Regulatory T Cells and the Control of the Allergic Response

الملخص EN

The study of immune regulation and tolerance has been traditionally associated with self/nonself-discrimination.

However, the finding that dominant tolerance, a model that puts in evidence the active role of regulatory T cells, can develop to nonself-antigens suggests that the imposition of tolerance can be context dependent.

This paper reviews the emerging field of acquired immune tolerance to non-self antigens, with an emphasis on the different subsets of induced regulatory T cells that appear to specialize in specific functional niches.

Such regulatory mechanisms are important in preventing the onset of allergic diseases in healthy individuals.

In addition, it may be possible to take advantage of these immune regulatory mechanisms for the induction of tolerance in cases where pathological immune responses are generated to allergens occurring in nature, but also to other immunogens such as biological drugs developed for medical therapies.
