Nanoparticles-protein interaction: Role in protein aggregation and clinical implications

Area of Science:

• Biochemistry
• Nanotechnology
• Neuroscience

Background:

• Protein misfolding and aggregation are implicated in neurodegenerative diseases.
• Cellular chaperones normally assist protein folding, but failures lead to disease.
• Misfolded proteins can form aggregates like amyloid fibrils, causing fatal conditions.

Purpose of the Study:

• To review the role of nanoparticles in protein folding and neurodegenerative disease.
• To explore the formation and impact of the nanoparticle-protein corona.
• To highlight the therapeutic potential of nanoparticles in protein misfolding disorders.

Main Methods:

• Review of existing literature on protein misfolding, aggregation, and nanoparticle interactions.
• Analysis of nanoparticle-protein corona formation and its effect on protein conformation.
• Discussion of nanoparticle-mediated modulation of protein folding and aggregation.

Main Results:

• Nanoparticles can interact with proteins, forming a nanoparticle-protein corona.
• This corona can induce conformational changes in proteins, affecting their bio-reactivity.
• Nanoparticles show potential in promoting correct protein folding and preventing aggregation.

Conclusions:

• Nanoparticles offer a novel approach to manage protein misfolding and aggregation.
• The nanoparticle-protein interaction is key to their therapeutic potential in neurodegenerative disorders.
• Harnessing nanoparticle properties may lead to new strategies for treating protein misfolding diseases.
