Exploring the Connection Between Nanomaterials and Neurodegenerative Disorders

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Neuroscience

Background:

• Nanomaterials (NMs) are crucial in drug delivery and tissue engineering.
• Nanoparticles (NPs) can induce reactive oxygen species (ROS) and trigger autophagy within cells.
• Alzheimer's disease (AD) currently lacks effective treatments, highlighting the need for novel therapeutic strategies.

Purpose of the Study:

• To review the role of nanomaterials in delivering bioactive compounds across the blood-brain barrier (BBB).
• To emphasize the significance of nanoparticle (NP) shape in siRNA delivery for central nervous system (CNS) disorders.
• To explore the application of NMs in cancer treatments and overcoming the BBB limitations.

Main Methods:

• Review of current literature on nanomaterial applications in drug delivery.
• Analysis of NP-induced ROS generation and autophagy.
• Examination of NP shape influence on gene silencing efficacy.
• Investigation of strategies for crossing the BBB and BBTB.

Main Results:

• Nanomaterials offer a promising approach for targeted drug delivery, especially across the BBB.
• The shape of siRNA-loaded NMs is critical for efficient gene delivery and suppression in the CNS.
• Combined NPs can effectively induce autophagy, a cellular process for maintaining ROS balance.

Conclusions:

• Nanomaterials represent a significant advancement for treating CNS disorders like AD and brain cancers.
• Tailoring NM shape is essential for optimizing therapeutic efficacy in targeted drug delivery.
• Further research into NMs can overcome the challenges posed by the BBB for brain-specific treatments.
