July 2018 in “Scientific Reports” 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.
January 2024 in “bioRxiv (Cold Spring Harbor Laboratory)” 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.

January 2025 in “The Journal of Cell Biology” 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 explored the structure and function of lipocalin prostaglandin D synthase, revealing its dual role in substrate catalysis and as a lipophilic ligand carrier, potentially informing future drug delivery design.
