Research Abstract

ST2 protein is induced in the case of allergic diseases, such as bronchial asthma, in parallel with disease activity. Possible usage of the functional region of the ST2 protein as a novel drug against inflammatory reaction in allergic diseases, we clarified that core protein itself is able to suppress inflammation, and its glycosylation enhanced the inhibitory activity. We are now identifying minimum effective region of the ST2 protein.
