The Role of Th17 Cells and IL-17 in Th2 Immune Responses of Allergic Conjunctivitis

Figure 1

In classical type I hypersensitivity reactions, activation of individual cells and immune molecules finally results in mast cell degranulation and eosinophil infiltration. Factors such as IL-3, IL-4, IL-5, and IL-13 produced by Th2 cells promote this process.
