Gene therapy methods are increasingly used to model Parkinson's disease (PD) in animals in an effort to test experimental therapeutics within a more relevant context to disease pathophysiology and neuropathology. We have detailed several criteria that are critical or advantageous to accurately modeling PD in a murine model or in a nonhuman primate. Using these criteria, we then evaluate approaches made to model PD using viral vectors to date, including both adeno-associated viruses and lentiviruses. Lastly, we comment on the consideration of aging as a critical factor for modeling PD.

Nutritional epidemiology aims to link dietary exposures to chronic disease, but the instruments for evaluating dietary intake are inaccurate. One way to identify unreliable data and the sources of errors is to compare estimated intakes with the total energy expenditure (TEE). In this study, we used the International Atomic Energy Agency Doubly Labeled Water Database to derive a predictive equation for TEE using 6,497 measures of TEE in individuals aged 4 to 96 years.

NMDAR antagonists, such as memantine and ketamine, have shown efficacy in treating neurodegenerative diseases and major depression. The mechanism by which these drugs correct the aforementioned diseases is still unknown. Our study reveals that these antagonists significantly enhance 20S proteasome activity, crucial for degrading intrinsically disordered, oxidatively damaged, or misfolded proteins, factors pivotal in neurodegenerative diseases like Alzheimer's and Parkinson's.

Neurodegenerative diseases, such as Alzheimer's disease, Parkinson's disease, and Huntington disease, pose serious threats to human health, leading to substantial economic burdens on society and families. Despite extensive research, the underlying mechanisms driving these diseases remain incompletely understood, impeding effective diagnosis and treatment. In recent years, growing evidence has highlighted the crucial role of oxidative stress in the pathogenesis of various neurodegenerative diseases.

Aggregation of alpha-synuclein (αsyn) plays an integral role in Parkinson's disease (PD) and Dementia with Lewy bodies (DLB). 14-3-3θ is a highly expressed brain protein with chaperone-like activity that regulates αsyn folding. 14-3-3θ overexpression reduces αsyn aggregation, transmission between cells, and neuronal loss, while 14-3-3 inhibition promotes αsyn pathology.

Parkinson's Disease (PD) is a multisystem disorder in which dysregulated neuroimmune crosstalk and inflammatory relay via the gut-blood-brain axis have been implicated in PD pathogenesis. Although alterations in circulating inflammatory cytokines and reactive oxygen species (ROS) have been associated with PD, no biomarkers have been identified that predict clinical progression or disease outcome. Gastrointestinal (GI) dysfunction, which involves perturbation of the underlying immune system, is an early and often-overlooked symptom that affects up to 80 % of individuals living with PD.
