## Abstract

Provided are isolated polyspecific antibodies directed to a unique epitope in the chemokine eotaxin 2. The antibodies bind additional CCR3-binding chemokines. Further provided are methods for using of the antibodies for attenuating the migration of various cells and for treating fibrotic diseases, autoimmune inflammatory disorders, monocyte related disorders or allergic atopic disorders.

## Claims

### Claim 1

A nucleic acid molecule encoding a humanized antibody that binds to at least two CCR3-binding chemokines wherein said nucleic acid molecule comprises the sequence denoted by SEQ ID NO: 1 and SEQ ID NO: 2.

### Claim 2 (depends on 1)

An expression vector comprising the nucleic acid molecule of claim 1.

### Claim 3 (depends on 1)

A host cell comprising the nucleic acid molecule of claim 1.
