Lignans from rattan stems suppresses primary Aβ-induced microglia activation via NF-κB/MAPK signaling pathway.

Microglia cells play important roles in neurodegenerative diseases for clearing amyloid-β and reducing the occurrence of inflammation. In this study, the neuroinflammatory effect and the mechanism of lignans from rattan stems (rsSCH-L) were evaluated by Aβ-induced primary microglia cell model. The results have shown that rsSCH-L could reduce the levels of pro-inflammatory cytokines, including IL-1β, TNF-α and NO. Moreover, rsSCH-L suppressed the phosphorylations of NF-κB and IκBα as well as p38, JNK and ERK proteins in Aβ-induced microglia cells. Taken together, rsSCH-L could attenuate microglia cells from neuroinflammation by activating the NF-κB/MAPK signaling pathway.
