(Greek: self, same, spontaneous; directed from within)
2. An antibody that reacts against normal substances present in the organism producing it and is present in autoimmune diseases.
3. An antibody directed against a self antigen, i.e., against a normal tissue constituent.
An antibody (immunoglobulin) formed in response to, and reacting against, one of the individual's own normal antigenic endogenous body constituents.
- In autoimmune diseases, such as type 1 diabetes, the immune system mistakenly manufactures aintibodies that target the body's tissues.
- Certain of these "autoantibodies" appear many years before overt symptoms of any disease, suggesting that screening for these molecules could be used to predict who is at risk of falling ill.
- Autoantibodies might also serve as guides to disease severity and progression and might even warn of risk for some nonimmune disorders.
- Screening for predictive autoantibodies could one day become routine, although a scarcity of preventive treatments currently stands in the way.
2. A "self antigen"; any tissue constituent that evokes an immune response to the host's tissues.
3. A type of antigen present in the tissues of an organism which causes the development of corresponding antibodies.
An antigen is a harmful substance that causes a person's body to produce antibodies to fight the body itself.
Antigens include toxins (poisons), bacteria, foreign blood cells, and the cells of transplanted organs.
2. The prevention of a severe illness caused by an overwhelming poisoning of the bloodstream by toxin-producing bacteria: Mark takes his vitamins on a daily basis to support his natural autoantisepsis which helps him to stay healthy.
2. An antitoxin produced by an individual that will inhibit the action of a toxin released from the tissues of that same individual.
2. A cessation or failure of the respiratory process (breathing) as a result of internal metabolic activities.
The term metabolism refers to the entire physical and chemical processes involved in the maintenance and reproduction of life in which nutrients are broken down to generate energy and to give simpler molecules (catabolism) which by themselves may be used to form more complex molecules (anabolism) and it also consists of all of the physical and chemical changes that occur in cells to allow growth and to maintain body functions as food is converted into the energy and the products needed to sustain life.
An autobiographer is someone who describes his many interesting experiences, some of which are possibly true.
2. Marked by writing about one's own experiences and life history.
An autobiography is a book that usually reveals nothing bad about its writer except his/her memory.
An autobiography is fiction written by someone who actually knows the facts.
