The anthraquinones (AQs) and derivatives are widely distributed in nature, including plants, fungi, and insects, with effects of anti-inflammation and anti-oxidation, antibacterial and antiviral, anti-osteoporosis, anti-tumor, etc. Inflammation, including acute and chronic, is a comprehensive response to foreign pathogens under a variety of physiological and pathological processes. AQs could attenuate symptoms and tissue damages through anti-inflammatory or immuno-modulatory effects.

Focus on the role of mitochondria in NLRP3 inflammasome activation: A prospective target for the treatment of ischemic stroke (Review).

Post‑ischemic neuroinflammation induced by the innate local immune response is a major pathophysiological feature of cerebral ischemic stroke, which remains the leading cause of mortality and disability worldwide. NLR family pyrin domain containing (NLRP)3 inflammasome crucially mediates post‑ischemic inflammatory responses via its priming, activation and interleukin‑1β release during hypoxic‑ischemic brain damage. Mitochondrial dysfunctions are among the main hallmarks of several brain diseases, including ischemic stroke.
