(hyoo-mur-al) The type of immunity that fights bacteria and viruses in body fluids with antibodies that circulate in blood plasma and lymph, fluids formerly called humors.

The branch of the immune system that relies primarily on antibodies.

Immunity from infection and disease that comes from the release of antibodies in the blood.

Antibody-mediated immune response. Humoral Immunity is brought about by Antibody Formation, resulting from Th2 Cells activating B-Lymphocytes, followed by Complement Activation.

Type of immune response that is mediated by antibodies. See Related Term(s): Antibody, Cell-Mediated Immunity

protection provided by antibodies (as opposed to cellular immunity) Also known as $quot;antibody-mediated immunity.”

protection against disease that involves the binding of antibodies (which are proteins in the blood and lymph made by the immune system) to antigens based on the ability of the antibody to recognize the antigen. After recognizing antigens, antibodies attach to them, and signal T cells to attack. Antibodies also stimulate the release of special chem [..]

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.

Immunoglobulin (serum antibodies) dependent defense system.

Immunity mediated by humoral antibodies.

(immunology) Immunity to infection due to antibodies, which circulate in the blood and lymph, and which are produced by B cells.

Immune defense in which antibodies are produced by B-lymphocytes and circulate as soluble proteins in blood in lymph (or humors0. This is in comparison to cell-medicated immunity in which the T-cells come in close proximity to their victim cells). Humoral immunity is acquired; antibodies are produced by B- cells only in response to specific antigen [..]
