This study found various ABC transporters are transcribed in human hair follicles, suggesting their possible role in HF biology and potential for new therapeutic interventions.

This study found that specific gene upregulations and mutations in hidradenitis suppurativa skin support the role of inflammation, altered epithelial differentiation, and metabolism dysregulation in the disease's pathogenesis.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

In this study, researchers found that the G(S)alpha subunit is strongly expressed in neonatal mouse hair follicles, indicating it may play a role in initiating follicle growth.

This study demonstrated that a mechanical-chemical cascade involving dermal cell contraction and the activation of Piezo1 in epidermal cells is crucial for initiating interactions necessary for hair follicle regeneration in skin organoids.

This study reports that bone marrow derived cells can become a source of epithelial cells in tumor development, contributing significantly to skin lesions like papillomas and ulcers in a skin carcinogenesis model.

This study reports for the first time on the expression patterns of Id2 and Id3 proteins in developing hair follicles, suggesting a significant role for these proteins in hair follicle development and epithelial-mesenchymal interactions.
