What cells are released during times of allergy and asthma attacks?

Eosinophils play a critical role in the body’s immune response, particularly during allergic reactions and asthma attacks. These white blood cells are associated with the inflammatory response and are activated in the presence of allergens. When the body encounters a perceived threat, such as pollen or pet dander, eosinophils are recruited to the site of inflammation. They release various substances, including inflammatory mediators and toxins, to combat the allergens, but this can also lead to tissue damage and the symptoms associated with allergies and asthma, such as wheezing, coughing, and difficulty breathing.

This makes eosinophils particularly significant in the pathophysiology of asthma and allergy responses, as their increase in numbers can exacerbate the condition and contribute to the hyperreactivity of the airways. Therefore, understanding the function of eosinophils is crucial in addressing and managing allergic conditions and asthma effectively.
