This review synthesizes recent research to propose a precision framework for treating androgenetic alopecia and alopecia areata based on genetic insights and pathway biology, highlighting the roles of androgen-receptor signaling, immune dysregulation, and emerging therapies like regenerative medicine and AI-assisted diagnostics.

This study found that specific immune cell phenotypes, particularly CD25 on CD4 Treg cells, were causally linked to androgenic alopecia, suggesting potential targets for immune-based therapies.

This review discusses the insights gained from single-cell RNA sequencing of fibroblasts in various cancers and wound healing, highlighting differences in gene expression and novel interactions.

This study found that a catalytically active version of Vav2 significantly altered gene expression patterns in hair follicle stem cells in mice, with these changes varying over the animals' lifespans.

This study suggests that hair follicle dermal stem/progenitor cells play a key role in both hair regeneration and skin wound healing, with potential implications for preventing hair follicle miniaturization linked to aging or alopecia.

In this study, researchers identified a gene expression pre-pattern and implicated the Wnt inhibitor Dickkopf 4 in the formation of color patterns in domestic cat embryos.

Alopecia Areata is an autoimmune condition causing hair loss with no cure and treatments that often don't work well.

This study found that aging in the epidermis disrupts cytokine balance and stem cell function, which may contribute to broader tumor-suppressive mechanisms.

This study reports previously unrecognized cellular complexity in growing mouse incisors, suggesting species-specific differences in cell dynamics between mouse and human teeth related to growth and differentiation.
