Anti-Neuroinflammatory Effects of Fucoxanthin via Inhibition of Akt/NF-κB and MAPKs/AP-1 Pathways and Activation of PKA/CREB Pathway in Lipopolysaccharide-Activated BV-2 Microglial Cells.


PMID 27933547

Abstract

Microglia play a critical role in controlling the homeostasis of the brain, but over-activated microglia secrete pro-inflammatory mediators and cytokines, which induce neuronal cell death. Fucoxanthin (Fx), a marine carotenoid, has demonstrated a variety of beneficial health effects. Despite accumulating evidence supporting the immune-modulating effects of Fx in vitro, the underlying signaling pathways remain unknown. In the present study, Fx dose-dependently inhibited the secretion of lipopolysaccharide (LPS)-induced pro-inflammatory mediators including interleukin (IL)-6, tumor necrosis factor (TNF)-α, reactive oxygen species (ROS), prostaglandin (PG) E
