autoimmunity(redirected from Autoimmune reaction)
Also found in: Dictionary, Thesaurus, Encyclopedia.
In immunology, the condition in which one's own tissues are subject to deleterious effects of actions of the immune system, as in autoallergy and in autoimmune disease; specific humoral or cell-mediated immune response against the body's own tissues. Synonym(s): autoallergy
autoimmunity/au·to·im·mu·ni·ty/ (-ĭ-mu´nĭ-te) a condition characterized by a specific humoral or cell-mediated immune response against the constituents of the body's own tissues (autoantigens); it may result in hypersensitivity reactions or, if severe, in autoimmune disease.
autoimmunityThe reaction of a host organism’s immune system to self-antigens as if they were foreign. It is characterised by T-cell activation, clonal expansion and antibody production against tissues, cells and antigens, which results in autoimmune disease.
autoimmunitySelf immunity Immunology The reaction of an organism's immune system to self antigens as if they were non-self or foreign; like alloimmunity, autoimmunity is characterized by the activation of T cells, clonal expansion, and antibody production. See Anti-nuclear antibodies, Anti-receptor antibodies, Clonal anergy, Superantigen.
immunology The condition in which one's own tissues are subject to deleterious effects of the immune system, as in autoallergy and in autoimmune disease; immune response against the body's own tissues.
autoimmunitya situation where the immunological defences of the body become sensitized to parts of the same body resulting in self-destruction in that area. In other words, ‘self ANTIGENS become mistaken for ‘foreign’ antigens, so setting up an IMMUNE RESPONSE. Such an occurrence is clearly dangerous and may be associated with ageing. An example is rheumatoid arthritis in humans.
A condition in which the body's immune system produces antibodies in response to its own tissues or blood components instead of foreign particles or microorganisms.
n abnormal immune response where the body attacks its own tissue constituents. Also called
acute immune disease.
acute immune disease.
In immunology, the condition in which one's own tissues are subject to deleterious effects of actions of the immune system.
a condition which may result in autoimmune disease.
