Which class of antibodies is primarily involved in allergic reactions?

Step 1: Understand what antibodies are. Antibodies are proteins made by the immune system to help fight off infections and other foreign substances.
Step 2: Learn about the different classes of antibodies. There are five main classes: IgA, IgD, IgE, IgG, and IgM.
Step 3: Focus on IgE. This class of antibodies is specifically linked to allergic reactions.
Step 4: Recognize that IgE antibodies react to allergens, which are substances that can cause allergies, like pollen or pet dander.
Step 5: Remember that IgE is also involved in responses to parasitic infections, but its primary role in this context is in allergies.
