The polysaccharide from Camellia oleifera fruit shell enhances immune responses via activating MAPKs and NF-B signaling pathways in RAW264.7 macrophages

Background: Macrophage plays an important role in innate immune responses by secreting immune molecules and phagocytosis. Camellia oleifera fruit shell, accounting for approximately 60% weight of the single C. oleif- era fruit, is rich in polysaccharides and has several biological activities such as anti-oxidation, lipid regulation and anticancer. However, the immunomodulatory activity of the polysaccharide from C. oleifera fruit shells (CPS) has not been reported. Objective: This study aimed...
