Abstract

The present invention generally relates to compositions and methods for topical or transdermal delivery for immune modulation. In some cases, the composition may include nitric oxide and/or peptides. The nitric oxide and/or peptide may be present within a first phase comprising a lecithin, such as phosphatidylcholine. In certain embodiments, the lecithin is present in liposomes, micelles, or other vesicles containing nitric oxide, peptides, or both. The composition can take the form of a gel, a cream, a lotion, an ointment, a solution, a solid “stick,” etc., that can be rubbed or sprayed onto the skin. Other aspects of the present invention are generally directed to methods of making or using such compositions, methods of promoting such compositions, kits including such compositions, or the like.

Claims

1. A method, comprising:

administering, to the skin of a subject to modulate the immune system of the subject, a composition comprising an effective amount of thyrotropin-releasing hormone (TRH) and molecular nitric oxide to modulate the immune system, and a carrier comprising lecithin entrapping the molecular nitric oxide, wherein the composition is stable at room temperature.

2. The method of claim 1, wherein the carrier further comprises polyenylphosphatidylcholine.

3. The method of claim 1, wherein the composition comprises a liquid crystal structure.

4. The method of claim 1, wherein the composition comprises no more than about 250 ppm of water by weight of the composition.

5. The method of claim 1, wherein the lecithin is present at at least about 0.25% by weight of the composition.

6. The method of claim 1, wherein the molecular nitric oxide is present at at least about 0.5% by weight of the composition without nitric oxide.

7. The method of claim 1, wherein the molecular nitric oxide is present within the composition as a gas.

8. The method of claim 1, wherein the molecular nitric oxide is bound by hydrogen bonds or van der Waals forces to the lecithin.

9. The method of claim 1, wherein the composition is a cream.

10. The method of claim 1, wherein the composition is a gel.

11. A method, comprising:

administering, to the skin of a subject to modulate the immune system of the subject, a composition comprising an effective amount of thyrotropin-releasing hormone (TRH) and molecular nitric oxide to modulate the immune system, and a carrier comprising lecithin entrapping the molecular nitric oxide, wherein the first phase comprises no more than about 250 ppm of water by weight of the composition.

12. The method of claim 11, wherein the carrier further comprises polyenylphosphatidylcholine.

13. The method of claim 11, wherein the composition comprises a liquid crystal structure.

14. The method of claim 11, wherein the composition is stable at room temperature.

15. The method of claim 11, wherein the lecithin is present at at least about 0.25% by weight of the composition.

16. The method of claim 11, wherein the molecular nitric oxide is present at at least about 0.5% by weight of the composition without nitric oxide.

17. The method of claim 11, wherein the molecular nitric oxide is present within the composition as a gas.

18. The method of claim 11, wherein the molecular nitric oxide is bound by hydrogen bonds or van der Waals forces to the lecithin.

19. The method of claim 11, wherein the composition is a cream.

20. The method of claim 11, wherein the composition is a gel.
