TSLP and atopic eczema: We found that, in patients with SAC and PAC, TSLP and its downstream molecules increased from mRNA levels and protein levels, but their expression was lower than that of VKC, which may be because the two types of allergic conjunctivitis are often associated with other histories of allergic diseases, such as allergic rhinitis, asthma, and atopic dermatitis, but the symptoms and signs of the patients were less than VKC.
