Quercetin protective potential against nanoparticle-induced adverse effects.

Area of Science:

• Nanotechnology and Environmental Health
• Natural Product Chemistry
• Toxicology

Background:

• Nanoparticles (NPs) are increasingly used, raising health and environmental concerns due to potential toxicity.
• NP toxicity mechanisms involve inflammation and oxidative stress, influenced by NP characteristics (size, shape, charge, chemistry).
• The natural flavonoid quercetin possesses antioxidant and anti-inflammatory properties, suggesting potential protective effects.

Purpose of the Study:

• To review existing literature on quercetin's protective effects against NP-induced toxicity.
• To highlight quercetin's therapeutic benefits and mechanisms of action in mitigating NP toxicity.
• To provide insights into the safer application of NPs.

Main Methods:

• Literature review of in vitro and in vivo studies.
• Analysis of quercetin's effects on NP-induced oxidative stress and inflammation.
• Evaluation of quercetin's impact on cellular function and tissue integrity.

Main Results:

• Quercetin demonstrates effectiveness in counteracting NP-induced toxicity.
• It alleviates oxidative stress, inflammation, and cellular damage caused by various NPs.
• Studies show quercetin preserves cellular function, modulates apoptosis, and maintains tissue integrity.

Conclusions:

• Quercetin shows significant therapeutic potential against NP-induced toxicity.
• Its antioxidant and anti-inflammatory actions are key mechanisms of protection.
• Findings support quercetin as a natural agent for safer NP use in daily applications.
