Summary
Allergic immune responses involve an imbalance of CD4+ T cells. Hyposensitization therapy can restore the balance between allergen-specific T helper 2 (Th2) cells and regulatory T (Treg) cells, promoting tolerance.
Area of Science:
- Immunology
- Allergy Research
- T cell Differentiation
Context:
- Allergic immune responses are characterized by an imbalance in CD4+ lymphocytes.
- Atopic allergy shows elevated type 2 helper T lymphocytes (Th2 cells) compared to regulatory T lymphocytes (Treg cells).
Purpose:
- To investigate the role of T lymphocyte imbalance in allergic immune responses.
- To understand the immunologic tolerance mechanism in healthy subjects.
Summary:
- Healthy individuals exhibit a higher ratio of Treg cells to Th2 cells, indicating tolerance to allergens.
- Allergen-specific Treg cells are crucial for generating immunologic tolerance.
- Hyposensitization therapy has been found to correct the Th2/Treg cell imbalance.
Impact:
- Restoring the balance of Th2 and Treg cells can normalize immune responses to allergens.
- This research provides insights into potential therapeutic strategies for allergic diseases.

Hypersensitivities
Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...

Drug Toxicity: Allergic Reactions
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
Hypersensitivity Reactions: Immune-Complex Reactions
Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
Allergic Drug Reactions
Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing numerous...
Hypersensitivity Reactions: Delayed Hypersensitivity Reactions
Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
Desensitization and Tachyphylaxis
Tachyphylaxis is described as a rapid decrease in response to a drug after repeated or continuous administration of the same drug dose. It is a phenomenon where the body becomes less responsive to a particular substance or intervention over time, requiring higher doses or stronger interventions to achieve the same effect. It results from adaptive changes in the body's receptors, signaling pathways, or physiological processes that occur in response to prolonged exposure to a stimulus.
