Abstract

Androgenic alopecia (AGA) is a prevalent progressive hair loss condition. The main therapeutic drug, minoxidil, is limited by its poor efficacy and side effects such as contact dermatitis and hypertrichosis. Nitric oxide (NO), an endothelial-derived relaxing factor, promotes angiogenesis and accelerates blood flow, enhancing nutrient supply similar to minoxidil. Accordingly, we utilized a poly(vinyl alcohol) film (PVA) loaded with hyaluronic acid (HA) liposomes to construct a multistage transdermal NO delivery system (PVA@HL/NONOate) for the treatment of AGA. The HA liposomes provided efficient NO loading and extended release, while the PVA film improved skin penetration and sustained NO release, increasing NO bioavailability. Low-concentration NO effectively enhanced hair follicle vitality and repaired blood vessels. Mechanistically, low-concentration NO could treat AGA mainly by regulating the HIF-1 signaling pathway to promote angiogenesis, reducing inflammation by downregulating the expression of TNFRSF9 and IL-6, repairing hair follicles by downregulating the expression of genes in the CXCL5-IL-17 inflammatory axis.

期刊介绍： ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times. The editors and staff of ACS Materials Letters actively participate in major scientific conferences and engage closely with readers and authors. The journal also maintains an active presence on social media to provide authors with greater visibility.
