Recently we have demonstrated that needle-like cationic cellulose nanocrystals (CNC-AEMA2) evoke immunological responses through NLRP3 inflammasome/IL-1β inflammatory pathway. In this study we demonstrated that curcumin, a naturally occurring polyphenolic compound isolated from Curcuma longa (Zingiberaceae), was able to suppress, at least in part, this immunological response, as observed by diminished IL-1β secretion in CNC-AEMA2-stimulated macrophages primed with LPS. Curcumin is a well-known antioxidant and anti-inflammatory natural compound and in addition to acting as "scavenger" of reactive oxygen species (ROS), it can also upregulates antioxidant enzymes...

Turmeric (Curcuma longa) is a widely used spice that has various biological effects, and aqueous extracts of turmeric exhibit potent antioxidant activity and anti-inflammatory activity. Bisacurone, a component of turmeric extract, is known to have similar effects. Oxidative stress and inflammatory cytokines play an important role in ethanol-induced liver injury. This study was performed to evaluate the influence of a hot water extract of C. longa (WEC) or bisacurone on acute ethanol-induced liver injury. C57BL/6 mice were orally administered WEC (20 mg/kg body weight; BW) or bisacurone (60 µg/kg BW) at 30 min before a single dose of ethanol was given by oral administration (3·0 g/kg BW)...
