Method of treating asthma or allergy by administering an IL-33 receptor antibody
View Patent ↗Provided herein are methods of modulating IL-33 activity, e.g., for the purpose of treating immune diseases and conditions, as well as methods of screening for compounds capable antagonizing IL-33 signaling.
1. A method of treating asthma or allergy, comprising inhibiting IL-33 signal transduction by administering to a subject in need thereof an effective amount of an antibody, or antigen binding fragment thereof, that specifically binds to a complex of ST2 (residues 19-556 of SEQ ID NO: 5) and IL-1 RAcP (residues 21-570 of SEQ ID NO: 2).
2. The method of claim 1 , wherein the antibody or fragment thereof does not bind to ST2 alone.
3. The method of claim 1 , wherein the antibody or fragment thereof is a humanized antibody or human antibody.
4. The method of claim 1 , wherein the antibody or fragment thereof is a fragment selected from the group consisting of a Fab, an Fv fragment, and an F(ab′)2 fragment.
5. A method of decreasing the count of eosinophils, comprising inhibiting IL-33 signal transduction by administering to a subject in need thereof an effective amount of an antibody, or antigen binding fragment thereof, that specifically binds to a complex of ST2 (residues 19-556 of SEQ ID NO: 5) and IL-1 RAcP (residues 21-570 of SEQ ID NO: 2).
6. The method of claim 5 , wherein the antibody or fragment thereof is a humanized antibody or human antibody.
7. The method of claim 5 , wherein the antibody or fragment thereof is a fragment selected from the group consisting of a Fab, an Fv fragment, and an F(ab′)2 fragment.
