Abstract
Mitochondrial activity is essential for the proper functioning of higher brain processes, and its impairment has been linked to a wide range of neurological disorders. Increasing evidence shows that under physiological and pathological conditions, mitochondria can be secreted into the extracellular environment to regulate various biological responses, including cellular bioenergetics. Today, the therapeutic modality known as “mitochondrial transplantation” has emerged as a cutting-edge and highly promising intervention for the promotion of cell and tissue regeneration. This innovative approach entails the replacement of dysfunctional mitochondria in the recipient organism with healthy, functional exogenous mitochondria, thereby aiming to restore cellular function and promote tissue repair and recovery. Several studies have demonstrated the beneficial effects of local or systemic administration of mitochondria on in vitro and in vivo models of brain diseases. We discuss the effect of mitochondrial transplantation in various brain diseases and highlight some critical issues. In this regard, we propose vesicles as a delivery system for both whole mitochondria and mitochondrial components to target cells in the central nervous system. Furthermore, the aim of this review is twofold: firstly, to emphasize the significance of brain mitochondrial transplantation, and secondly, to prompt the scientific community to consider the practical applications of brain mitochondrial transplantation. To this end, the text highlights the as yet unresolved issues and challenges that must be addressed and surmounted if this field is to progress. In conclusion, the authors express their support for the development of new potential therapies for mitochondrial diseases of the central nervous system.
期刊介绍:
With the rise in average human life expectancy, the impact of ageing and age-related diseases on our society has become increasingly significant. Ageing research is now a focal point for numerous laboratories, encompassing leaders in genetics, molecular and cellular biology, biochemistry, and behavior. Ageing Research Reviews (ARR) serves as a cornerstone in this field, addressing emerging trends.
ARR aims to fill a substantial gap by providing critical reviews and viewpoints on evolving discoveries concerning the mechanisms of ageing and age-related diseases. The rapid progress in understanding the mechanisms controlling cellular proliferation, differentiation, and survival is unveiling new insights into the regulation of ageing. From telomerase to stem cells, and from energy to oxyradical metabolism, we are witnessing an exciting era in the multidisciplinary field of ageing research.
The journal explores the cellular and molecular foundations of interventions that extend lifespan, such as caloric restriction. It identifies the underpinnings of manipulations that extend lifespan, shedding light on novel approaches for preventing age-related diseases. ARR publishes articles on focused topics selected from the expansive field of ageing research, with a particular emphasis on the cellular and molecular mechanisms of the aging process. This includes age-related diseases like cancer, cardiovascular disease, diabetes, and neurodegenerative disorders. The journal also covers applications of basic ageing research to lifespan extension and disease prevention, offering a comprehensive platform for advancing our understanding of this critical field.
