Characterization and Therapeutic Potential of Curcumin-Loaded Cerium Oxide Nanoparticles for Interstitial Cystitis...

Area of Science:

• Biomedical Engineering
• Nanomedicine
• Urology

Background:

• Interstitial cystitis (IC) is a chronic inflammatory condition often linked to oxidative stress from reactive oxygen species (ROS).
• Antioxidants show therapeutic potential for IC, necessitating advanced delivery systems.

Purpose of the Study:

• To develop and evaluate curcumin-loaded cerium oxide nanoparticles (Cur-CONPs) as an antioxidant treatment for IC.
• To investigate the synergistic anti-inflammatory and antioxidant effects of combining curcumin with cerium oxide nanoparticles (CONPs).

Main Methods:

• In vitro assessment of antioxidant and anti-inflammatory properties of Cur-CONPs compared to CONPs.
• In vivo studies using a mouse model of IC to evaluate therapeutic efficacy.
• Analysis of micturition behavior, pain sensitivity, and inflammatory protein expression (IL-6, IL-1β, TNF-α, Cox2).

Main Results:

• Cur-CONPs demonstrated enhanced antioxidant and anti-inflammatory capabilities compared to CONPs alone.
• Mice with IC treated with Cur-CONPs showed improved urinary function and reduced pain sensitivity.
• Cur-CONP treatment led to decreased expression of key inflammatory markers.

Conclusions:

• Cur-CONPs represent a promising novel therapeutic strategy for IC by combining sustained antioxidant release from CONPs with the acute anti-inflammatory action of curcumin.
• This synergistic approach effectively targets oxidative stress and inflammation in IC.
