Antibody Structure01:10

Antibody Structure

51.5K
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...

Allergic Reactions: Anaphylaxis

275
Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin,...

Hypersensitivities01:30

Hypersensitivities

7.2K
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...

Area of Science:

  • Biotechnology
  • Immunology
  • Synthetic Biology

Background:

  • Allergic disorders are increasing globally, necessitating better diagnostic tools.
  • Identifying specific allergens is crucial for managing patient exposure and improving quality of life.
  • Current methods for allergy diagnosis can be limited in sensitivity or scope.

Purpose of the Study:

  • To develop a novel mammalian cell-based system for profiling allergies.
  • To engineer a sensitive and dynamic assay for detecting histamine release from human basophils.
  • To provide a tool for personalized allergy diagnostics in the modern medical landscape.

Main Methods:

  • Utilized synthetic biology principles to design a cell-based allergy profiler.
  • Engineered a synthetic signaling cascade within mammalian cells.
  • Integrated histamine release from whole-blood-derived human basophils to reporter protein production.

Main Results:

  • The allergy profiler accurately scores allergen-triggered histamine release.
  • The system demonstrates high sensitivity and a wide dynamic range for histamine detection.
  • The assay allows for both rapid results and long-term storage of output.

Conclusions:

  • The developed cell-based profiler offers a sensitive and versatile method for allergy diagnostics.
  • This synthetic biology approach supports personalized medicine by providing detailed allergy profiles.
  • The non-intrusive nature of the test enhances patient care and allergen management strategies.
