Background Stratum corneum lipids, particularly ceramides, are important components of the epidermal permeability barrier that are decreased in atopic dermatitis and aged skin. Objectives We investigated the effects of nicotinamide, one of the B vitamins, on biosynthesis of sphingolipids, including ceramides and other stratum corneum lipids, in cultured normal human keratinocytes, and on the epidermal permeability barrier in vivo. Methods The rate of sphingolipid biosynthesis was measured by…

Ceramides metabolism and impaired epidermal barrier in cutaneous diseases and skin aging: focus on the role of the enzyme PNPLA1 in the synthesis of ω-O-acylceramides and its pathophysiological involvement in some forms of congenital ichthyoses
- Biology, MedicineOCL
- 2019
Data from patients with Autosomal Recessive Congenital Ichthyosis and a murine knock-out model showed that the enzyme PNPLA1 is essential for the last step of synthesis of omega-O-acylceramides, and treatments able to increase skin-ceramide levels could improve the epidermal barrier function in aged skin.
Ceramides and Skin Function
- BiologyAmerican journal of clinical dermatology
- 2003
The link between skin disorders and changes in barrier lipid composition, especially in ceramides, is difficult to prove, however, most skin disorders that have a diminished barrier function present a decrease in total ceramide content with some differences in the ceramide pattern.
Eucalyptus increases ceramide levels in keratinocytes and improves stratum corneum function
- BiologyInternational journal of cosmetic science
- 2012
The results indicate that the increased content of ceramides in the stratum corneum may underlie the therapeutic effect of the Eucalyptus extract and indicate the possibility that macrocarpal A is the key component that stimulates the synthesis of ceramide in the Stratum Corneum.

It is found that cultured human neonatal keratinocytes contain unusually high levels of serine-palmitoyl transferase activity, and that the substrate specificity of keratinocyte SPT may determine the base composition of epidermal sphingolipids.

UVB irradiation up-regulates serine palmitoyltransferase in cultured human keratinocytes.

It is demonstrated that CHKs respond to UVB by increasing sphingolipid synthesis, primarily through increases in both LCB2 mRNA and protein levels, leading to increased SPT activity, and suggested further that epidermis up-regulates sphingosine synthesis at both the mRNA andprotein levels in response toUVB.
Decreased level of ceramides in stratum corneum of atopic dermatitis: an etiologic factor in atopic dry skin?

Findings suggest that an insufficiency of ceramides in the stratum corneum is an etiologic factor in atopic dry skin.
Lipid content and lipid type as determinants of the epidermal permeability barrier.

A relationship between the total lipid content of the stratum corneum and barrier function is supported and removal of nonpolar species alone appears to cause only a modest level of barrier disruption, while removal of sphingolipids and free sterols leads to a more profoundlevel of barrier perturbation.
