Chapter 35 Assessment of Immune Function -Brunner & Suddarth

Terms in this set (55)

antibody
a (large) protein substance developed by the body in response to and interacting with a specific antigen
aka immunoglobulins, consist of two sub-units, each containing a light and a heavy peptide chain held together by a chemical link made up of disulfide bonds
antigen
substance that induces the production of antibodies
apoptosis
programmed cell death that results from the digestion of deoxyribonucleic acid by end nucleases
B cells
cells that are important for producing a humoral immune response

make up about 10% to 15% of lymphocytes in the blood
cellular immune response
the immune system's third line of defense, involving the attack of pathogens by T cells
complement
series of enzymatic proteins in the serum that, when activated, destroy bacteria and other cells
cytokines
generic term for nonantibody proteins that act as intercellular mediators, as in the generation of immune response. When activated by T-cells they attract and activate B cells, cytotoxic T cells, NK cells, macrophages, and other cells of the immune system
cytotoxic T cells
(killer T-cells)
lymphocytes that lyse cells infected with virus; also play a role in graft rejection
-attack the antigen directly by altering the cell membrane, causing cell lysis
helper T cells
lymphocytes that attack foreign invaders (antigens) directly
-secrete cytokines, which attract and activate B cells, cytotoxic T cells, NK cells, and macophages, and other immune cells
-contribute to the differentiation of null & NK cells
humoral immune response
the immune system's second line of defense; often termed the antibody response
immune response
the coordinated response of the components of the immune system to a foreign agent or organism
immune system
the collection of organs, cells, tissues, and molecules that mediate the immune response
immunity
the body's specific protective response to a foreign agent or organism; resistance to disease, specifically infectious diseases
immunoregulation
complex system of checks and balances that regulates or controls immune responses
memory cells
cells that are responsible for recognizing antigens from previous exposure and mounting an immune response
