IL-1β and Allergy: Focusing on Its Role in Allergic Rhinitis

Figure 1

Possible cellular sources and effector cells of IL-1β following allergen challenge. The left side of the picture shows the possible source cells of IL-1β, and the thickness of the blue arrow suggests the primary and secondary relationship of the source; the purple arrow on the right side of the picture points to the possible effector cells of IL-1β; and the dashed arrows all suggest potential IL-1β related cells, but there is insufficient literature as a theoretical basis.
