Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs

1.7K
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...

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...

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.

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

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:

  • Food allergy research
  • Immunology
  • Vaccine development

Background:

  • Allergen-specific immunotherapy (AIT) is the only disease-modifying treatment for food allergies.
  • Oral immunotherapy (OIT) desensitizes patients but faces challenges with long schedules and adverse events.

Purpose of the Study:

  • To review state-of-the-art next-generation AIT vaccine technologies for food allergies.
  • To identify research gaps for future AIT development.

Main Methods:

  • Literature review of novel AIT platforms and vaccine candidates.
  • Analysis of preclinical and clinical trial data.
  • Application of a 'Cargo-Truck-Lubricant' analogy for AIT components.

Main Results:

  • Next-generation AIT platforms aim to increase immunogenicity and decrease allergenicity.
  • Focus has been primarily on peanut allergy, with other food allergies in early stages.
  • Vaccine candidates are under investigation in trials.

Conclusions:

  • Novel AIT vaccines hold promise for safer and more effective food allergy treatment.
  • Further optimization and clinical translation are needed.
  • Research gaps exist, particularly for non-peanut food allergies.
