Target Information
The cysteine proteinase inhibitor, known as chicken cystatin, is a phosphoprotein. As a type 2 cysteine protease inhibitor, cystatin is crucial for epithelial barrier function and immunomodulatory processes. It also enhances the activation and recruitment of eosinophils. In conditions like eosinophilic chronic rhinosinusitis (CRS) and allergic rhinitis, cystatins may play significant roles by interacting with type 2 cytokines, microbial antigens, and fibroblasts, as well as by inhibiting allergen-induced histamine release.
