Title:
COMPOSITION FOR PREVENTING OR AMELIORATING LOSS OF HAIR AND GRAYING OF HAIR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2017/122668
Kind Code:
A1
Abstract:
The present invention provides a composition for preventing or ameliorating newly occurring loss of hair and a composition for preventing or ameliorating graying of hair. More specifically, the present invention provides a composition containing, as an active ingredient, an agent for stabilizing the expression of collagen XVII, preferably a collagen XVII decomposition inhibitor such as an ELANE inhibitor, or an agent for promoting the repairing of DNA or an agent for inhibiting the damage of DNA. When a composition containing, as an active ingredient, a collagen XVII decomposition inhibitor, such as an ELANE inhibitor, is administered to a mammal, an advantageous effect for preventing the loss of hair and the graying of hair can be produced. As the ELANE inhibitor, the collagen XVII decomposition inhibitor or the agent for promoting the repairing of DNA, a low-molecular-weight compound, a polypeptide, a protein, an antibody, or a nucleic acid drug such as an antisense oligonucleotide and siRNA can be used. Also provided is a method for screening for a substance that is effective for the prevention of the loss of hair and the graying of hair.
