TermDefinition
immunocompetent having a normal immune response
self-tolerance this cell distinguish self and non-self your protein that your body make is self and nonself is the other protein that is not your and will be targeted for destroy.
cortex The outer layer of the cerebrum (the cerebral cortex), composed of folded gray matter and playing an important role in consciousness.
medulla The medulla oblongata is located in the brainstem, anterior and partially inferior to the cerebellum. It is a cone-shaped neuronal mass responsible for autonomic functions ranging from vomiting to sneezing.
thymus-dependent zone Medical Definition of Thymus-dependent zone. 1. Mid cortical region of lymph node, area that is particularly depleted of T lymphocytes in thymectomised animals and is referred to as the thymus dependent area.
germinal centers are sites within secondary lymphoid organs where mature B lymphocytes proliferate, differentiate, and mutate their antibody genes
antibody protein produced as the result of introduction of an antigen; also called immunoglobulins; secreted from plasma cells
afferent conducting or conducted inward or toward something (for nerves, the central nervous system; for blood vessels, the organ supplied).The opposite of efferent
thymic hormones the thymic gland produces the hormones thymosin, which stimulate the production of the antibody and thymus can create T-lymphocytes
red pulp and white pulp within the spleen and make up the splenic pulp
palatine (of an official or feudal lord) having local authority that elsewhere belongs only to a sovereign
lingual relating to, near, or on the side toward the tongue.
peyer's patches any of the nodules of lymphatic cells that aggregate to form bundles or patches and occur usually only in the lowest portion (ileum) of the small intestine; they are named for the 17th-century Swiss anatomist Hans Conrad Peyer
precursor a substance from which another is formed, especially by metabolic reaction
immunesurveilliance is a theory that the immune system patrols the body not only to recognize and destroy invading pathogens but also host cells that become cancerous
humoral relating to the body fluids, especially with regard to immune responses involving antibodies in body fluids as distinct from cells
plasma cells also called plasma B cells, plasmocytes, plasmacytes, or effector B cells, are white blood cells that secrete large volumes of antibodies. They are transported by the blood plasma and the lymphatic system
memory cells are a B cell sub-type that are formed within germinal centers following primary infection and are important in generating an accelerated and more robust antibody-mediated immune response in the case of re-infection
equisite extremely beautiful and, typically, delicate
heavy chains one of the polypeptide chain which have the greater molecular weight
light chain is identical and have half of the molecule weight than heavy chain
secretory component The secretory component is a component of immunoglobulin A (IgA). Secretory component is a proteolytic cleavage product of the polymeric immunoglobulin receptor which remains associated with dimeric IgA in sero-mucus secretions.
chemotactict adjective form of chemotaxis
induce bring about or give rise to.
immunogenicity noun form of immunogenic
antigenic determinants specific areas or combining sites on the surface of cells membrane of an antigen; determine specificity
antigen foreign substance, usually protein, capable of stimulating an immune response
autoimmunity immunity to self-antigens; loss of self-tolerance
complement series of enzymes, normally inactive, circulating in the bloodstream that, when activated by an antigen-antibody reaction, participate in the inflammatory response
immunity development of protection of the body against agents that are foreign to it
immunocompetent cells those cells that can recognize and react with antigen; T and B lymphocytes
memory ability to respond to an antigenic challenge because of previous exposure to the antigen and development of a bank of specific immunocompetent cells to that antigen
specificity property of reacting with one antigen only; both the antigen and the T or B lymphocyte have surface receptors that allow them to recognize each other specifically
tolerance state of unresponsiveness developed to a specific, known antigen.
