Ganglioside GD1a suppresses LPS-induced pro-inflammatory cytokines in RAW264.7 macrophages by reducing MAPKs and NF-κB signaling pathways through TLR4.

Gangliosides, sialic acid-containing glycosphingolipids, have been considered to be involved in the development, differentiation, and function of nervous systems in vertebrates. However, the mechanisms for anti-inflammation caused by gangliosides are not clear. In this paper, we investigated the anti-inflammation effects of ganglioside GD1a by using RAW264.
