The present invention relates to target binding members (e.g., antibodies) that bind a specified epitope of human IL-25. The invention also relates to target binding members (e.g., antibodies) that comprise one or more humanized antibody VL domain sequences and bind IL-25. The invention further relates to compositions comprising target binding members (e.g., antibodies) that bind IL-25, methods of producing such target binding members, and uses of such target binding members for the treatment or prevention of diseases and conditions (e.g., asthma, inflammatory bowel disease).
