Figure 1: Expression of inflammasome components and interleukin (IL)-1β in normal and alopecia areata-affected scalp tissues.

(a) Paraffin-embedded normal scalp skin and alopecia areata lesions were immunohistochemically stained with anti-NLRP3, ASC, caspase-1 and IL-1β. (b) Skin sections from normal and spontaneous AA of C3H/HeJ mice were immunohistochemically stained with anti-NLRP3, ASC and IL-1β. Bars = 100 μm.
