Abstract
Parkinson's disease (PD) is a chronic neurological disorder that is identified by a characteristic combination of symptoms such as bradykinesia, resting tremor, rigidity, and postural instability. It is the second most common neurodegenerative disease after Alzheimer's disease and is characterized by the progressive loss of dopamine-producing neurons in the brain. Currently, available treatments for PD are symptomatic and do not prevent the disease pathology. There is growing interest in developing disease-modifying therapy that can reduce disease progression and improve patients' quality of life. One of the promising therapeutic approaches under evaluation is gene therapy utilizing a viral vector, adeno-associated virus (AAV), to deliver transgene of interest into the central nervous system (CNS). Preclinical studies in small animals and nonhuman primates model of PD have shown promising results utilizing the gene therapy that express glial cell line-derived neurotrophic factor (GDNF), cerebral dopamine neurotrophic factor (CDNF), aromatic L-amino acid decarboxylase (AADC), and glutamic acid decarboxylase (GAD). This study provides a comprehensive review of the current state of the above-mentioned gene therapies in various phases of clinical trials for PD treatment. We have highlighted the rationale for the gene-therapy approach and the findings from the preclinical and nonhuman primates studies, evaluating the therapeutic effect, dose safety, and tolerability. The challenges associated with gene therapy for heterogeneous neurodegenerative diseases, such as PD, have also been described. In conclusion, the review identifies the ongoing promising gene therapy approaches in clinical trials and provides hope for patients with PD.
期刊介绍:
Neurological Sciences is intended to provide a medium for the communication of results and ideas in the field of neuroscience. The journal welcomes contributions in both the basic and clinical aspects of the neurosciences. The official language of the journal is English. Reports are published in the form of original articles, short communications, editorials, reviews and letters to the editor. Original articles present the results of experimental or clinical studies in the neurosciences, while short communications are succinct reports permitting the rapid publication of novel results. Original contributions may be submitted for the special sections History of Neurology, Health Care and Neurological Digressions - a forum for cultural topics related to the neurosciences. The journal also publishes correspondence book reviews, meeting reports and announcements.
