Abstract

Chimeric polypeptides encoded by a DNA sequence having a first DNA subsequence coding for a fragment of at least one of the .alpha.- and/or .beta.-chain of the human interleukin-5 receptor, and a second DNA subsequence coding for the constant domains of a heavy- or a light-chain of a human immunoglobulin, or a fragment thereof are useful in treating illnesses with demonstrated eosinophilia.
