Anti-inflammatory effect of fucoidan extracted from Ecklonia cava in zebrafish model

► This study was designed to assess in vivo anti-inflammatory effect of fucoidan. ► Fucoidan of Ecklonia cava alleviated inflammation in tail-cutting-induced zebrafish model. ► Fucoidan exhibited anti-inflammatory activities in LPS-stimulated zebrafish model. ► Fucoidan has a protective effect against LPS-induced toxicity in zebrafish model.
