Antibody Structure01:10

Antibody Structure

57.3K
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.

Antibodies consist of four polypeptide chains: two identical heavy...

Hypersensitivities

369
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...

Enzyme-Linked Immunosorbent Assay01:33

Enzyme-Linked Immunosorbent Assay

12.2K
In 1971, Peter Perlman and Eva Engvall developed an Enzyme-linked immunosorbent assay (ELISA or EIA). ELISA differs from western blot in that the assays are conducted in microtiter plates or in vivo rather than on an absorbent membrane.
There are many different types of ELISAs, but they all involve an antibody molecule whose constant region binds an enzyme, leaving the variable region free to bind its specific antigen.  Enzyme-substrate reaction allows the antigen to be visualized or...

Transcytosis of IgG01:15

Transcytosis of IgG

2.7K
Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...

Summary

Food allergy involves adverse immunologic responses to food, often IgE-mediated, leading to symptoms across multiple body systems and anaphylaxis. Effective management requires timely diagnosis and patient empowerment.

Area of Science:

  • Immunology
  • Allergology
  • Clinical Medicine

Background:

  • Food allergy is an adverse immunologic reaction to food.
  • Immunoglobulin E (IgE)-mediated food allergies can affect skin, GI, respiratory, and cardiovascular systems.
  • IgE-mediated food allergy is a primary cause of anaphylaxis, necessitating prompt diagnosis and treatment.

Purpose of the Study:

  • To provide a comprehensive overview of IgE-mediated food allergy.
  • To cover epidemiology, pathophysiology, diagnosis, and management strategies.
  • To highlight the importance of patient and caregiver empowerment in managing food allergies.

Main Methods:

  • Review of existing literature on IgE-mediated food allergy.
  • Discussion of diagnostic approaches including patient history, skin prick tests, serum-specific IgE, and oral food challenges.
  • Exploration of management strategies focused on risk reduction and patient empowerment.

Main Results:

  • IgE-mediated food allergy presents with diverse symptoms affecting multiple organ systems.
  • Accurate diagnosis relies on a combination of clinical history and specific tests.
  • Management aims to reduce reaction risks, alleviate anxiety, and enhance patient control.

Conclusions:

  • Understanding the epidemiology, pathophysiology, and diagnosis of IgE-mediated food allergy is crucial.
  • Effective management empowers patients and caregivers to control food allergy.
  • Timely and appropriate care is imperative for individuals with IgE-mediated food allergy.
