Advancing Alzheimer’s disease therapy through engineered exosomal Macromolecules

Exosomes are a subject of continuous investigation due to their function as extracellular vesicles (EVs) that significantly contribute to the pathophysiology of certain neurodegenerative disorders (NDD), including Alzheimer’s disease (AD). Exosomes have shown the potential to carry both therapeutic and pathogenic materials; hence, researchers have used exosomes for medication delivery applications. Exosomes have reduced immunogenicity when used as natural drug delivery vehicles. This guarantees the efficient delivery of the medication without causing significant side reactions. Exosomes have lately enabled the potential for drug delivery in AD, along with promising future therapeutic uses for the detection of neurodegenerative disorders. Furthermore, exosomes have been examined for their prospective use in illness diagnosis and prediction before the manifestation of symptoms. This review will document prior studies and will concentrate on the rationale behind the substantial potential of exosomes in the treatment of AD and their prospective use as a diagnostic and predictive tool for this condition.
