Contact Hypersensitivity as a Murine Model of Allergic Contact Dermatitis

[STATE OF NONALLERGIC HYPERSENSITIVITY UNDER THE EXPOSURE TO ADVERSE ENVIRONMENTAL FACTORS]
Abstract:
Now a number of allergopatologies is shown to be formed as non-allergic hypersensitivity. Research of this state is especially important when studying a question of formation of a condition of a chemical sensitization in response to the contact of a human body with chemical pollutants. For diagnostics of reactions of non-allergic hypersensitivity the test was developed for an assessment of activation of basophiles by specific allergens (the test of activation of basophiles by method of a flowing cytometry Flow Cast® (BD FACSCalibur)). It is possible to judge by activation on an expression of some receptors on a surface of these cages (CD63). Examination of a group of persons, having continuous contact with means of household chemicals was performed. In 54.5% of the examined persons the percent of CD63-of nonspecific activated cages was revealed to be at the level of 16-65% that gives the grounds to assume existence of a condition of not allergic hypersensitivity. Thus, the test of activation of basophiles by method of a flowing cytometry can be used for a differentiation of an IgE-dependent allergy from a condition of non-allergic hypersensitivity.
