Lysosphingolipids in ceramide-deficient skin lipid models by Georgios Paraskevopoulos, Lukáš Opálka, Andrej Kováčik, Anna Paraskevopoulou, Eleni Panoutsopoulou, Irene Sagrafena, Petra Pullmannová, Robert Čáp, Kateřina Vávrová

“…In lipid models containing isolated human stratum corneum ceramides, reducing ceramides by ≥ 30% significantly increased permeability to four markers, likely due to loss of long-periodicity phase (LPP) lamellae and phase separation within the lipid matrix, as revealed by X-ray diffraction and infrared spectroscopy. However, when the missing ceramides were replaced by lysosphingolipids and FFAs, no further increase in permeability was observed. …”
