In this review, the potential role of the hormone prolactin in skin biology and its implications for treating skin diseases and hair disorders are explored, with a focus on its stress-related impacts and possible immunomodulatory function in the context of COVID-19.

In this review, researchers introduced clinically tunable siRNA delivery systems for hair loss treatment, discussing design principles and analyzing relevant clinical trials to propose a framework for optimizing siRNA delivery in a clinical context.

This study found that extracellular vesicles from erythrocytes may promote hair regeneration in patients with androgenic alopecia by transferring components that upregulate Wnt/β-catenin signaling and are involved in the formation of the skin's outer barrier.

This chapter reviews hair anatomy, hair shaft structure, and various cosmetic treatments that can alter or damage hair, but it presents no new research findings.

This study found that the phenotype of Hedgehog/Gli-driven skin tumors in mice depends on the cell of origin, tissue context, and level of oncogenic signaling.

This review discusses medical treatments for hirsutism, focusing on oral contraceptives and other therapies, but reports no new results; the authors emphasize the lack of evidence for insulin sensitizers in treating hirsutism alone.

This chapter reviews keratins in skin epithelia, including their roles in cellular function and disease, and reports no new experimental results.

This study found that age and follicular miniaturization were extremely weak predictors of total hair count in women with hair loss.

This study found that L-type channel blockers can induce hair growth in Timothy syndrome by overcoming delays in anagen phase, suggesting a potential therapeutic role for tissue regeneration.

This review examines microneedle patches for drug delivery, detailing their designs, materials, manufacturing methods, and potential advantages, but reports no new clinical results.

This review discusses advances in understanding the mechanisms behind radiation-induced skin reactions, highlighting recent insights into the roles of stem cells and immune cells in injury mitigation and late carcinogenesis, as reported in the context of ionizing radiation exposure.

This study suggests that Keratin 6hf may be a potential marker of oral squamous cell carcinoma and could play a role in its progression, though further research is needed to understand its function.

This review discusses the complex role of the EDA pathway in vertebrate skeletal development, emphasizing its interaction with other morphogenic pathways to influence skeletal diversity, but reports no new experimental results.

This study introduces stem cell activity as a key factor influencing the effects of IFN-γ and TGF-β1 on autoimmune disease dynamics, showing that varying cytokine levels can modulate stem cell activity and immune privilege, impacting tissue regeneration and disease flares.

This study found that in Liaoning cashmere goats, overexpression of the PIP5K1A gene enhances skin fibroblast proliferation, while interference with this gene reverses melatonin-induced proliferation, and PIP5K1A regulates certain miRNA expressions, suggesting a role in improving cashmere yield and quality.

This study used Cisd2 knockout mice models and found that these mice display premature aging characteristics and an increase in dysfunctional neutrophils, suggesting Cisd2's role in calcium homeostasis and neutrophil function via interactions with Calnexin and SERCA.

Hormonal contraceptives are effective for teens but require careful consideration of side effects and individual health.

This study suggests that stress may worsen Tourette syndrome symptoms in mice by increasing allopregnanolone synthesis, with findings supporting finasteride as a potential treatment to manage symptom fluctuations.

This review discusses the mechanisms, applications, and research evidence of photobiomodulation, highlighting its efficacy, safety, and potential for standardized evaluation methods, but reports no new clinical results.

This study investigated the hair of German shepherd dogs, revealing variations in color, shape, and band patterns across different body regions, while all hair types shared similar anatomical structures such as continuous, vacuolated medullas and cuticular scales with smooth or rippled margins.

In this study, researchers examined androgen receptor activity in the adult mouse brain and found specific expression in key brain areas, which could inform understanding of cognitive side effects in humans undergoing androgen deprivation therapy for prostate cancer.

This study introduces a modular fiber model to investigate how changes in microstructural properties of wool affect its critical buckling load, highlighting potential uses and areas needing further research in wool fiber biophysics.

Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.

This review covers recent findings on stem cell plasticity under normal and cancerous conditions but presents no new experimental results, highlighting implications for regenerative medicine and cancer treatments.

This review discusses the role of immune privilege collapse in the pathogenesis of alopecia areata, emphasizing the potential for therapeutic manipulation of hair bulb immune privilege to offer new treatment options, and reports no new results.

This review discusses the basic biology of apoptosis and its relevance to skin diseases, without presenting new research findings.

This study provides new insights into the identification and expression patterns of miRNAs in wool follicles, which could improve understanding of wool follicle development in sheep.

This study found that CK15 is an unreliable marker for assessing bulge zone integrity in cicatricial alopecia follicles due to its altered expression in diseased conditions.

Forensic medicine is crucial for justice and needs continuous innovation and technology integration.

This study discusses how different modes of regulated cell death in keratinocytes affect skin stem cell niches, and their role in skin inflammation, injury repair, and cancer, based on findings from human dermatological conditions and experimental mouse models.
