Targeting the transferrin receptor for brain drug delivery

Area of Science:

• Neuroscience
• Pharmacology
• Biotechnology

Background:

• The blood-brain barrier (BBB) severely restricts the delivery of therapeutics to the central nervous system.
• Efficient drug delivery to the brain is critical for treating neurological disorders.
• Current strategies often struggle to bypass the BBB's protective functions.

Purpose of the Study:

• To review the role of the transferrin receptor (TfR) as a target for enhancing brain drug delivery.
• To explore historical and recent advancements in TfR-mediated drug delivery strategies.
• To assess the clinical potential of TfR-targeted therapeutics for CNS diseases.

Main Methods:

• Literature review of studies investigating TfR function at the BBB.
• Analysis of historical and contemporary TfR-targeting approaches for drug delivery.
• Evaluation of preclinical and clinical evidence for TfR-targeted medicines.

Main Results:

• The transferrin receptor (TfR) is a well-established target for facilitating drug transport across the BBB.
• Various TfR-targeting strategies have been developed, demonstrating successful brain penetration.
• Recent evidence highlights the efficacy and clinical promise of TfR-targeted therapies.

Conclusions:

• The TfR represents a viable and effective target for overcoming BBB limitations in drug delivery.
• TfR-mediated drug delivery holds significant potential for developing novel treatments for brain disorders.
• Further research and clinical translation of TfR-targeted medicines are warranted.
