Harnessing Endogenous Mechanisms for Targeted Drug Delivery explores the cutting-edge advancements in the world of targeted drug delivery leveraging human biological mechanisms. This essential guide addresses the urgent need to enhance the efficiency of drug delivery and foster safe and effective therapies, particularly for biological agents like proteins, peptides, and nucleic acid molecules. The book offers a comprehensive exploration of tissue- and cell-specific delivery methods, emphasizing endogenous or biological techniques that can be utilized to improve drug delivery. It identifies the challenges associated with delivering complex molecules and accessing hard-to-reach sites, and provides practical solutions through endogenous strategies. Topics such as exploiting disease-specific stimuli to enhance delivery efficiency, the role of plasma proteins in drug delivery, and the utilization of extracellular vesicles to boost delivery efficiency are presented. Harnessing Endogenous Mechanisms for Targeted Drug Delivery emphasizes the clinical and commercial translation of these techniques, making this book an ideal resource for researchers, clinicians, and anyone interested in the future of drug delivery.
