Urushiol-induced allergic contact dermatitis (ACD) is a chronic inflammatory skin disease in which skin barrier dysfunction leads to pruritus and eczematous lesions. ACD is triggered by immune imbalance. Aloe emodin is an anthraquinone derivative extracted from rhubarb, aloe and other traditional Chinese medicines. It has a wide range of pharmacological effects, including anti-inflammatory, anti-tumor, and anti-allergic effects. The purpose of our study was to demonstrate the effectiveness of aloe-emodin on urushiol-induced acute pruritus and allergic contact dermatitis. The results showed that urushiol could stimulate keratinocytes to release chemokines CXCL1, CXCL2, CCL2, TSLP, and TNF-α, which recruit or activate mast cells. Aloe-emodin treatment inhibited inflammatory-response-induced mast cell degranulation in skin lesions and suppressed the expression of inflammatory cytokines, such as interleukin-4, and interleukin-6. Therefore, the results indicate that aloe-emodin can improve urushiol-induced acute pruritus and allergic contact dermatitis in mice by inhibiting mast cell degranulation.
期刊介绍:
Immunology Letters provides a vehicle for the speedy publication of experimental papers, (mini)Reviews and Letters to the Editor addressing all aspects of molecular and cellular immunology. The essential criteria for publication will be clarity, experimental soundness and novelty. Results contradictory to current accepted thinking or ideas divergent from actual dogmas will be considered for publication provided that they are based on solid experimental findings.
Preference will be given to papers of immediate importance to other investigators, either by their experimental data, new ideas or new methodology. Scientific correspondence to the Editor-in-Chief related to the published papers may also be accepted provided that they are short and scientifically relevant to the papers mentioned, in order to provide a continuing forum for discussion.
