Which cells produce and release leukotriene C4 and histamine during an allergic response in the eyes?

• A. Eosinophils
• B. Basophils
• C. Neutrophils
• D. Monocytes

Answer: (A)

Eosinophils play a significant role in the allergic response, particularly in the eyes. During an allergic reaction, these cells are activated and release various mediators, including leukotriene C4, which contributes to inflammation and the symptoms associated with allergies. Histamine, while primarily produced by basophils, is often associated with the broader context of an allergic response facilitated by eosinophils' actions. The activation of eosinophils is part of the immune response to allergens, where they migrate to the site of the allergen exposure and release inflammatory mediators. This release contributes to vasodilation, increased permeability of blood vessels, and the recruitment of other immune cells, amplifying the allergic response. Thus, eosinophils are critically linked to the production of leukotrienes and the promotion of inflammatory processes in allergic reactions affecting the eyes.
