autoimmunity

The 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.

autoimmunity

Self 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.

autoimmunity

a 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.

Autoimmunity

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.
