570-600 / 1000+ resultsresearch Stress-induced production of chemokines by hair follicles regulates the trafficking of dendritic cells in skin
Hair follicles help attract immune cells to the skin during stress.
research Organogenesis From Dissociated Cells: Generation of Mature Cycling Hair Follicles From Skin-Derived Cells
Scientists have found a way to create hair follicles from skin cells of newborn mice, which can grow and cycle naturally when injected into adult mouse skin.
research Immunohistochemical localization of types 1 and 2 5α-reductase in human scalp
The study found that two enzymes linked to hair loss are located in different parts of the scalp, supporting a common treatment's effectiveness.
research The role of the microbiome in scalp hair follicle biology and disease
The scalp's microorganisms significantly affect hair health and disease.
research T helper 17 cell/regulatory T-cell imbalance in hidradenitis suppurativa/acne inversa: the link to hair follicle dissection, obesity, smoking and autoimmune comorbidities
An imbalance between certain immune cells is linked to a chronic skin condition and may be influenced by obesity, smoking, and autoimmune issues.
research Keratin 79 identifies a novel population of migratory epithelial cells that initiates hair canal morphogenesis and regeneration
Keratin 79 marks a new group of cells that are key for creating and repairing the hair follicle's structure.
research Stem cell markers (cytokeratin 15, CD34 and nestin) in primary scarring and nonscarring alopecia
Scarring alopecia affects different hair follicle stem cells than nonscarring alopecia, and the infundibular region could be a new treatment target.
research Hair follicles, their disorders and their opportunities
Hair follicles offer promising targets for delivering drugs to treat hair and skin conditions.
research Keratoacanthoma and other types of squamous cell carcinoma with crateriform architecture: Classification and identification
Keratoacanthoma and some squamous cell carcinomas are linked to hair follicles, while others are not.
research The Transverse Anatomy of Androgenic Alopecia
The study found that horizontal sections of scalp biopsies are better for analyzing hair loss, showing fewer hairs and more fine hairs in balding areas.
research Traumatic Alopecia in Trichotillomania: a Pathogenic Interpretation of Histologic Lesions in the Pilosebaceous Unit*
Skin biopsy can help diagnose hair loss from trichotillomania.
research Seborrheic Keratoses and Trichostasis Spinulosa
Seborrheic keratoses may partly come from hair follicle cells.
research A case of localized follicular hamartoma: an ultrastructural and immunohistochemical study
The hamartoma is an abnormal hair growth with limited development in the upper hair follicle.
research Tight junctions form a barrier in porcine hair follicles
Tight junctions create a barrier in pig hair follicles that controls what can enter the skin.
research Chloracne: histopathologic findings in one case
Tiny infundibular cysts are the main lesions in chloracne, not comedones.
research Loss of Gata6 causes dilation of the hair follicle canal and sebaceous duct
Removing Gata6 causes hair follicle and sebaceous duct enlargement.
research IMMUNOPATHOLOGY OF THE HUMAN HAIR FOLLICLE
The document concludes that immune system abnormalities cause alopecia areata, but the exact process is still not completely understood.
research Increasing the percutaneous absorption and follicular penetration of retinal by topical application of proretinal nanoparticles
Proretinal nanoparticles improve skin absorption and reduce irritation of topical retinoids.
research Eruptive Vellus Hair Cysts: Report of a New Case with Immunohistochemical Study and Literature Review
Eruptive vellus hair cysts are rare, benign skin lesions that are hard to treat.
research Cutaneous Adnexal Cysts Revisited: What We Know and What We Think We Know
A new classification system for skin cysts was proposed to improve diagnosis.
research 14-3-3σ Is Required for Club Hair Retention
The 14-3-3σ gene is essential for preventing hair loss.
research Preliminary findings suggest hidradenitis suppurativa may be due to defective follicular support
Hidradenitis suppurativa is likely caused by blocked hair follicles, not apocrine glands.
research Preparing the hair follicle canal for hair shaft emergence
A specific type of skin cell creates an opening for hair to grow out, and problems with this process can lead to skin conditions.
research Controversial Concepts
The author now believes tricholemmal carcinoma is a rare type of infundibular squamous cell carcinoma and more research is needed on these tumors.
research Pathologic Quiz Case: An 84-Year-Old Woman With a Skin Cyst Containing Ziehl-Neelsen–Positive Structures
Basal cell carcinoma may originate from vellus hair cysts.
research D2-40 Expression in Primary Scarring and Nonscarring Alopecia
Most people with scarring and nonscarring hair loss show similar D2-40 levels, but some with scarring hair loss have higher levels.
research Perifollicular inflammation and follicular spongiosis in androgenetic alopecia
Hair loss in both Androgenetic Alopecia and Alopecia Areata is often accompanied by inflammation around hair follicles, but the location and severity of this inflammation varies.
research Histopathologic Criteria for Follicular Differentiation
The document outlines criteria to identify and differentiate neoplasms based on follicular characteristics.
