WebSuch tolerance may be induced by exposing an animal to the antigen at a very early stage of life, prior to maturation of the immune system, or, in adults, by exposing the animal to repeated low doses of a weak protein antigen (low-zone tolerance), or to a large amount of an antigen (high-zone tolerance). WebDec 24, 2016 · Low dosage of TD antigens may induce T cell tolerance – the low-zone tolerance, while high dosage of TD antigens may induce both T- and B-cell tolerance – the high-zone tolerance.
