In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

This study found that stress increases the number of peptidergic nerve fibers and mast cell activity in mouse skin, suggesting a significant neuro-immune interaction under stress.

This study suggests that nerve growth factor plays a crucial role in the stress-induced termination of hair growth in mice, and its antagonism might offer a therapeutic approach to mitigate stress-related hair loss.

The TGF-β family helps control how cells change and move, affecting skin, hair, and organ development.

This study found that Sonic Hedgehog secreted by hair follicle transit-amplifying cells is essential for dermal adipogenesis and hair follicle growth by acting on adipocyte precursors.

This review discusses the role of keratins in maintaining epidermal structure and function and reports no new results; the authors emphasize the lack of rational therapies for skin disorders linked to keratin mutations.

This study in mice demonstrated that stress or nerve growth factor injection increases sensory neuron activity related to skin innervation, suggesting a strong connection between stress perception and neurogenic skin inflammation.

This study found that biallelic mutations in the TTC7A gene affect lymphocyte and gut epithelial cell function, thereby contributing to the development of inflammatory bowel disease in patients.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.

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 trichohyalin, a protein previously thought to be restricted to hair and tongue, is also present in isolated cells within the granular layer and stratum corneum of normal human epidermis.

This study identified a novel G207E STING mutation associated with severe inflammatory symptoms and suggested that common polymorphisms in TMEM173 and IFIH1 may modify the phenotype in affected individuals.

This study reported that alopecia occurred in 2.5% of patients with mycosis fungoides or Sézary syndrome, with some cases resembling alopecia areata and others associated with specific skin lesions.

This study observed that in wild snowshoe hares, gene expression patterns during seasonal coat color change show a consistent lag between gene expression and visible coat color changes.

This study reported that prenatal exposure to dihydrotestosterone altered long-term androgen metabolism in juvenile male rats, suggesting different regulatory mechanisms for 5a-reductase in hypothalamic versus pituitary tissues.

This study in cashmere goats found that DNA methylation levels were lower during hair follicle differentiation compared to induction, suggesting it plays a critical role in gene regulation for hair morphogenesis.

This study found that dermal papilla cells cultured in vitro can promote hair follicle regeneration and maintain hair growth, with stronger ET-1 and SCF expression enhancing this regenerative ability.

This study found that a stochastic follicular automaton model replicates hair follicle cycle fluctuations, with deterministic simulations aligning with steady-state levels as follicle numbers increase.

This study found that prenatal exposure to androgens caused long-lasting heart remodeling and left ventricular hypertrophy in female mice offspring, suggesting potential cardiac risks for daughters of mothers with PCOS.

This review discusses how certain genetic, infectious, and metabolic conditions might influence disease severity and highlights the potential for new therapies, but it presents no new research findings.

This study found that the proteins GDNF, NTN, GFRα-1, GFRα-2, and c-Ret are differentially expressed during various stages of the human hair follicle cycle, with potential implications for hair biology.

This study analyzes the cultural ideology of female body image as portrayed in makeover TV programs, focusing on the impact of patriarchy, but it reports no new empirical results.

This review examines the role of P-cadherin in skin and hair biology, emphasizing its importance in human hair growth, cycling, and pigmentation, and reports no new research findings.

This study found that low doses of bisphenol A may increase proliferation of the ventral prostate in adult rats by altering the estrogen to androgen ratio and gene expression.

The document concludes that better understanding the wound microbiome can improve chronic wound care by preserving helpful bacteria and targeting harmful ones.

This review discusses the impact of testosterone therapy on postmenopausal women's sexual function and well-being but notes a lack of long-term safety studies and debates on defining androgen insufficiency.

This study found that Celsr1, not Celsr2, is the primary protein involved in establishing planar cell polarity and hair follicle polarization in the epidermis of mice.

This study found that the imidacloprid/flumethrin collar (Seresto®) is chemically compatible with major spot-on formulations and dermally and systemically safe for adult dogs and cats when used together.

This study introduced RoPod, a customizable tool for low-stress live imaging of Arabidopsis roots, which improves data reproducibility and provides new insights into plant autophagy by revealing detailed, cell type-specific responses to chemical modulators.
