Allergic Drug Reactions

1.3K
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...

Hypersensitivities01:30

Hypersensitivities

7.1K
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...

Antibody Structure

65.2K
Overview
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.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...

Antigens Involved in Adaptive Immunity01:26

Antigens Involved in Adaptive Immunity

1.3K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and...

Area of Science:

  • Immunology
  • Allergology
  • Molecular Biology

Background:

  • IgE-associated food allergy affects 3% of the population, impacting daily life and multiple organ systems.
  • Allergic sensitization to food allergens is observed early in childhood.
  • Pathogenesis involves IgE cross-linking, inflammatory mediator release, and T-cell/basophil/eosinophil activation.

Purpose of the Study:

  • To characterize molecular features of food allergens.
  • To develop chip-based assays for multiple allergens.
  • To understand cross-reactivity and identify key allergens for vaccine engineering.

Main Methods:

  • Characterization of molecular features of food allergens.
  • Development of chip-based assays for simultaneous detection of multiple allergens.
  • Analysis of cross-reactivity patterns among food allergens.

Main Results:

  • Chip-based assays provided insights into cross-reactivity among food allergens.
  • Identified specific disease-causing food allergens.
  • Enabled estimation of allergic reaction severity and types.

Conclusions:

  • Understanding food allergen structure is crucial for developing effective diagnostic tools.
  • Molecular insights facilitate the engineering of synthetic and recombinant vaccines for food allergies.
  • Further research into allergen structure can lead to improved therapeutic strategies.
