research Combined melanocytic nevus presenting with scalp alopecia associated with alopecia areata: Coincidence or causal?
A man's scalp hair loss was due to a combined melanocytic nevus and alopecia areata, suggesting a possible link between the two conditions.
research Differentiation of CD34+ Human Hair Follicle Stem Cells into Functional Melanocytes
CD34+ hair follicle stem cells can become melanin-producing cells for treating skin conditions.
research 1339 Casein kinase 1 inhibition in keratinocytes enhances the migration of melanocyte precursors in the hair follicle via KitL/c-Kit signaling pathway
Blocking casein kinase 1 in skin cells can help melanocyte precursors move better, potentially helping with conditions like vitiligo or gray hair.
research 085 Autoantigen screening in C3H/HeJ mouse model of alopecia areata revealed high antigenicity of melanocyte-associated antigen epitopes
Melanocyte-associated antigens may play a key role in alopecia areata and could be targets for new treatments.
research Stress-sensing in the human greying hair follicle: Ataxia Telangiectasia Mutated (ATM) depletion in hair bulb melanocytes in canities-prone scalp
Hair greying is linked to reduced ATM protein in hair cells, which protects against stress and damage.
research Melan-A Positive cells significantly expressed in immune-targeted follicles of Alopecia Areata
Melanocytes may trigger the immune response in alopecia areata, affecting hair regrowth.
research Melanocyte Pygmentation – Friend or Foe on the Route to Melanoma
Darker skin provides more protection against UV damage and cancer.
research An implication for post-transcriptional control: Reciprocal changes of melanocortin receptor type 2 mRNA and protein expression in alopecia areata
Alopecia areata may involve stress-related changes affecting hormone receptors, leading to reduced cortisol production.
research ISID1403 - Melatonin protects K15+ human hair follicle stem cells against paclitaxel-induced damage ex vivo
Melatonin may protect hair follicle stem cells from damage caused by chemotherapy.
research MSC-derived exosomes protect auditory hair cells from neomycin-induced damage via autophagy regulation
Exosomes protect ear hair cells from damage by controlling cell waste removal, potentially helping treat hearing loss.
research Subclinical speckled perifollicular melanosis of the scalp.
The scalp has a natural speckled pattern of increased pigment around hair follicles, possibly linked to local hormone production.
research HAIR FOLLICLE STEM CELLS IN THE PATHOGENESIS OF PRIMARY CICATRICIAL ALOPECIA
Damage to hair follicle stem cells may cause permanent hair loss and scarring in PCA.
research Location and fine structure of melanocytes in human fetal scalp hair follicles.
Melanocytes in the outer root sheath are likely stem cells that grow fast but stay immature.
research Keratinocyte Stem Cells but Not Melanocyte Stem Cells Are the Primary Target for Radiation-Induced Hair Graying
Radiation mainly affects keratinocyte stem cells, not melanocyte stem cells, causing hair to gray.
research Targeted Knockout of β-Catenin in Adult Melanocyte Stem Cells Using a Mouse Line, Dct::CreERT2, Results in Disrupted Stem Cell Renewal and Pigmentation Defects
Removing β-catenin in certain stem cells causes hair whitening and pigmentation issues.
research Pigmented contact dermatitis due to therapeutic sensitizer as complication of contact immunotherapy in alopecia areata
Some patients with severe alopecia areata developed skin darkening from their treatment, which may indicate a less effective response to the therapy.
research Photoageing of Hair Fiber and Photoprotection
Sunlight damages hair, causing cuticle loss, protein changes, and discoloration.
research Stable analytic extrapolations in the theory of strong interactions
Oxidative stress causes hair graying by damaging hair follicle melanocytes more than skin melanocytes.
research 1200 The biology of melanocytes
Melanocytes are cells that make skin and hair color and help protect skin from sun damage.
research 1403 Melatonin protects K15+ human hair follicle stem cells against paclitaxel-induced damage ex vivo
Melatonin may help prevent hair loss caused by the chemotherapy drug paclitaxel.
research Weathering of the hairless scalp: a study using skin capacitance imaging and ultraviolet light-enhanced visualization
The study found that long-term sun exposure does not significantly affect follicular plugs on the scalp, and the scalp's appearance is unique compared to other body parts.
research Detection of Functionally Active Melanocortin Receptors and Evidence for an Immunoregulatory Activity of α-Melanocyte-Stimulating Hormone in Human Dermal Papilla Cells
αMSH may help regulate immune responses in hair follicles and its disruption could lead to hair loss.
research Editor's evaluation: Crosstalk with keratinocytes causes GNAQ oncogene specificity in melanoma
Keratinocytes can reduce the survival of certain melanoma cells, suggesting new therapy paths.
research 1363 Hair follicle growth and pigmentation during ageing
The research found that a specific skin cell type not only triggers hair growth but also controls hair color, and that aging can lead to hair loss and color changes.
research A Guide to Assessing Damage Response Pathways of the Hair Follicle: Lessons From Cyclophosphamide-Induced Alopecia in Mice
The document concludes that assessing hair follicle damage due to cyclophosphamide in mice involves analyzing structural changes and suggests a scoring system for standardized evaluation.
research Field melanin mapping of the hairless scalp
The study found a specific pattern of uneven melanin distribution on balding scalps that could help understand skin diseases caused by light exposure.
research Melanocyte Subpopulation Turnover During the Human Hair Cycle: An Immunohistochemical Study
Melanocyte activity in hair follicles is linked to the hair growth cycle, being active in growth phases and inactive in rest phases.
research Hair repigmentation in microcystic adnexal carcinoma
Hair repigmentation can indicate malignancy and should be investigated.
research Stabilization of β-catenin promotes melanocyte specification at the expense of the Schwann cell lineage
