Targeted therapeutic strategies for the kidney

INTRODUCTION: Kidney diseases impose a significant burden with high incidence and mortality rates. Current treatment options for kidney diseases are limited, necessitating urgent development of novel and effective therapeutic strategies to delay or reverse disease progression. Targeted therapies for the kidney hold promise in significantly enhancing treatment outcomes, offering hope to patients afflicted with renal disorders. AREAS COVERED: This review summarized advances in kidney-targeted therapies including genes, peptides and proteins, cell-based, nanoparticles, and localized delivery routes. We also explored the potential clinical applications, prospects, and challenges of targeted therapies for renal disorders. EXPERT OPINION: Advances in targeted therapies for renal conditions have enhanced therapeutic outcomes. Clinical application of kidney-targeted therapies is currently limited by renal structure and the scarcity of robust biomarkers. Bridging the gap from basic and pre-clinical research targeting the kidney to achieving clinical translation remains a formidable challenge.
