Question

When a person with an allergic tendency is first exposed to a particular allergen,what cytokine is secreted by compatible helper T cells?​

Quizplus · Accepted Answer

IL-4 is secreted by compatible helper T-cells during the initial exposure to an allergen. It activates B-cells, leading to the production of IgE antibodies, which bind to mast cells and basophils. Upon re-exposure to the allergen, these cells are triggered to release histamine and other inflammatory molecules, resulting in an allergic response. IL-2, IL-3, IL-5, and IL-6 are also involved in the immune response, but are not specifically associated with the initial sensitization to an allergen.
