Abstract

In addition to the involvement of proteinases on the induction of itch in atopic dermatitis, the mechanisms were also investigated. This study demonstrated that serine proteinases, such as tryptase, and proteinase-activated receptor-2 (PAR_2) played an important role on the induction of itch in atopic dermatitis. In addition to keratinocytes, PAR_2 is expressed on primary afferents. Thus, PAR_2-expressed primary afferent is important on the transmission of itch in atopic dermatitis.
