Therapy for radiation-induced lung injury
View Patent ↗Methods are disclosed for therapy of radiation-induced lung injury and other lung diseases using R-spondin1.
1. A method for treating a subject with a radiation-induced lung injury comprising administering to the subject after exposure to radiation R-spondin1 in an amount effective to treat a radiation-induced lung injury occurring at least 3 months after exposure to radiation.
2. The method of claim 1 , wherein the subject is a patient who is receiving radiation therapy, a nuclear power plant worker, a nuclear warfare personnel, or a subject who is exposed to elevated levels of radiation due to a nuclear accident, war or terrorist attack.
3. The method of claim 1 , wherein the radiation-induced lung injury occurs at least 6 months after exposure to radiation.
4. The method of claim 1 , wherein R-spondin1 is administered to the subject using a viral vector that expresses R-spondin1 protein.
5. The method of claim 4 , wherein the viral vector is a recombinant adenovirus vector.
6. The method of claim 1 , wherein R-spondin1 is administered to the subject as a purified recombinant protein.
7. The method of claim 1 , wherein R-spondin1 is a human R-spondin1.
8. The method of claim 1 , wherein administration of R-spondin1 to the subject inhibits one or more of radiation-induced pulmonary inflammation, deposition of collagen in the lungs, plural infusion of fluid, and lung fibrosis.
9. The method of claim 1 , wherein the subject is a human.
