Applying pseudoceramide improved skin and hair health.

This study found that long-term hair follicle stem cells originate from embryonic progenitor cells in a niche with reduced Wnt/β-catenin signaling, which is essential for their specification.

This study found that human iPSC-derived dermal papilla precursor cells can regenerate hair follicle structures, offering a potential new treatment approach for permanent alopecia.

This study reported that the pseudoceramide bis-oleamido isopropyl alcohol (BOI) promotes hair growth in ex vivo cultured human hair follicles, likely by enhancing sphingolipid synthesis in dermal papilla cells.

This study found that inactivating CerS4 in mouse epidermis disrupts lipid homeostasis and is crucial for maintaining, but not forming, the skin barrier.

This study reports on the vulnerability of hair's structural lipids to physical and chemical damage and describes properties of hair treated with a synthesized ceramide derivative.

This study found that mice deficient in ceramide synthase 4 showed altered sebum composition and progressive hair loss due to obstructed hair canals.

Ceramide Synthase 4 is crucial for healthy skin barrier function.

This study reports a novel LC/MS method that separates and analyzes all known ceramide subclasses in human stratum corneum, identifying a new subclass, CER [EOdS], with minimal sample preparation.

This study suggests that alkaline phosphatase-regulated expression of CCL5 contributes to the trichogenicity of human dermal papilla spheres.

This study demonstrated that mitochondrial function in keratinocytes is crucial for maintaining skin homeostasis and hair follicle development, as its impairment led to disrupted hair morphogenesis and early death in mice.

The researchers reported that iPSCs derived from Sendai virus reprogrammed blood cells can mature into functional keratinocytes for up to 60 days, potentially offering new approaches for DEB treatment.

This study suggests that decreased levels of dihydroceramide in hair may serve as a biomarker for the progression of alopecia.

Ceramide may help delay hair aging by restoring stressed hair cells.

This study found that deleting ceramide synthase 4 in skin epidermis stem cells disrupts hair follicle and skin barrier function, leading to immune responses similar to atopic dermatitis, due to imbalances in lipid composition affecting differentiation.

This study found that synthetic ceramide shampoo improved dandruff and erythema while reducing water loss when compared to control in a group of 20 subjects over four weeks.

This study found that mice lacking alkaline ceramidase 1 with elevated skin ceramide levels showed disrupted skin homeostasis, including altered hair follicle structures, increased water loss, and a hypermetabolism phenotype.

This study suggests that synthetic ceramides may promote hair growth by inducing proliferation of human dermal papilla cells through modulation of Wnt/β-catenin and BMP2/4 signaling pathways.

This study suggests that ceramide may help maintain hair follicles under stress by modulating growth factor pathways in senescence-induced dermal papilla cells.

The document lists various dermatology topics, treatments, and diagnostic methods.

This study observed that inducible deletion of the Ugcg gene in mouse epidermis led to a significant reduction in GlcCers and epidermal POS-Cers, causing impaired skin barrier function and delayed wound healing.

This study found that liposomes coated with cationic polymers, chitosan and Eudragit EPO, showed improved physicochemical stability and enhanced skin diffusion of aciclovir and minoxidil compared to uncoated liposomes.

This study found that nobiletin-loaded vesicles effectively restored skin condition in a mouse model of skin cancer, suggesting they are a promising treatment delivery system.

This study analyzed the lipid composition of mouse hair, focusing on sphingolipids, and found significant differences in ceramides, glucosylceramides, and sphingomyelins between hair follicles and hair shafts.

In this study, the researchers found that deleting ceramide synthase 4 in the skin's epidermis alters stem cell differentiation, disrupting hair follicle structure and barrier function, potentially leading to immune responses similar to atopic dermatitis.

This study found no significant differences in phosphatide distribution between normal and cancerous mouse epidermis during different stages of growth, despite variations in total phosphatide levels.

In this study, a high-fat, high-cholesterol diet in atherosclerotic mice led to skin inflammation and hair problems, which could be reversed by inhibiting glycosphingolipid synthesis.

This case report describes a 22-year-old female with pseudoglucagonoma syndrome, where necrolytic migratory erythema resolved after treatment with topical steroids, emollients, and intravenous protein infusions, despite normal glucagon levels and absence of a glucagon-secreting tumor.

This review highlights the limited research on sebocyte lipid droplets and their proteins despite their role in sebocyte differentiation and potential involvement in skin diseases like acne and alopecia, and reports no new results.

In this study, it was observed that NIPAL4 mutations linked to autosomal recessive congenital ichthyosis lead to abnormal skin barrier function due to cytotoxic effects disrupting lipid structure and organization, which topical treatments only partially ameliorated.
