This study found that light stimulation of intrinsically photosensitive retinal ganglion cells in the eyes can activate hair follicle stem cells through a neural circuit involving the sympathetic nervous system.

This paper discusses the variability in COVID-19 susceptibility and severity, emphasizing factors like biological differences and suggesting potential precision medicine approaches, but it reports no new clinical results.

This study found that estrogen receptor beta, not alpha, is the main mediator of estrogen action in human skin and hair follicles, suggesting a distinct role in these tissues.

This chapter reviews the role of androgen receptors in mediating the actions of androgens in specific tissues and provides no new experimental findings.

This review discusses neural mechanisms involved in hair growth control, focusing on piloneural interactions, but reports no clinical findings; the authors suggest further exploration for managing hair growth disorders.

TGF-β1 from dermal papilla cells suppresses hair growth, and targeting it may help treat androgenetic alopecia.

This article reviews various topics discussed at a workshop on hair disorders, focusing on hair biology, diagnosis, and challenges in therapy evaluation, without presenting new clinical findings.

This review summarizes existing research on the use of finasteride for treating androgenetic alopecia in men, reporting its effectiveness at 1 mg/day and a strong safety profile, but presents no new findings.

This study found that in vitro treatments with 5alpha-reductase inhibitors and androgen receptor antagonists strongly stimulate VEGF expression in dermal papilla cells.

This study found that Israeli patients with alopecia areata had a higher prevalence of comorbid conditions, including food allergies and chronic spontaneous urticaria, compared to matched controls.

This study found that among Japanese women with diffuse hair loss, decreased hair density without changes in vellus hair was the most common and distinct pattern observed, highlighting differences from previous observations in other populations.

This review discusses rodent models of alopecia areata and suggests they are crucial for understanding the autoimmune mechanisms and potential treatments but reports no new clinical results.

This review discusses various aspects of hair color, including its formation and evolutionary variations, based on research presented at the 4th Intercontinental Meeting of Hair Research Societies 2004, without providing new experimental results.

This review discusses the clinical challenges in treating alopecia areata with off-label therapies, highlighting the need to consider new research on JAK inhibitors, but reports no new clinical results.

This article reviews the role of epithelial-mesenchymal interactions in hair follicle morphogenesis and the hair cycle, suggesting potential paths for developing treatments for hair growth disorders but providing no new clinical findings.

This study reports that overexpression of activin in transgenic mice enhances granulation tissue formation during wound healing, highlighting a novel role for activin in cutaneous repair processes.

This review discusses the roles of androgens in female mammals, focusing on how androgen receptor activity in pig reproductive organs may influence ovulation rate and litter size, but reports no new experimental results.

In this study, researchers observed that reproductive experience in female rats altered fear memory and medial prefrontal cortex (mPFC) activity, with pregnant and parous rats showing impaired fear recall compared to nulliparous controls, highlighting the influence of pregnancy-related neurosteroids on cognitive function and brain activity.

This review discusses the roles of sebaceous gland activity, Malassezia yeast, and individual susceptibility in scalp flaking disorders, including dandruff and seborrheic dermatitis, but reports no new experiment results.

This study reveals an antagonistic competition between BMP and Wnt signaling within stem cells, influencing their fate towards hair germ characteristics based on the BMP/Wnt activity ratio.

This study found that BMP signaling influences hair pigmentation in mice by affecting the Agouti protein and interacts with MC-1R pathways to modulate melanin production.

This case report describes a patient with sarcoidosis who experienced severe symptomatic hypercalcemia, scarring alopecia, and acute-on-chronic kidney failure.

This medical case report describes a 69-year-old man's diagnosis and management of ANCA-associated vasculitis leading to rapidly progressive glomerulonephritis, ultimately treated with glucocorticoids and rituximab.

This study found that transgenic expression of COX-2 in mouse basal keratinocytes causes epidermal hyperplasia and certain dysplastic features at specific body sites.

This study reports that the DMI3 gene, essential for nodule formation in legume-rhizobial symbiosis, encodes a calcium/calmodulin-dependent protein kinase, highlighting its role in multiple plant symbioses.

This study introduces a method for long-term expansion of adult mouse epidermal stem cells in vitro using an organoid culture system that maintains the basal-apical organization.

This review highlights capsaicin's chemical properties, natural sources, and its potential benefits such as antioxidant, anti-inflammatory, and analgesic effects, while also noting its challenges in food applications regarding dosage, taste perception, and regulatory compliance.

This study used cryoelectron microscopy to unveil the structure of LPA-bound human LPAR6, revealing unique ligand binding and recognition modes distinct from LPAR1, which may aid in designing targeted compounds for hair loss and cancer.

This study found that 17-beta-estradiol inhibits hair growth in mice by blocking hair follicles in the telogen phase, whereas an estrogen receptor antagonist promotes hair growth by initiating anagen.

This article proposes that alopecia areata may be caused by immune attacks on hair follicles after an immune privilege collapse, suggesting new therapeutic approaches targeting this immune response pattern.
