Mimicking Antigen-Driven Asthma in Rodent Models-How Close Can We Get?

Area of Science:

• Immunology
• Pulmonology
• Pharmacology

Background:

• Asthma is a complex, heterogeneous respiratory disease with increasing global prevalence.
• Characterized by airway inflammation, mucus hypersecretion, and bronchial hyperresponsiveness.
• Asthma endotypes are broadly classified as Type 2 or non-Type 2, influencing disease presentation.

Purpose of the Study:

• To review current Type 2 vs. non-Type 2 rodent models of asthma.
• To assess methods for simulating asthma development, exacerbations, and inflammation quantification.
• To discuss genetically modified and humanized models for deeper mechanistic insights.

Main Methods:

• Review of existing literature on rodent asthma models.
• Assessment of techniques for simulating disease and measuring allergic airway inflammation.
• Evaluation of genetically modified and humanized animal models.

Main Results:

• Overview of acute and chronic Type 2 and non-Type 2 rodent asthma models.
• Detailed assessment of methods for simulating disease and quantifying inflammatory responses.
• Discussion of advanced models, including genetically modified and humanized systems.

Conclusions:

• Rodent models are crucial for understanding asthma pathomechanisms.
• Genetically modified and humanized models offer deeper insights into asthma development.
• Careful consideration of species differences is vital for clinical translation of research findings.
