The improvement of FEV-1 reversibility is a cumulative result of 4 factors
• decreased IL-4, enhances inhibition of IgE production.• decreased IL-5, enhances inhibition of eosinophil
maturation in the stem cell, chemo taxis, and prolonged life span.
• increased IFN- enhances isotype switching of immunoglobuline production in favor of IgG subclass instead of IgE.
• increased IL-2 enhances the affinity maturation and differentiation of B cells giving rise to the generation of B memory cells and antibody secreting plasma cells producing IgG.

Conclusion
Immunotherapy in asthmatic children results in elevation of IFN- and IL-2, diminish IL-4 and IL-5.
Addition of inhaled corticosteroid to immunotherapy results in marked attenuation of IL-5 correlates with greater elevation of IL-2 and play an important role in the modulation of immune response resulting in the improvement of FEV-1 reversibility.

1. The primary mechanism of action is a shift in the balance of Th-1 and Th-2 cytokine expression in the allergen-challenged site.
2. Allergen IT is highly form of treatment of IgE mediated diseases.
3. Highly effective for allergic rhinitis and hypersensitivity to wasp and bee venom.
4. Consideration for primary use in asthma is still controversial in regards the potential development of adverse event.
