Abstract
ABSTRACT
Taraxasterol (TAL) is a pentacyclic triterpenoid compound, which has anti-inflammatory effect. Cytotoxicity assay was used to determine the optimal concentration of TAL and positive control dipotassium glycyrrhizinate (DG), and the optimal dose of UVB. Experimental data indicate that TAL has scavenging activity against UVB radiation-induced intracellular reactive oxygen species (ROS) compared to UVB controls. The contents of skin barrier-related factors in the groups were detected by Enzyme-linked immunosorbent assay (ELISA), then ELISA and quantitative polymerase chain reaction (qPCR) were used to detect changes in the inflammatory factors, apoptosis factors, and gene levels in the groups. Therefore, TAL stabilised the levels of inflammation, apoptosis, and skin barrier-related factors by regulating Mitogen-activated protein kinases/nuclear factor-k-gene binding (MAPK/NF-κB) signalling pathways, such as jun-amino-terminal kinase (JNK), p38, extracellular signal-regulated kinase (ERK), and NF-κB. These results suggest that TAL repairs UVB-induced skin barrier damage by scavenging reactive oxygen species and regulating the MAPK/NF-κB signalling pathway.
期刊介绍:
Food and Agricultural Immunology is an international open access journal publishing original immunological research with applications in food, agricultural, environmental and veterinary science. Submissions describing the use of immunological techniques and methods are particularly welcomed.
The journal aims to expand our understanding of the interactions at the interface of food and immune systems including studies on:
-Development of diagnostic systems – all types of ligand-based assays, e.g. antibody, aptamer
-Application of ligand-based assays for the detection or identification of molecules of interest in food science, agricultural research, veterinary investigations and clinical systems relating to food allergy or sensitivity to agricultural chemicals
-Effects of food on the immune system
-Studies on allergy and allergic reactions
-Investigations into food allergies
-Development of allergen-free food systems
-Development of novel assay formats
-Applications of assay systems to the monitoring of food items in relation to safety and labelling
-Food quality issues, e.g. speciation, adulteration and contamination
-Comparisons between different analytical techniques
The journal publishes research and review articles and is essential reading for food scientists, immunologists and all those concerned with the interaction between food and immune systems.
