Abstract

Claims (16)

1. A method of treating lupus nephritis in a human subject in need thereof, the method comprising:

(a) measuring elevated levels of soluble TNF-like weak inducer of apoptosis (TWEAK) in a biological sample from the human subject in need thereof as compared to a control, wherein the control is a biological sample from a healthy subject, a cohort of healthy subjects, or is a baseline value from the human subject in need thereof and

(b) administering a therapeutically effective amount of a TWEAK/TWEAK-R blocking agent to the human subject in need thereof.

2. The method of claim 1 , wherein the TWEAK/TWEAK-R blocking agent is selected from the group consisting of an anti-TWEAK antibody or antigen-binding fragment thereof, an extracellular region of a TWEAK receptor, wherein the extracellular region consists of amino acids 28-X1 of SEQ ID NO:2, wherein X1 is an amino acid selected from the group consisting of amino acids 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, and 80 of SEQ ID NO:2, and an anti-fibroblast growth factor-inducible 14 (Fn14 blocking antibody or antigen-binding fragment thereof.

3. The method of claim 1 , wherein the TWEAK/TWEAK-R blocking agent is an anti-TWEAK antibody or antigen-binding fragment thereof or an anti-Fn14 blocking antibody or antigen-binding fragment thereof, and wherein the antibody or antigen-binding fragment thereof is selected from the group consisting of a single chain antibody, Fab fragment, F(ab′)2 fragment, Fd fragment, Fv fragment, and dAb fragment.

4. The method of claim 1 , wherein the human subject exhibits decreased proteinuria as a result of administering the TWEAK/TWEAK-R blocking agent.

5. The method of claim 1 , wherein the biological sample is a urine sample, a serum sample, a plasma sample, or a cerebrospinal fluid sample.

6. The method of claim 1 , wherein the biological sample is a urine sample.

7. The method of claim 1 , wherein soluble TWEAK is measured by immunoassay or dipstick immunoassay.

8. The method of claim 1 , wherein soluble TWEAK is measured by ELISA or sandwich ELISA.

9. The method of claim 1 , wherein the TWEAK/TWEAK-R blocking agent is an anti-TWEAK antibody or antigen-binding fragment thereof.

10. The method of claim 1 , wherein the TWEAK/TWEAK-R blocking agent is an anti-Fn14 blocking antibody or antigen-binding fragment thereof.

11. The method of claim 5 , wherein the TWEAK/TWEAK-R blocking agent is an anti-TWEAK antibody or antigen-binding fragment thereof.

12. The method of claim 5 , wherein the TWEAK/TWEAK-R blocking agent is an anti-Fn14 blocking antibody or antigen-binding fragment thereof.

13. The method of claim 6 , wherein the TWEAK/TWEAK-R blocking agent is an anti-TWEAK antibody or antigen-binding fragment thereof.

14. The method of claim 6 , wherein the TWEAK/TWEAK-R blocking agent is an anti-Fn14 blocking antibody or antigen-binding fragment thereof.
