Which type of blood cells is primarily responsible for allergic reaction control?

Eosinophils are primarily responsible for controlling allergic reactions and combating parasitic infections. These white blood cells are a type of granulocyte and have a unique ability to respond to allergens by releasing various substances, including enzymes and cytokines. During an allergic reaction, eosinophils migrate to sites of inflammation and play a crucial role in mediating and regulating the immune response associated with allergies.

Their granules contain proteins that can damage parasitic organisms and contribute to the inflammation process seen in allergies, making them vital for the body’s defense mechanisms. While other types of blood cells, such as basophils, also play a role in allergic reactions by releasing histamine, eosinophils are particularly significant in managing the later stages of allergic responses and inflammation. Therefore, recognizing the role of eosinophils is essential in understanding the immune response to allergens.
