MONOCLONAL ANTIBODY AGAINST INTERLEUKIN-13 RECEPTOR ALPHA 1 (IL-13Ra1)

摘要

The present invention relates generally to antibodies that bind to the Interleukin-13 receptor a1 chain (IL-13Ra1) and antagonize IL-13 receptor-mediated signaling by IL-13 and/or IL-4. More particularly, the present invention provides humanized or human antibodies to mammalian and in particular IL-13Ra1. These antibodies have uses in the treatment or prevention of IL-13- and/or IL-4-mediated diseases or conditions. The present invention further contemplates a method of modulating IL-13- and/or IL-4-mediated diseases or conditions by the administration of the subject antibodies. The present invention further provides an assay system useful for identifying antibodies or other agents which modulate IL-13 and/or IL-4 signaling through an IL-13 receptor complex. Accordingly, a method of screening for modulators of IL-13Ra1/ligand interaction is also provided.
