Drug Toxicity: Allergic Reactions

84
Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial...

Transgenic Plants

8.9K
Recombinant DNA technology called transgenesis is often used to add a foreign gene or remove a detrimental gene from an organism. Such genetically modified organisms are called transgenic organisms.
The first-ever transgenic plant was a tobacco plant developed in 1983 that showed resistance against the tobacco mosaic virus. Since then, many transgenic plants have been developed and commercialized for improving the agricultural, ornamental, and horticultural value of a crop plant. Transgenic...

Area of Science:

  • Agricultural biotechnology
  • Food safety
  • Genetics

Background:

  • Genetically modified foods are entering the market, offering improved crop characteristics and consumer benefits.
  • Ensuring the safety of agricultural biotechnology products, particularly novel proteins introduced into food, is crucial before commercialization.

Purpose of the Study:

  • To outline the safety assessment process for novel proteins in genetically modified foods.
  • To evaluate the potential allergenicity of proteins introduced through agricultural biotechnology.

Main Methods:

  • Assessing the source of introduced genes.
  • Analyzing sequence homology to known allergens.
  • Evaluating protein expression levels, functional classification, and physicochemical properties (e.g., heat and digestive stability).
  • Testing reactivity with IgE from allergic individuals.

Main Results:

  • Most allergens are proteins, but only a small fraction of food proteins are typically allergenic.
  • Current agricultural biotechnology products do not involve gene transfer from known allergenic sources.
  • The described criteria provide confidence in the low allergenic potential of introduced proteins.

Conclusions:

  • Comprehensive safety assessments, focusing on protein allergenicity, are essential for genetically modified foods.
  • Established criteria effectively evaluate the allergenic potential of novel proteins in agricultural biotechnology.
  • Current products demonstrate a low risk of allergenicity, ensuring consumer safety.
