This review discusses the potential autoimmune pathogenesis and various contributing factors of alopecia areata, noting that current treatments remain palliative while emerging therapies offer new hope for extensive cases.

This review discusses the mechanisms and pathways of FGFR signalling and its roles in development, disorders, and therapeutic targeting, but reports no new clinical results.

This study highlights the potential increased frequency of advanced liver disease in obese PCOS patients with NAFLD and underscores the importance of lifestyle modifications as initial treatment.

This review examines the dermatologic effects of tobacco use and nicotine, noting potential benefits and drawbacks for various skin conditions, but reports no new clinical results.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

This summary explains the different types of wrinkles, their causes, and their distinct microanatomical characteristics, noting that each type may respond differently to treatments.

This study found that laminin-511 is crucial for hair morphogenesis in mice, as it influences primary cilia formation and dermal papilla maintenance through noggin and sonic hedgehog signaling.

This review reports on the dual aspect of fullerene in skincare, highlighting its beneficial antioxidant properties as well as potential toxicity and skin cell reactions, while identifying areas for future research.

In this study, the researchers reported that Notch/CSL signaling is crucial for hair follicle differentiation, with Wnt5a signaling and FoxN1 acting as mediators in mice.

This review describes the roles of 5α-reductase isozymes in prostate development and pathology and reports no new clinical results.

This paper discusses X-linked ichthyosis and its genetic causes, focusing on biochemical pathways and their role in epidermal differentiation and barrier function, but it presents no new clinical findings.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This article discusses the history taking and clinical examination process for diagnosing alopecia and outlines a diagnostic approach, noting that it reports no new clinical results.

This study found that epidermal Wnt production is crucial for forming the skin's spinous layer through a BMP-FGF signaling cascade, although Wnt from basal cells is not needed for their differentiation.
