What is it about?
This paper is about the emerging use of exosomes as advanced nanomedicine platforms for the treatment of neurological disorders. It reviews how naturally derived exosomes can transport therapeutic molecules across biological barriers and how they can be engineered to improve the delivery of drugs, proteins, RNA, and other bioactive cargos to the nervous system. The paper particularly focuses on the mechanisms underlying exosome-mediated therapeutic effects, strategies for engineering and targeting exosomes, and their potential applications in neurological diseases. It also discusses the major translational challenges—including cargo loading, targeting efficiency, production, characterization, safety, scalability, and clinical translation—thereby connecting the biological properties of exosomes with their potential development as next-generation therapeutic delivery systems. The article is authored by Nidhi Singh, Lahanya Guha, and Alka Kumari and was published in Therapeutic Delivery in 2026.

Why is it important?
This paper is important because it highlights exosome-based nanomedicine as a promising next-generation approach for treating neurological disorders, addressing a major challenge in drug delivery: the efficient and targeted transport of therapeutic cargo to the brain. By bringing together exosome biology, engineering strategies, and therapeutic applications, the review demonstrates how exosomes can serve not only as biocompatible carriers for drugs, proteins, and nucleic acids but also as biologically active systems capable of influencing neuroinflammation, neuronal survival, regeneration, and disease-associated pathways. In my view, its major significance lies in connecting advances in nanotechnology with the complex biology of neurological diseases while critically emphasizing challenges such as targeting specificity, cargo loading, scalability, safety, standardization, and clinical translation. Thus, the paper provides a useful framework for moving exosome-based therapeutics from promising experimental platforms toward more precise and clinically translatable interventions for neurological disorders.
Perspectives
From my perspective, this paper is important because it provides a comprehensive and timely overview of exosome-based nanomedicine as an emerging therapeutic strategy for neurological disorders, bringing together the biological mechanisms, engineering approaches, and translational potential of extracellular vesicles. By examining how exosomes can naturally cross biological barriers, deliver functional molecules, modulate neuroinflammation, influence neuronal survival and regeneration, and be engineered for targeted drug and gene delivery, the review highlights their potential to overcome several limitations of conventional therapeutics in neurological diseases. I particularly consider this work valuable because it connects fundamental exosome biology with advances in nanomedicine and precision delivery, while also critically highlighting challenges related to cargo loading, targeting specificity, scalability, characterization, safety, and clinical translation. Overall, the paper presents exosome-based systems not simply as drug carriers, but as biologically active and engineerable therapeutic platforms with considerable potential for next-generation treatment of complex neurological disorders.
