research Commensal Microbes and Hair Follicle Morphogenesis Coordinately Drive Treg Migration into Neonatal Skin
Hair follicle development and microbes help regulatory T cells gather in newborn skin.
research Overexpression of parathyroid hormone-related protein in the skin of transgenic mice interferes with hair follicle development.
Too much parathyroid hormone-related protein in skin disrupts hair growth in mice.
research Human Macrophages Preferentially Infiltrate the Superficial Adipose Tissue
Human body's immune cells are more common in the layer of fat just beneath the skin than in deeper fat layers.
research Cell Types Promoting Goosebumps Form a Niche to Regulate Hair Follicle Stem Cells
Muscles and nerves that cause goosebumps also help control hair growth.
research Macroenvironmental Regulation of Hair Cycling and Collective Regenerative Behavior
Hair growth is influenced by various body and external factors, and neighboring hairs communicate to synchronize regeneration.
research Recent advances in the molecular mechanisms determining tissue sensitivity to glucocorticoids: novel mutations, circadian rhythm and ligand-induced repression of the human glucocorticoid receptor
New findings explain how genetic changes, body clocks, and certain molecules affect tissue response to stress hormones.
research Cutaneous changes in hypothyroidism
Skin can become dry and thick in hypothyroidism.
research Moisture as a Plasticity Switch in Blowouts: Glass-Transition Behavior, Viscoelastic Response, and Tension-Defined Shape
Moisture makes hair flexible for reshaping during blowouts.
research Activation of TRPV3 Regulates Inflammatory Actions of Human Epidermal Keratinocytes
TRPV3 in skin cells causes inflammation and cell death.
research Empathic disequilibrium is related to lower levels of hair oxytocin in humans
research Dynamic characteristics of cerebrovascular reactivity or ventilatory response to change in carbon dioxide
Traditional methods may not fully capture how the brain and breathing systems respond to carbon dioxide changes.
research 518 Nutrient and stress sensing as novel physiological regulator of human hair pigmentation and greying: Role of mTORC1 activity
Blocking mTORC1 activity could increase hair pigmentation and potentially reverse greying.
research The hairless gene mutated in congenital hair loss disorders encodes a novel nuclear receptor corepressor
The mutated hairless gene causes hair loss by acting as a new type of corepressor affecting thyroid hormone receptors.
research Alopecia areata – hyperactivity of the hypothalamic–pituitary–adrenal axis is a myth?
The study found no significant difference in stress hormone levels between people with alopecia areata and healthy individuals, suggesting that the disease is not caused by an overactive stress response system.
research Imbalance of T‐helper 17 and regulatory T cells in patients with alopecia areata
People with alopecia areata have more Th17 cells and fewer Treg cells, which may be key to the condition's development.
research The parathyroid hormone-related protein as a regulator of normal tissue functions
PTHrP regulates various normal body functions, including bone development, skin, and muscle function.
research Multiscale modelling of human hair
Human hair becomes weaker and stretches more easily at higher temperatures.
research Age‐dependent regulation by androgens of gene expression in the anterior hypothalamus and stress‐induced release of adrenal hormones in adolescent and adult male rats
Testosterone affects stress hormone levels differently in adolescent and adult male rats.
research Several biological benefits of the low color temperature light-emitting diodes based normal indoor lighting source
Low color temperature light (1900 K) benefits health by promoting melatonin, protecting eyes, and aiding healing.
research The human hair follicle has established a fully functional peripheral equivalent of the hypothamalic‐pituitary‐adrenal‐axis (HPA)
Human hair follicles can produce stress hormones like the body's main stress response system.
research The Anagen Hair Cycle Induces Systemic Immunosuppression of Contact Hypersensitivity in Mice
Hair growth phase in mice weakens certain immune responses.
research Developmental and evolutionary comparative analysis of a regulatory landscape in mouse and chicken
Gene regulation evolved differently in mouse and chicken skin, but remained stable in their trunks.
research Heat treatment increases the incidence of alopecia areata in the C3H/HeJ mouse model
Heat treatment increases hair loss in certain mice.
research TSH is a novel neuroendocrine regulator of selected keratins in the human hair follicle
TSH influences keratin expression in human hair follicles.
research The compatibility of Bacillus thuringiensis Cry protein-solubilizing buffers with the droplet feeding method in fall armyworm larvae
Thymosin beta 4 protects cells from damage by blocking a harmful microRNA and boosting a protective gene.
research Multi-layered environmental regulation on the homeostasis of stem cells: The saga of hair growth and alopecia
Environmental factors at different levels control hair stem cell activity, which could lead to new hair growth and alopecia treatments.
research Dermo‐epidermal interactions in reptilian scales: Speculations on the evolution of scales, feathers, and hairs
Reptilian scales, feathers, and hairs evolved from changes in skin cell interactions.
research Intrinsic versus Extrinsic Aging: A Histopathological, Morphometric and Immunohistochemical Study of Estrogen Receptor β and Androgen Receptor
The study concluded that both estrogen and androgen receptors, which decrease with age, are linked to skin aging and may be hormonally regulated.
research The Thinning Top: Why Old People Have Less Hair
Old people have less hair because their hair follicles don't regenerate as well, not because of fewer stem cells, and a protein called follistatin might help reactivate hair growth.
