Q
Q: A patient develops an allergic reaction after exposure to pollen. Which type of immune response is primarily involved?
Solution:
Allergic reactions are primarily mediated by humoral immunity, specifically IgE antibodies.
Steps: 5
Show Steps
Step 1: Understand that allergic reactions occur when the immune system overreacts to a substance, like pollen.
Step 2: Identify that the immune system has different types of responses, including humoral immunity and cell-mediated immunity.
Step 3: Recognize that humoral immunity involves the production of antibodies by B cells.
Step 4: Learn that in allergic reactions, a specific type of antibody called IgE is produced.
Step 5: Conclude that the primary immune response involved in allergic reactions, such as the one to pollen, is mediated by IgE antibodies.
