The Acari Hypothesis suggests mites and ticks cause allergies by transferring problematic dietary molecules via pattern recognition receptors. These receptors, when interacting with human immune systems, trigger allergic reactions to these molecules.
Area of Science:
- Immunology
- Allergology
- Zoology
Background:
- Allergens are often molecular components of acarians (mites and ticks) or their food.
- The Acari Hypothesis proposes acarians as key players in allergy development.
Purpose of the Study:
- To explain the mechanism by which acarian-derived molecules become allergens.
- To elucidate the role of pattern recognition receptors in allergy pathogenesis.
Main Methods:
- Observational analysis of allergen composition.
- Inference based on the function of acarian digestive tract pattern recognition receptors.
- Review of evidence on host immune responses to acarian infestation.
Main Results:
- Pattern recognition receptors in acarians bind to dietary molecules problematic to them.
- These receptors can mediate the removal of problematic molecules by the acarian immune system.
- Interspecies operability allows these complexes to induce IgE production in humans, leading to allergic reactions.
Conclusions:
- Allergens are molecules that are problematic for acarians, as indicated by their selection by acarian pattern recognition receptors.
- Understanding the acarian-allergen relationship offers insights into host anti-acarian defenses.
- The Acari Hypothesis provides a framework for understanding allergy and acarian-host interactions.

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.

Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
