The impact of recent advances in lipidomics and redox lipidomics on dermatological research.

Free Radic Biol Med 2019 Apr 17. Epub 2019 Apr 17.

Department of Dermatology, Medical University of Vienna, Austria; Christian Doppler Laboratory for the Biotechnology of Skin Aging, Vienna, Austria.

Dermatological research is a major beneficiary of the rapidly developing advances in lipid analytic technology and of bioinformatic tools which help to decipher and interpret the accumulating big lipid data. At its interface with the environment, the epidermis develops a blend of lipids that constitutes the epidermal lipid barrier, essential for the protection from water loss and entry of dangerous noxae. Apart from their structural role in the barrier, novel intra- and inter-cellular signaling functions of lipids and their oxidation products have been uncovered in most cutaneous cell types over the last decades, and the discovery rate has been boosted by the advent of high resolution and -throughput mass spectrometric techniques.

Sunscreen or simulated sweat minimizes the impact of acute ultraviolet radiation on cutaneous microvascular function in healthy humans.

Exp Physiol 2019 Apr 20. Epub 2019 Apr 20.

Department of Kinesiology, The Pennsylvania State University, University Park, PA, 16802.

New Findings: What are the central questions of this study? Are UVR-induced increases in skin blood flow independent of skin erythema? Does broad-spectrum UVR exposure attenuate NO-mediated cutaneous vasodilation, and does sunscreen or sweat modulate this response? What are the main findings and their importance? Erythema and vascular responses to UVR are temporally distinct, and sunscreen prevents both responses. UVR exposure attenuates NO-mediated vasodilation in the cutaneous microvasculature; sunscreen or simulated sweat on the skin attenuate this response. Sun over-exposure may elicit deleterious effects on human skin that are separate from sunburn, and sunscreen or sweat on the skin may provide protection. Read More

Co-Delivery of M2e Virus-Like Particles with Influenza Split Vaccine to the Skin Using Microneedles Enhances the Efficacy of Cross Protection.

Pharmaceutics 2019 Apr 18;11(4). Epub 2019 Apr 18.

Institute for Biomedical Sciences, Georgia State University, Atlanta, GA 30303, USA.

It is a high priority to develop a simple and effective delivery method for a cross-protective influenza vaccine. We investigated skin immunization by microneedle (MN) patch with human influenza split vaccine and virus-like particles containing heterologous M2 extracellular (M2e) domains (M2e5x virus-like particles (VLP)) as a cross-protective influenza vaccine candidate. Co-delivery of influenza split vaccine and M2e5x VLP to the skin by MN patch was found to confer effective protection against heterosubtypic influenza virus by preventing weight loss and reducing lung viral loads.

Novel taxonomy-independent deep learning microbiome approach allows for accurate classification of different forensically relevant human epithelial materials.

Forensic Sci Int Genet 2019 Apr 4;41:72-82. Epub 2019 Apr 4.

Department of Genetic Identification, Erasmus MC University Medical Center Rotterdam, Rotterdam, the Netherlands. Electronic address:

Correct identification of different human epithelial materials such as from skin, saliva and vaginal origin is relevant in forensic casework as it provides crucial information for crime reconstruction. However, the overlap in human cell type composition between these three epithelial materials provides challenges for their differentiation and identification when using previously proposed human cell biomarkers, while their microbiota composition largely differs. By using validated 16S rRNA gene massively parallel sequencing data from the Human Microbiome Project of 1636 skin, oral and vaginal samples, 50 taxonomy-independent deep learning networks were trained to classify these three tissues.

A newly developed means of HPLC-fluorescence analysis for predicting the skin sensitization potential of multi-constituent substances using ADRA.

Toxicol In Vitro 2019 Apr 16. Epub 2019 Apr 16.

Safety Evaluation Centre, Ecology & Quality Management Division, CSR Division, FUJIFILM Corporation, 210 Nakanuma, Minamiashigara-shi, Kanagawa, Japan.

The Amino acid Derivative Reactivity Assay (ADRA) is an in chemico alternative to animal testing for skin sensitization potential, in which measurements of multi-constituent solutions were sometimes affected by co-elution with nucleophilic reagents. So, we established a means of using fluorescence detection and verified the utility of a newly developed ADRA-fluorescence detection (ADRA-FL) test method. We tested three types of plant extracts-aloe, green tea, and licorice-and although unable to quantify nucleophilic reagents using ultraviolet detection due to co-elution of multiple components, the use of fluorescence detection enabled us to detect nucleophilic reagents selectively and predict each of the extract solutions to be sensitizers.
