ROS Regulation in CNS Disorder Therapy: Unveiling the Dual Roles of Nanomedicine

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Neuroscience

Background:

• The blood-brain barrier (BBB) restricts drug delivery to the brain, hindering effective treatment of neurological disorders.
• Reactive oxygen species (ROS) are implicated in the pathogenesis of brain tumors and neurodegenerative diseases (NDDs).
• Targeting ROS presents a therapeutic strategy for managing brain diseases.

Purpose of the Study:

• To review the mechanisms of nanomedicine crossing the BBB.
• To summarize ROS-modulating nanomedicine strategies for brain diseases.
• To discuss future directions in nanomedicine for brain disorder treatment.

Main Methods:

• Review of literature on BBB structure, function, and nanomedicine transport mechanisms.
• Analysis of studies utilizing nanomedicines for ROS modulation in brain diseases.
• Discussion of photodynamic therapy (PDT), chemodynamic therapy (CDT), and sonodynamic therapy (SDT) approaches.

Main Results:

• Nanomedicines demonstrate potential for BBB penetration and targeted delivery to brain lesions.
• ROS production via PDT, CDT, and SDT shows promise for brain tumor treatment.
• ROS depletion strategies are being explored for neurodegenerative disease management.
• Nanomedicine-based ROS management offers a dual approach for brain diseases.

Conclusions:

• Nanomedicines are valuable tools for enhancing brain disease diagnosis and treatment.
• Targeting ROS through nanomedicine provides a promising therapeutic avenue for brain disorders.
• Further research into nanomedicine design and ROS modulation is crucial for clinical translation.
