mTOR signaling in hair follicle and hair diseases: recent progress

Area of Science:

• Cell Biology
• Dermatology
• Molecular Biology

Background:

• The mammalian target of rapamycin (mTOR) signaling pathway is a critical regulator of cellular processes, including proliferation and metabolism.
• This pathway plays significant roles in cell proliferation, apoptosis, inflammation, and various diseases.
• Emerging evidence highlights the mTOR pathway's influence on hair follicle circulation and the maintenance of hair follicle stem cells.

Purpose of the Study:

• To review the function of the mammalian target of rapamycin (mTOR) signaling pathway in hair follicles.
• To explore the role of mTOR signaling in hair diseases.
• To discuss the molecular mechanisms by which mTOR signaling regulates these processes.

Main Methods:

• Literature review of existing studies on mTOR signaling and hair biology.
• Analysis of research linking mTOR pathway activity to hair follicle function and stem cell maintenance.
• Examination of molecular mechanisms underlying mTOR's role in hair follicle health and disease.

Main Results:

• The mTOR signaling pathway is integral to hair follicle circulation and the stability of hair follicle stem cells.
• mTOR signaling is implicated as a key factor in hair follicle damage and degeneration associated with Vitamin D receptor (VDR) deficiency.
• Dysregulation of mTOR signaling contributes to alopecia disorders.

Conclusions:

• The mTOR pathway is a crucial regulator of hair follicle homeostasis.
• Targeting mTOR signaling may offer therapeutic strategies for alopecia and VDR deficiency-related hair disorders.
• Further research into mTOR's molecular mechanisms in hair follicles is warranted.
