The Suppressive Effect of β-Glucan on the Production of Tumor Necrosis Factor-Alpha in BV2 Microglial Cells

Abstract

β-Glucan was recently shown to have the ability to enhance and stimulate the immune system in humans, but little is known about its the anti-inflammatory effects. We investigated the effect of β-glucan on the production of tumor necrosis factor-alpha (TNF-α), a major pro-inflammatory mediator, in lipopolysaccharide (LPS)-stimulated BV2 microglial cells. β-Glucan decreased the production and expression of TNF-α. In addition, it blocked LPS-stimulated activation of nuclear factor kappa B (NF-κB). Hence β-glucan might suppress LPS-stimulated TNF-α production by inhibiting NF-κB in BV2 microglial cells.
