Novel Drug Delivery Technologies and Targets for Renal Disease

Area of Science:

• Nephrology and Pharmacology
• Biomedical Engineering and Drug Delivery Systems

Background:

• Acute and chronic kidney diseases pose a significant health burden due to high mortality and limited therapeutic options.
• The kidney's complex cellular and structural environment complicates strategies for protecting and recovering renal function post-injury.
• Current management relies primarily on supportive care and renal replacement therapies.

Purpose of the Study:

• To review the feasibility and limitations of drug delivery technologies for treating kidney diseases.
• To provide an update on the potential of advanced carriers for renal therapy.
• To discuss future directions for overcoming clinical translation hurdles.

Main Methods:

• Review of emerging preclinical evidence on drug delivery systems for renal applications.
• Analysis of various carriers including peptides, proteins, nanoparticles, liposomes, and extracellular vesicles.
• Examination of therapeutic cargo such as peptides, proteins, nucleic acids, and small molecules.

Main Results:

• Drug delivery systems demonstrate potential for precise renal uptake, extended circulation time, and targeted intraorgan biodistribution.
• These systems can protect therapeutic cargo, potentially improving efficacy for kidney disease treatment.
• Key challenges include drug solubility, toxicity, and suboptimal renal targeting, hindering clinical application.

Conclusions:

• Drug delivery technologies offer promising strategies to enhance the treatment of acute and chronic kidney diseases.
• Further research is needed to address current limitations and facilitate the clinical translation of these advanced renal therapies.
• Optimizing targeting and formulation will be crucial for realizing the full therapeutic potential in nephrology.
