Kidney-targeted nanoplatforms: Strategies and applications

Area of Science:

• Biomedical Engineering
• Nanotechnology
• Nephrology

Background:

• Renal diseases affect 850 million globally, causing significant morbidity and mortality.
• Current treatments face challenges in balancing efficacy with systemic toxicity.
• Engineered nanoplatforms present a novel approach for targeted renal therapeutics.

Purpose of the Study:

• To review the principles of renal targeting for nanomedicines.
• To explore structure-function relationships governing nanoparticle delivery to the kidney.
• To highlight the potential of nanotherapeutics in managing kidney diseases.

Main Methods:

• Review of preclinical evidence on nanotherapeutics for kidney diseases.
• Analysis of passive targeting mechanisms (particle size, charge, shape, density).
• Examination of active targeting strategies (receptor-ligand interactions).

Main Results:

• Nanoplatforms can deliver therapeutics to specific kidney regions, enhancing efficacy and reducing side effects.
• Nephrotropic mechanisms for nanoplatforms differ from conventional nanotherapeutics.
• Physicochemical properties significantly influence nanoparticle biodistribution and targeting in the kidney.

Conclusions:

• Nanotherapeutics hold significant promise for improved clinical management of kidney diseases.
• Precise kidney-specific delivery requires a deep understanding of renal targeting principles.
• Further research into nanoplatform design is essential for biosafety and therapeutic success.
