research The role of dexamethasone in mediating the contradictory effects of Wnt antagonists SFRP2 and SFRP3 on human hair follicle growth
Dexamethasone affects hair growth by altering levels of proteins that either promote or inhibit hair follicle growth.
research Vitamin D and Human Health: Lessons from Vitamin D Receptor Null Mice
Mice without the vitamin D receptor have bone issues and other health problems, suggesting vitamin D is important for preventing various diseases in humans.
research Distinct stem cells contribute to mammary gland development and maintenance
Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.
research Is dehydroepiandrosterone a hormone?
Dehydroepiandrosterone (DHEA) is a prohormone important for producing sex steroids and has potential health benefits.
research The cutaneous serotoninergic/melatoninergic system: securing a place under the sun
Human skin can make serotonin and melatonin, which help protect and maintain it.
research Sexual Hormones in Human Skin
Human skin makes sexual hormones that affect hair growth, skin health, and healing; too much can cause acne and hair loss, while treatments can manage these conditions.
research Melatonin in the skin: synthesis, metabolism and functions
Melatonin in the skin helps protect against damage from stress and UV rays, and could be used to treat certain skin conditions.
research Neurosteroidogenesis Is Required for the Physiological Response to Stress: Role of Neurosteroid-Sensitive GABAAReceptors
Neurosteroids are crucial for stress response, and targeting specific receptors may help treat certain disorders.
research The 5 Alpha-Reductase Isozyme Family: A Review of Basic Biology and Their Role in Human Diseases
The document concludes that the 5 alpha-reductase enzymes are important in steroid metabolism and related to various human diseases, with inhibitors used to treat conditions like male pattern baldness and prostate issues.
research A genome-wide association scan in admixed Latin Americans identifies loci influencing facial and scalp hair features
Genetic factors influence hair traits like shape, color, and greying in Latin Americans.
research Stress Inhibits Hair Growth in Mice by Induction of Premature Catagen Development and Deleterious Perifollicular Inflammatory Events via Neuropeptide Substance P-Dependent Pathways
Stress stops hair growth in mice by causing early hair growth phase end and harmful inflammation through a specific nerve-related pathway.
research Macrophages Regulate Schwann Cell Maturation after Nerve Injury
Macrophages help heal nerves by aiding the maturation of Schwann cells and are important for nerve repair.
research A role of melatonin in neuroectodermal‐mesodermal interactions: the hair follicle synthesizes melatonin and expresses functional melatonin receptors
Hair follicles produce and respond to melatonin, affecting hair growth and sensitivity to estrogen.
research Stress exposure modulates peptidergic innervation and degranulates mast cells in murine skin
Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.
research Convergent Genesis of an Adult Neural Crest-Like Dermal Stem Cell from Distinct Developmental Origins
Skin-derived precursors in hair follicles come from different origins but function similarly.
research A role for p75 neurotrophin receptor in the control of apoptosis‐driven hair follicle regression
The p75 neurotrophin receptor is important for hair follicle regression by controlling cell death.
research Changes in Expression and Function of Extrasynaptic GABAAReceptors in the Rat Hippocampus during Pregnancy and after Delivery
Pregnancy increases certain GABAA receptors in rat brains, influenced by steroid levels.
research Intracrinology and The Skin
DHEA stimulates skin oil glands and could help postmenopausal women, with potential for acne and excessive hair growth treatments.
research Regulated Proenkephalin Expression in Human Skin and Cultured Skin Cells
Human skin cells produce proenkephalin, which changes with environmental factors and skin diseases.
research Acne and Systemic Disease
Hormones, especially androgens, play a key role in acne, which can be a symptom of systemic diseases like PCOS and may require targeted treatment.
research Reversing wrinkled skin and hair loss in mice by restoring mitochondrial function
Restoring mitochondrial function in mice reversed their skin wrinkling and hair loss.
research Beyond Expectations
Keratin proteins are crucial for healthy skin, but mutations can cause skin disorders with no effective treatments yet.
research Pathways to inflammation: acne pathophysiology
Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.
research 46,XY DSD due to impaired androgen production
Impaired androgen production in 46,XY DSDs causes ambiguous genitalia and requires long-term care.
research Exogenous IGF-1 promotes hair growth by stimulating cell proliferation and down regulating TGF-β1 in C57BL/6 mice in vivo
IGF-1 injections help mice grow more hair by increasing cell growth and blocking a hair growth inhibitor.
research Hair Germ Model In Vitro via Human Postnatal Keratinocyte-Dermal Papilla Interactions: Impact of Hyaluronic Acid
Adding hyaluronic acid helps create larger artificial hair follicles in the lab.
research Comprehensive molecular and cellular studies suggest avian scutate scales are secondarily derived from feathers, and more distant from reptilian scales
Bird scales evolved from feathers, not reptile scales.
research A primer for studying cell cycle dynamics of the human hair follicle
The document concludes that understanding hair follicle cell cycles is crucial for hair growth and alopecia research, and recommends specific techniques and future research directions.
research Vasoactive intestinal peptide, whose receptor-mediated signalling may be defective in alopecia areata, provides protection from hair follicle immune privilege collapse
A substance called VIP might protect hair follicles from being attacked by the immune system, and problems with VIP signaling could lead to hair loss in alopecia areata.
