Verified step by step guidance

Understand the context of type I allergic reactions, which are immediate hypersensitivity reactions involving the immune system.

Recognize that in type I allergic reactions, the immune system produces a specific type of antibody known as Immunoglobulin E (IgE).

Learn that these IgE antibodies bind to receptors on the surface of certain immune cells, which are crucial for the allergic response.

Identify the specific immune cells involved in type I allergic reactions. These are mast cells and basophils, which have high-affinity receptors for IgE.

Conclude that when IgE antibodies bind to mast cells, it leads to the release of histamine and other mediators, causing the symptoms of an allergic reaction.
