Challenges in Exploiting Human H Ferritin Nanoparticles for Drug Delivery: Navigating Physiological Constraints.

Area of Science:

• Biotechnology
• Nanomedicine
• Protein Engineering

Background:

• Ferritin nanoparticles are explored as drug delivery systems due to their biocompatibility, controlled size, and hollow structure for therapeutic agent encapsulation.
• Despite potential, clinical translation of ferritin-based nanocarriers is limited.

Purpose of the Study:

• To highlight the necessity of evaluating ferritin's pharmacokinetic properties for successful clinical application.
• To identify key challenges hindering the therapeutic use of ferritin nanoparticles.

Main Methods:

• Review of existing literature on ferritin nanoparticle drug delivery.
• Analysis of pharmacokinetic considerations including biodistribution, clearance, cellular trafficking, and immunogenicity.
• Identification of knowledge gaps in ferritin's in vivo behavior.

Main Results:

• Ferritin's physiological role and inherent organ accumulation (liver, spleen, kidneys) can cause off-target effects.
• Mechanisms of clearance, cellular trafficking, and immune response require further elucidation.
• Incomplete pharmacokinetic evaluation impedes clinical advancement.

Conclusions:

• Addressing ferritin's biodistribution, clearance, cellular uptake, and immunogenicity is essential for optimizing drug delivery.
• Comprehensive understanding of these physiological factors is key to realizing the full therapeutic potential of ferritin nanoparticles.
• Overcoming these challenges will facilitate the transition of ferritin nanomedicines from research to clinical practice.
