Topical nitric oxide releasing nanoparticles for reversing androgenetic alopecia

Overview

Topical Nitric Oxide Releasing Nanoparticles (NO-np) present a groundbreaking approach to treating androgenetic alopecia (AGA). These nanoparticles release nitric oxide (NO) upon hydration, which enhances capillary dilation, increases blood flow, and promotes cell proliferation and angiogenesis, all crucial for hair follicle nourishment and regeneration. They also synergize with other treatments, such as Minoxidil, to improve efficacy and bioavailability. With a low-cost production process, NO-np has significant potential for widespread application in hair loss treatments.

Technical specifications

NO-np is based on hydrolyzing tetramethyl orthosilicate, glucose, and sodium nitrite. Upon hydration, they release NO over several hours, which acts as an intercellular signaling molecule promoting cell proliferation and angiogenesis. Key features include:

• Capillary dilation: Improves blood flow to nourish hair follicles.
• Cell proliferation: Stimulates hair follicle regeneration through the regulation of factors like β-catenin, VEGF, and MMP3.
• Anti-inflammatory effects: Reduces inflammation by downregulating cytokines such as IL-6 and TGF-β1.
• Synergy with Minoxidil: Enhances the effectiveness of concurrent topical treatments.

Technology readiness level

Currently at Technology Readiness Level 3, NO-np has shown promising preclinical results in mouse models. Further validation involves six months of testing on male and female mice with AGA, with and without Minoxidil. This study will include assessments of hair regrowth, follicle size, scalp blood flow, and biomarker expression levels to confirm efficacy and inform future clinical studies.
