Allergenic protein-induced type I hypersensitivity models: a review.

Area of Science:

• Immunology
• Allergology

Background:

• Type I hypersensitivity impacts about one-third of the global population.
• Its complex pathophysiology necessitates animal models for novel therapeutic strategies.
• Common conditions include asthma, food allergy, and anaphylactic shock.

Purpose of the Study:

• To review methods for designing animal models of type I hypersensitivity.
• To compare shrimp tropomyosin-induced models with ovalbumin-induced models.

Main Methods:

• Searched PubMed and Web of Science databases.
• Reviewed various methods for common allergenic protein-induced type I hypersensitivity models.
• Summarized passive anaphylaxis, active systemic anaphylaxis/anaphylaxis shock, food allergy, asthma, and IgE-mediated cell models.

Main Results:

• Various models exist for type I hypersensitivity, including passive anaphylaxis, active systemic anaphylaxis/anaphylaxis shock, food allergy, and asthma models.
• Shrimp tropomyosin-induced models offer specific insights compared to ovalbumin-induced models.
• Model selection requires careful consideration of protocol variables, species, and strains.

Conclusions:

• Animal models are essential for advancing the understanding and treatment of type I hypersensitivity.
• Comparing different allergen-induced models, like shrimp tropomyosin versus ovalbumin, aids in selecting appropriate research tools.
• Accurate reflection of human clinical symptoms is key in animal model selection.
