Antibody Structure

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.

Allergic Drug Reactions

978
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...

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

453
Asthma is a chronic respiratory condition for which new therapeutic avenues, including anti-inflammatory drugs like mast cell stabilizers and anti-IgE treatments, continue to be developed.
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...

Antibody Structure and Classes

4.1K
Antibodies, also known as immunoglobulins, are produced by B cells in response to foreign substances, such as bacteria and viruses. These proteins are critical for recognizing and neutralizing these substances, protecting the body from potential harm.
The basic structure of an antibody consists of four protein chains: two identical heavy chains and two identical light chains. These chains are held together by disulfide bonds and other non-covalent interactions, forming a Y-shaped structure.

Antibody Actions

1.3K
Antibodies, or immunoglobulins, are critical players in the immune system's arsenal against invading pathogens. Produced by B cells and plasma cells, their primary role is to detect and bind to specific antigens, molecules found on the surface of pathogens like bacteria or viruses. Beyond antigen recognition, antibodies perform several vital functions that contribute to immune defense.
Neutralization
Antibodies can bind to pathogens, preventing them from infecting host cells. This process...

Area of Science:

  • Immunology
  • Allergy Research

Background:

  • Immunoglobulin E (IgE) drives allergic disease pathogenesis.
  • IgE binds to FcεRI on mast cells and basophils, mediating allergic reactions.

Purpose of the Study:

  • To review the critical role of IgE in allergic diseases.
  • To highlight IgE as a therapeutic and diagnostic target.

Main Methods:

  • Literature review of IgE's role in allergic pathogenesis.
  • Analysis of clinical applications and outcomes of anti-IgE therapies.

Main Results:

  • IgE triggers mast cell and basophil degranulation, releasing allergic mediators.
  • Anti-IgE therapies show efficacy in food allergy desensitization, asthma, and chronic urticaria.

Conclusions:

  • IgE is a pivotal factor in allergic disease development.
  • Targeting IgE is a validated strategy for managing allergic conditions.
