December 2008 in “Journal of Dermatological Case Reports” In this study, R-CSLM showed promise in evaluating hair shaft diseases by providing high-quality images of hair structures, although further development is necessary for follicle and perifollicular area analysis.
This study identified specific lncRNAs and mRNAs differentially expressed in miniaturized follicles compared to normal follicles in patients with androgenetic alopecia, with AL136131.3 potentially inhibiting hair growth and accelerating follicle transition to catagen through effects on glycolysis-related genes.
January 2026 in “Dermatologic Therapy” In this prospective study, ritlecitinib effectively reduced hair loss in patients with severe alopecia areata, with 43.3% of participants achieving a 20 or lower SALT score by week 24, and showed a good midterm safety profile.
July 2025 in “Journal of Investigative Dermatology” AI-09 is safe, effective, and reduces wrinkles for up to 6 months.
April 2024 in “bioRxiv (Cold Spring Harbor Laboratory)” In this study, researchers identified a gene regulatory network in Arabidopsis that controls root hair growth under low-temperature conditions, revealing specific transcription factors and downstream targets that contribute to this growth response despite overall plant development being halted.
February 2025 in “Biomolecules” This study found that activation of RORA significantly promotes the level of autophagy in rat hair follicle stem cells, suggesting a potential target for research on hair follicle development and treatments for conditions like alopecia.
