Studysummary In this study, researchers identified a specific DNA aptamer, Ap.OR2AT4.17, that effectively prolonged hair growth and increased hair shaft elongation in organ-cultured human hair follicles by targeting the olfactory receptor OR2AT4. This finding suggests the aptamer's potential as a novel therapy for hair loss disorders.

The study investigates the use of a DNA aptamer, Ap.OR2AT4.17, to target the olfactory receptor OR2AT4 for promoting hair growth. Conducted on human hair follicles from 5 healthy male subjects, the research demonstrated that Ap.OR2AT4.17 effectively prolonged the anagen phase, increased hair shaft elongation, and enhanced the expression of antimicrobial peptides. The aptamer specifically binds to OR2AT4, leading to increased proliferation of hair matrix keratinocytes and upregulation of growth factors. These findings suggest that Ap.OR2AT4.17 could be a promising targeted therapy for hair loss disorders, with potential applications in regenerative and dermatological medicine.
