IL-1α antibody inhibits dose-dependent exacerbation of eosinophilic inflammation by crude house-dust-mite antigen in the conjunctiva of an atopic keratoconjunctivitis mouse model.

The house-dust-mite antigen increased eosinophilic infiltration and Il13 mRNA expression in the conjunctiva of an atopic keratoconjunctivitis mouse model in a dose-dependent manner. These inflammatory alterations were partially alleviated by eyelid injection of anti-IL-1α antibody. These findings indicate that IL-1α-induced IL-13 production constitutes a major exacerbating factor for house-dust-mite antigen-induced atopic keratoconjunctivitis.
