Allergens typically lead to which of the following immune responses?

Allergens typically provoke an overreaction of the immune response, leading to what is commonly known as an allergic reaction. This occurs when the immune system mistakenly identifies normally harmless substances, such as pollen, dust mites, or certain foods, as threats. The immune system responds to these allergens by producing specific antibodies, especially Immunoglobulin E (IgE), which triggers the release of various chemicals, including histamines, from mast cells and basophils. This response results in symptoms such as inflammation, itching, and other allergic responses.

The exaggerated immune response is a hallmark of allergic reactions, as the body fails to properly regulate its response to these harmless antigens. This overreaction can cause significant discomfort and distress, underscoring the unique aspect of allergic pathways compared to typical immune responses to pathogens.
