This study found that Hairless protein down-regulates Msx2 expression, affecting hair follicle formation in Hairpoor mice by altering the MSX2 regulatory pathway.

This research found that reduced expression of SIRT1 in human scalp tissue may contribute to alopecia areata development by inducing immune-inflammatory responses in hair follicle cells, suggesting that SIRT1 plays a regulatory role in hair follicle immunity.

This study found that androgens downregulate BMP2 in dermal papilla cells, inhibiting hair follicle stem cell differentiation, while BMP2 addition may restore hair lineage differentiation through the Wnt/β-catenin pathway.

This study found that testosterone administration reduced the expression of uterine receptivity molecules in ovariectomized rats, which may negatively affect early pregnancy establishment and female fertility.

In this study on cultured human dermal papilla cells, researchers found that niacinamide may enhance hair growth by reducing oxidative stress-induced cell senescence and delaying catagen entry, suggesting potential applications against hair loss.

This review summarizes discussions from a 2010 stem cell biology meeting, covering the origin, behavior, and therapeutic potential of pluripotent and multipotent stem cells, without reporting new experimental findings.

In this study, periodic exposure to red light in aged mice led to increased histone acetylation and activated mitochondrial fatty acid oxidation, which collectively mitigated cellular aging by modulating metabolism, inflammation, and gene expression.

Using a higher concentration of triamcinolone acetonide leads to faster hair regrowth in scalp patchy alopecia areata.

This study found that sulfated CCK octapeptide reduces psoriasis-like skin inflammation in mice, suggesting a new pathophysiological role for CCK in regulating epidermal inflammation.

This study found that periodic red light exposure in aged mice increased histone acetylation and activated metabolic processes in keratinocytes, mitigating cellular aging through enhanced fatty acid oxidation and altered gene expression related to lipid metabolism.

This study found that periodic red light exposure increased histone acetylation and activated metabolic processes in aged mice, leading to enhanced fatty acid oxidation and the mitigation of cellular aging by influencing gene expression and metabolic regulation.

This study found that Blimp1 plays a key role in promoting hair follicle morphogenesis and growth by mediating inductive signaling pathways in dermal papilla cells.

This study found that the antiandrogen drug enzalutamide reduced TMPRSS2 levels and significantly decreased SARS-CoV-2 entry and infection in lung cells, supporting further clinical trials for COVID-19 treatment.

This study found that proper levels of retinoic acid, controlled by the enzyme Cyp26b1, are essential for normal hair follicle development and morphogenesis in mice.

This review discusses the increased incidence of dermatological conditions in individuals with Down's syndrome and explores potential links to immunological deficiencies, but reports no new clinical findings.

This study found that the loss of Msx2 in knockout mice led to phenotypes similar to Peters anomaly and microphthalmia, suggesting that MSX2 plays a critical role in anterior segment development of the eye.

This study investigated immune dysregulation in individuals with Down syndrome and found that treatment with the JAK inhibitor tofacitinib improved skin conditions like alopecia areata and reduced autoimmune markers without severe side effects. Additional research is necessary to understand its broader impacts.

This systematic review indicates that patients with Down syndrome have an increased prevalence of various dermatologic disorders, especially infectious, inflammatory, autoimmune, and connective tissue conditions.

This study found that in estrogen receptor-positive breast cancer cells, 17β-estradiol repressed polyamine oxidase transcription by interacting with AP-1 sites on its promoter.

In this study, a herbal extract mixture significantly reduced IL-1α gene expression in HaCaT cells, suggesting it may aid in the treatment of nonscarring alopecia.

This study found that WWOX deficiency in mice leads to impaired skin development, reduced epidermal thickness, and significant hypothermia due to disrupted cell proliferation and homeostasis.

This study observed that adding low-level light therapy with the GentleWaves® device to Minoxidil significantly boosted hair regrowth in men with androgenetic alopecia by reducing scalp inflammation.

This study observed that individuals with Down syndrome exhibit early immune dysregulation, including multi-organ autoimmunity and hypercytokinemia, and found that the JAK inhibitor tofacitinib showed a good safety profile and reduced skin pathology in a Phase II trial.

In this open-label trial, Tofacitinib was well tolerated and improved IFN and cytokine scores, as well as overall skin pathology, in individuals with Down syndrome and immune skin conditions.

Following COVID-19 vaccination, this case report observed that a 31-year-old male displayed a significant abnormal autoimmune response, leading to suspected undifferentiated connective tissue disease possibly overlapping rheumatoid arthritis and SLE, despite negative autoimmune markers prior to surgery.

This study found that corticotropin-releasing factor influences cytokine expression related to hair growth in human dermal papilla cells and suggests CRF receptor antagonists could be potential treatments for stress-induced hair loss.

In this study, Urtica dioica extract was found to significantly downregulate 5-alpha-reductase type II gene expression in skin cells, suggesting potential usefulness against androgenic skin diseases.

Baricitinib can help improve hair loss and skin color issues in people with Down syndrome.

This study developed a method for designing peptide-based PROTAC drugs using advanced AI models, successfully identifying peptides that bind to specific receptors and incorporating them into a potential transdermal treatment for androgenetic alopecia.

This study identified downstream genes regulated by androgen receptor signaling in dermal papilla cells and suggests potential molecular targets for treating androgenetic alopecia and prostate cancer.
