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.
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.
