Abstract
Avocado, superfood, contains a variety of essential nutrients and phytochemicals. The purpose of this study was to explore whether avocado could modulate skin inflammation in vivo. We elucidated the pharmacological effects of avocado on compound 48/80- or histamine-induced scratching behaviors and 2, 4-dinitrochlorobenzene (DNCB)-induced atopic dermatitis (AD)-like skin lesions in mice. Additionally, we investigated the anti-inflammatory activity of avocado and its underlying mechanism including its effect on the expression levels of inflammatory-related genes and nuclear factor-κB (NF-κB) in DNCB-induced AD-like skin lesions. The findings of this study demonstrate that avocado attenuated AD-clinical symptoms including itching, eczematous, erythema and dryness and histamine levels in mice. Moreover, avocado suppressed both inflammatory cytokines expression as well as NF-κB and caspase-1 activation in AD-like skin lesions in mice. Taken together, these results demonstrate that avocado may be a potential candidate for treating skin inflammatory diseases like AD.
