-Glucocerebrosidase activity in mammalian stratum corneum
Although previous studies have demonstrated a crucial role for the enzyme b -glucocerebrosidase (GlcCer’ase) in the final steps of membrane structural maturation in mammalian stratum cornuem (SC) and epidermal homeostasis, the precise in vivo localization of GlcCer’ase activity and protein is not known. Here, we developed a fluorogenic in situ assay on histologic sections (zymography) to elucid...
متن کاملbeta-Glucocerebrosidase activity in the stratum corneum of house sparrows following acclimation to high and low humidity.
Skin is an important avenue of water loss in terrestrial birds, so environmental conditions that necessitate water conservation should favor physiological mechanisms that reduce cutaneous water loss (CWL). Skin resistance to CWL is conferred by a barrier of lipid molecules located in the stratum corneum (SC), the outer layer of the epidermis. In mammals, SC barrier function depends on the conve...
متن کاملDesquamation in the stratum corneum.
To maintain a constant thickness of the stratum corneum the desquamation rate and the de novo production of corneocytes is delicately balanced. Using a plantar stratum corneum model we have obtained evidence that proteolysis is a central event in the desquamation process. A number of regulatory mechanisms for desquamation have been postulated based on our findings.
متن کاملStratum corneum dysfunction in dandruff
Dandruff is characterized by a flaky, pruritic scalp and affects up to half the world's population post-puberty. The aetiology of dandruff is multifactorial, influenced by Malassezia, sebum production and individual susceptibility. The commensal yeast Malassezia is a strong contributory factor to dandruff formation, but the presence of Malassezia on healthy scalps indicates that Malassezia alon...
متن کاملMechanical Properties of the Human Stratum Corneum: Hydration Effects on Graded Delamination of Human Stratum Corneum
Reinhold Dauskardt Stanford University, Professor Materials Sciences and Engineering The stratum corneum (SC) is the outermost layer of the skin. Its process of reneweal is regulated by various mechanisms, including chemical and structural gradients through the SC thickness. In this study, an in vitro mechanics approach for studying the delamination behavior of SC in the direction perpendicular...
