Nanodiamond-mediated delivery of microRNA-7 for the neuroprotection of dopaminergic neurons by Yuping Han, Yue Yao, Xinyi Wen, Hao Wang, Shurong Li, Bingyin Su

“…Parkinson’s disease (PD) is a neurodegenerative disorder characterized by the gradual loss of dopaminergic neurons in the substantia nigra and the accumulation of α-synuclein aggregates known as Lewy bodies. MicroRNA-7 (miR-7) targets the gene SNCA, which encodes α-synuclein, reducing its expression and alleviating neuronal damage in PD. …”

Therapeutic Application of rTMS in Atypical Parkinsonian Disorders by Chrysi Petsani, Athina-Maria Aloizou, Vasileios Siokas, Lambros Messinis, Eleni Peristeri, Christos Bakirtzis, Grigorios Nasios, Efthimios Dardiotis

“…The terms atypical parkinsonian disorders (APDs) and Parkinson plus syndromes are mainly used to describe the four major entities of sporadic neuronal multisystem degeneration: progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), multiple system atrophy (MSA), and dementia with Lewy bodies (LBD). APDs are characterized by a variety of symptoms and a lack of disease modifying therapies; their treatment thus remains mainly symptomatic. …”

Neuropathology and Neurochemistry of Nonmotor Symptoms in Parkinson's Disease by Isidro Ferrer

“…Although there is a close relation between motor symptoms and the presence of Lewy bodies (LBs) and neurites filled with abnormal 𝛼-synuclein, other neurological alterations are independent of the amount of 𝛼-synuclein inclusions in neurons and neurites, thereby indicating that different mechanisms probably converge in the degenerative process. …”

Mitochondrial Dysfunction and α-Synuclein Synaptic Pathology in Parkinson’s Disease: Who’s on First? by Michela Zaltieri, Francesca Longhena, Marina Pizzi, Cristina Missale, PierFranco Spano, Arianna Bellucci

“…Its characteristic neuropathological features encompass the loss of dopaminergic neurons of the nigrostriatal system and the presence of Lewy bodies and Lewy neurites. These are intraneuronal and intraneuritic proteinaceous insoluble aggregates whose main constituent is the synaptic protein α-synuclein. …”

Blood Plasma of Patients with Parkinson’s Disease Increases Alpha-Synuclein Aggregation and Neurotoxicity by Peng Wang, Xin Li, Xuran Li, Weiwei Yang, Shun Yu

“…A pathological hallmark of Parkinson’s disease (PD) is formation of Lewy bodies in neurons of the brain. This has been attributed to the spread of α-synuclein (α-syn) aggregates, which involves release of α-syn from a neuron and its reuptake by a neighboring neuron. …”

Gut–brain axis and environmental factors in Parkinson’s disease: bidirectional link between disease onset and progression by Soo Jung Park, Kyung Won Kim, Eun Jeong Lee

“…Parkinson’s disease has long been considered a disorder that primarily affects the brain, as it is defined by the dopaminergic neurodegeneration in the substantia nigra and the brain accumulation of Lewy bodies containing α-synuclein protein. In recent decades, however, accumulating research has revealed that Parkinson’s disease also involves the gut and uncovered an intimate and important bidirectional link between the brain and the gut, called the “gut–brain axis.” …”

Resting State fMRI: A Valuable Tool for Studying Cognitive Dysfunction in PD by Kai Li, Wen Su, Shu-Hua Li, Ying Jin, Hai-Bo Chen

“…In this review, we summarize rs-fMRI studies on cognitive function in PD and discuss the strong potential of rs-fMRI in this area. rs-fMRI can help reveal the pathophysiology of cognitive symptoms in PD, facilitate early identification of PD patients with cognitive impairment, distinguish PD dementia from dementia with Lewy bodies, and monitor and guide treatment for cognitive impairment in PD. …”
