Abstract

Provided are methods of improving wound healing in a subject by administering a therapeutically effective amount of CD24. Also provided are pharmaceutical compositions which comprise CD24 being in a formulation with a surfactant and a pharmaceutically acceptable carrier.

Claims

1. A method of improving wound healing in a subject in need thereof, the method comprising topically administering to a wounded area of the subject a therapeutically effective amount of a CD24 protein, thereby improving the wound healing in the subject.

2. A method of improving wound healing in a subject in need thereof, the method comprising administering to the subject a therapeutically effective amount of a CD24 protein, thereby improving wound healing in the subject.

3. The method of claim 2, wherein said CD24 protein is injected to the subject.

4. The method of claim 2, wherein said CD24 protein is applied directly on a wounded area of the subject.

5. The method of claim 4, wherein said CD24 protein is applied by dropping a pharmaceutical composition comprising said CD24 protein on said wounded area of the subject.

6. The method of claim 2, wherein said CD24 protein is comprised in a medical dressing.

7. The method of claim 6, wherein said CD24 protein is soaked or impregnated in said medical dressing.

8. The method of claim 2, wherein said CD24 protein is comprised in a pharmaceutical composition.

9. The method of claim 8, wherein said CD24 protein is formulated with a surfactant in said pharmaceutical composition.

10. The method of claim 9, wherein said surfactant is an ionic surfactant.

11. The method of claim 9, wherein said surfactant is a non-ionic surfactant.

12. The method of claim 8, wherein a concentration of said CD24 protein in said pharmaceutical composition is between 1% to 10% (volume/volume) of a purified CD24 protein solution.

13. The method of claim 8, wherein said pharmaceutical composition is suitable for topical application.

14. The method of claim 13, wherein said pharmaceutical composition is comprised in an emulsion carrier, a cream, an ointment, an aqueous solution, a lotion or an aerosol.

15. The method of claim 2, wherein said CD24 protein is glycosylated.

16. The method of claim 2, wherein said CD24 protein comprises a native glycosylation pattern.

17. The method of claim 2, wherein said CD24 protein is non-glycosylated.

18. The method of claim 2, wherein said CD24 protein is soluble.

19. The method of claim 2, wherein said CD24 protein is non-soluble.

20. The method of claim 2, wherein said CD24 protein is conjugated to a lipid moiety.
