Method for treating alopecia using ?c cytokine antagonist peptides
The granted patent US12030936B2 outlines a method for treating alopecia-related disorders through the administration of a specific composition. This composition includes a ?c cytokine antagonist peptide, which is derived from the ?c box D-helix regions of at least two interleukin (IL) proteins. The core sequence of this peptide is 11 amino acids long, specifically identified as SEQ ID NO: 1. The method aims to inhibit signaling by IL-2, IL-9, and/or IL-15, as well as to decrease circulating levels of IL-6 and/or IFN? in subjects experiencing alopecia or immune-mediated hair loss. The claims emphasize the peptide's role in ameliorating the severity of these conditions.
Further claims detail variations of the ?c cytokine antagonist peptide, including those that consist of the sequence of SEQ ID NO: 1, as well as peptides comprising 19 to 50 amino acids. The patent also describes potential modifications to the peptide, such as the addition of conjugates at various positions, which may include moieties like bovine serum albumin, antibodies, or Poly Ethylene Glycol. Additionally, the composition can be formulated for various delivery methods, including topical, oral, or parenteral routes, enhancing its applicability in treating alopecia-related disorders.
