Abstract

The present technology aims at providing a novel type of drug for treating a subject suffering from an inflammatory disease. Specifically, the present technology provides polypeptides comprising at least four immunoglobulin single variable domains (ISVDs), characterized in that at least two ISVDs bind to IL-13 and at least two ISVDs binds to TSLP. The present technology also provides nucleic acids, vectors and compositions.
