Immune modulation using peptides and other compositions
First Claim
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 having a phosphatidylcholine component entrapping the nitric oxide, wherein the composition is stable at room temperature.

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 such as thyrotropin-releasing hormone (TRH) and/or GnRH (gonadotropin-releasing hormone). 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 structures 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.
