytes (B-cells) that produce antibodies.

The ability of the immune system to produces antibodies against antigens. Humoral immunity is produced by B lymphocytes and their derivative, plasma cells. Plasma cells are the principal antibodies forming cells. The cells are scattered throughout the lymph nodes, other lymphatic tissue, and the bone marrow. When the B-lymphocyte make contact with an antigen they become activated, transform into plasma cells and make antibodies that react only with that antigen. (See Cellular Immunity)

(HUE-muh-rul ih-MYOO-neh-tee) Form of immunity whereby B cells and plasma cells produce antibodies to foreign agents (antigens) and stimulate T cells to attack them. These antibodies also stimulate the release of chemical mediators that enhance antigen destruction.

antibody-mediated immunity; one of the mechanisms, using antibodies found in the blood and other body fluids, that the body uses to fight off infections.

immunity based on the interaction of antibody with antigen. Involves both T and B cells and may be present in the company of cell-mediated immunity.

Immune reactions involving molecules secreted into the bloodstream; humoral mediators label bloodborne substances for estruction and removal by other components of the immune system.

a form of immunity where antigens stimulate antibodies which are circulating in the blood.

An immune response brought about by antibodies which recognize antigens on cancer cells.

antibody-mediated defense; resides ultimately in the B lymphocytes and is mediated by the antibodies produced by B cells

part of the immune system that provides immunity against disease-causing organisms in body fluids. The main functional unit of humoral immunity is an antibody.

A type of immunity in which B-cells transform to plasma cells producing antibodies against foreign agents ( antigens) after being stimulated by T-cells.

An immune response carried out by antibodies circulating in the blood.

The immunity that is the result of antibody production by B cells. Compare with 'cell-mediated immunity.'

Immunity provided by antibodies released by sensitized B cells and their plasma cell progeny. Also called antibody-mediated immunity.

immunity mediated by antibodies.

protection provided by antibodies (as opposed to cellular immunity) Also known as "antibody-mediated immunity."

Related Topic"This refers to immunity to infection created by proteins termed antibodies, often referred to as "B" cells..."

the branch of the immune system in which antibodies are produced in response to a foreign antigen.

see antibody-mediated immunity.

Immunity in which antibodies play the predominant role.

Immunity that results from the activity of antibodies in blood and lymphoid tissue.

Immunoglobulin (serum antibodies) dependent defense system.

Immune protection provided by soluble factors such as antibodies, which circulate in the body's fluids or "humors", primarily serum and lymph.

Humoral immunity is the immediate response to an antigen which triggers antibody production. This is opposed to cell-mediated immunity, which involves white blood cells and is a delayed response to an antigen.

Any immune reaction that can be transferred with immune serum is termed humoral immunity (as opposed to cell-mediated immunity). In general, this term refers to resistance that results from the presence of specific antibody.

Antibodies secreted by mature B cells involved in defending the body against pathogens and tumors

Immune response characterized by the formation of antibodies, which are proteins secreted by specific cells (B cells and plasma cells). The antibodies decrease the growth and/or harmful effects of a microorganism or its products.

The branch of the immune system that relies primarily on antibodies.See also Antibodies; Cell-Mediated Immunity.

acquired immunity in which circulating antibodies (immunoglobulins) play a key role.

Production of antibodies to defend the body.

The branch of the immune system that relies primarily upon antibodies. See also "Cellular Immunity."

Immunity which is due to circulating antibodies in the blood and other bodily fluids.

the antibody-producing branch of the immune system.
