Background:
Allergen-specific immunotherapy (AIT) is the only intervention capable of modifying the natural course of allergic diseases by inducing long-term immune tolerance. Its clinical efficacy depends on complex regulations of humoral and cellular immunity, yet objective assessment remains hindered by the absence of standardized biomarkers.
Summary:
This review summarizes recent advances in the immunological mechanisms of AIT and highlights emerging biomarkers-including allergen-specific immunoglobulin G4, regulatory T and B cells, and innate lymphoid cells-that may provide objective measures of efficacy and support individualized treatment strategies.
Key Messages:
(1) AIT uniquely modifies the natural history of allergic diseases; (2) current evaluation relies on subjective measures, highlighting the urgent need for standardized and clinically applicable biomarkers; (3) molecular markers and immune cell subsets offer promising tools for bridging mechanistic insights with clinical endpoints, supporting real-time monitoring and precision-guided optimization of AIT.

The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
01:10Antibody Structure
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
