    Elucidation of the Synthetic Mechanism of Acylceramide, an Essential Lipid for Skin Barrier Function.
    Yakugaku Zasshi 2017 ;137(10):1201-1208
    Laboratory of Biochemistry, Faculty of Pharmaceutical Sciences, Hokkaido University.
    The primary function of the skin is to act as a permeability barrier that prevents water loss from inside the body and external invasion such as by pathogens, harmful substances, and allergens. Lipids play a critical role in skin barrier formation by forming multi-lamellar structures in the stratum corneum, the outermost cell layer of the epidermis. Ceramide, the backbone of sphingolipids, accounts for more than 50% of the stratum corneum lipids. Read More

    Omega-O-Acylceramides in Skin Lipid Membranes: Effects of Concentration, Sphingoid Base, and Model Complexity on Microstructure and Permeability.
    Langmuir 2016 Dec 23;32(48):12894-12904. Epub 2016 Nov 23.
    Faculty of Pharmacy, Charles University , Hradec Králové 500 05, Czech Republic.
    Omega-O-acylceramides (acylCer), a subclass of sphingolipids with an ultralong N-acyl chain (from 20 to 38 carbons, most usually 30 and 32 carbons), are crucial components of the skin permeability barrier. AcylCer are involved in the formation of the long periodicity lamellar phase (LPP, 12-13 nm), which is essential for preventing water loss from the body. Lower levels of acylCer and LPP accompany skin diseases, such as atopic dermatitis, lamellar ichthyosis, and psoriasis. Read More

    Defects in Stratum Corneum Desquamation Are the Predominant Effect of Impaired ABCA12 Function in a Novel Mouse Model of Harlequin Ichthyosis.
    PLoS One 2016 23;11(8):e0161465. Epub 2016 Aug 23.
    Department of Dermatology and Charles C. Gates Center for Regenerative Medicine, University of Colorado Anschutz Medical Campus, Aurora, CO, United States of America.
    Harlequin Ichthyosis is a severe skin disease caused by mutations in the human gene encoding ABCA12. Here, we characterize a novel mutation in intron 29 of the mouse Abca12 gene that leads to the loss of a 5' splice donor site and truncation of the Abca12 RNA transcript. Homozygous mutants of this smooth skin or smsk allele die perinatally with shiny translucent skin, typical of animal models of Harlequin Ichthyosis. Read More

    Genetics and prospective therapeutic targets for Sjögren-Larsson Syndrome.
    Expert Opin Orphan Drugs 2016 Apr 10;4(4):395-406. Epub 2016 Mar 10.
    Department of Pediatrics, University of Nebraska Medical Center, Omaha, NE, USA.
    Introduction: Sjögren-Larsson syndrome (SLS) is a rare neurocutaneous disease characterized by ichthyosis, spasticity, intellectual disability and a distinctive retinopathy. It is caused by inactivating mutations in ALDH3A2, which codes for fatty aldehyde dehydrogenase (FALDH) and results in abnormal metabolism of long-chain aliphatic aldehydes and alcohols. The potential disease mechanisms leading to symptoms include 1) accumulation of toxic fatty aldehydes that form covalent adducts with lipids and membrane proteins; 2) physical disruption of multi-lamellar membranes in skin and brain; 3) abnormal activation of the JNK cell signaling pathway; and 4) defective farnesol metabolism resulting in abnormal PPAR-α dependent gene expression.

    Two Cases of Autosomal Recessive Congenital Ichthyosis due to CYP4F22 Mutations: Expanding the Genotype of Self-Healing Collodion Baby.
    Pediatr Dermatol 2016 Mar-Apr;33(2):e48-51. Epub 2015 Dec 9.
    Department of Dermatology, Hospital Universitario Niño Jesús, Madrid, Spain.
    Collodion babies are born with a tight, shiny cast that sheds in a few weeks. After shedding, most patients will display features of autosomal recessive congenital ichthyosis (ARCI) later in life but in up to 10% of cases, the skin eventually becomes normal or only minimally involved, a phenotype called self-healing collodion baby (SHCB), which is considered as ARCI subtype in the 2010 consensus classification of congenital ichthyosis. The term self-improving collodion ichthyosis (SICI) has been proposed for these patients. Read More
