The KEAP1-NRF2 System and Neurodegenerative Diseases

Area of Science:

• Neuroscience
• Molecular Biology
• Cellular Biology

Background:

• Central nervous system (CNS) diseases encompass neurodegenerative disorders like Alzheimer's and Parkinson's.
• The KEAP1-NRF2 system is a critical regulator of cellular stress responses and inflammation.
• Oxidative stress, inflammation, and proteostasis dysfunction are implicated in neurodegenerative diseases.

Purpose of the Study:

• To investigate the role of the KEAP1-NRF2 system in neurodegenerative diseases.
• To evaluate the therapeutic potential of targeting the KEAP1-NRF2 pathway for CNS disorders.

Main Methods:

• Review of existing literature on the KEAP1-NRF2 pathway and neurodegeneration.
• Analysis of studies involving NRF2 manipulation in animal models of CNS diseases.

Main Results:

• NRF2 (Nuclear factor erythroid 2-related factor 2) activation protects against CNS damage.
• NRF2 depletion exacerbates neurodegenerative symptoms, oxidative stress, and inflammation in mouse models.
• Targeting the KEAP1-NRF2 system demonstrates therapeutic benefits in preclinical models.

Conclusions:

• The KEAP1-NRF2 system is a crucial regulator of cellular defense mechanisms relevant to neurodegeneration.
• Modulating the KEAP1-NRF2 pathway represents a promising therapeutic strategy for treating CNS diseases.
• Dimethyl fumarate, an NRF2 activator, is clinically used for Multiple Sclerosis (MS), supporting this therapeutic avenue.
