Summary: This article investigates the mechanism by which dysregulation of autophagic pathways leads to the accumulation of abnormal proteins and damaged organdies in neurodegenerative disorders. The authors found that pathologic protein S-nitrosylation of p62 is a critical factor for autophagic inhibition and cell-to-cell spread.

Summary: Oxidative stress is important in the development of Parkinson's disease (PD). In this study, higher levels of the oxidative stress-induced DNA damage 8-oxodG were observed in the midbrain of PD patients. These patients also had a novel mutant form of the α-synuclein protein, which is associated with 8-oxodG. The findings suggest a possible link between TM-generated mutations of α-synuclein and the formation of Lewy bodies and PD pathogenesis.

Summary: Parkinson's disease is a neurodegenerative pathology caused by the death of dopamine-producing neuronal cells. There are ongoing investigations into novel treatments and therapeutic targets for PD. The pathophysiology involves the formation of alpha-synuclein folds and Lewy bodies, which reduce dopamine levels. Current pharmacological treatments aim to reduce the accumulation of alpha-synuclein. The disease remains of unknown origin and has a significant social impact, but there are various treatments available and under investigation for symptom reduction and improving quality of life. A combination of pharmacological and non-pharmacological strategies is necessary for optimal outcomes.

Summary: Currently, there are no pharmacological treatments that can completely stop or reverse the progression of Parkinson's Disease (PD). Therefore, there is a need for neuroprotective therapies. This systematic review examines the effectiveness of anti-a-synuclein (a-syn) therapies in preventing PD progression in preclinical models and human clinical trials. The review found that novel preclinical anti-a-syn therapeutics reduced a-syn aggregations and protected against dopaminergic neuronal loss. Completed clinical trials showed significant tolerability and efficacy in reducing a-syn and minimal adverse effects. Overall, this review highlights the potential of anti-a-syn therapies in both preclinical and clinical settings to reduce a-syn accumulation and potentially slow down PD progression.

Summary: Parkinson's Disease (PD) is a neurodegenerative disorder characterized by Lewy bodies (LB) and degeneration of dopaminergic neurons. Alpha-synuclein (alpha SYN) is the main component of LB. Galectin-3 (GAL3) has been found to be associated with LB in PD, and our study suggests that GAL3 plays a prominent role in the aggregation process of alpha SYN and LB formation.

Summary: This study is the first attempt to investigate the direct effects of insulin signaling on pathological alpha-synuclein accumulation in dopamine neurons. The results suggest that modifying insulin signaling does not significantly affect alpha-synuclein aggregation, but the choice of culturing media can significantly affect preformed fibril-induced alpha-synuclein phosphorylation in dopamine neurons.

Summary: This study explores the diagnostic value of plasma Lewy body-associated proteins for Parkinson's disease (PD) and the discrimination of PD from healthy controls. The results suggest that a combination of p-Asyn, total alpha-syn, and oligomeric alpha-syn has a better diagnostic accuracy than individual markers. Plasma Lewy body-associated proteins may serve as non-invasive biomarkers for PD diagnosis and are not associated with the progression of symptoms.

Summary: Disease modeling in non-human subjects is crucial for clinical research. Animal models are necessary to replicate the disease process and understand the etiology and pathophysiology. Parkinson's disease, with its progressive nature and various disabilities, has specific pathological hallmarks that involve misfolded protein accumulation and degeneration of neurons. Extensive research has been conducted on Parkinson's disease animal models, including pharmacological and genetic manipulation induction. This review summarizes and discusses commonly used Parkinson's disease animal model systems, as well as their applications and limitations.

Summary: The aggregation of alpha-synuclein into inclusion bodies, known as Lewy pathology, is a key feature of Parkinson's disease and Dementia with Lewy bodies. Post mortem studies have shown that Lewy pathology follows two main distribution patterns in the brain, with some patients having pathogenic alpha-synuclein originating in the enteric nervous system and others originating inside the central nervous system.

Summary: The presence of magnetic nanoparticles in the human brain can be attributed to both endogenous and exogenous sources. Elderly brains contain non-physiological metals, likely due to the incursion of environmentally-sourced particles across the blood-brain barrier. Further investigation into the impact of exogenous magnetite/maghemite exposure on younger cohorts before the loss of blood-brain barrier integrity is essential.

Summary: Elevated levels of NfL and t-tau in CSF may serve as biomarkers to predict rapid disease progression rate in ALS. The negative correlation between CSF NfL and TDP-43 suggests that elevated levels of CSF TDP-43 in ALS is not simply due to its release during neurodegeneration. The negative relationship between plasma TDP-43 and split hand index may indicate a pathophysiological link between plasma TDP-43 and ALS.

Summary: This study used resting-state functional magnetic resonance imaging to explore the relationship between individual's spontaneous neural activity and social interaction anxiety in a nonclinical population. The results showed that social interaction anxiety was correlated with the fractional amplitude of low-frequency fluctuations in several brain regions, and that emotional intelligence partially mediated this relationship. This study provides evidence for the neural basis of social interaction anxiety in the normal population and highlights the role of emotional intelligence in this anxiety.

Summary: This study provides morphometric data on the development of the human medullary arcuate nucleus (AN) by examining the brains of preterm and perinatal infants. The results show that AN morphology demonstrates asymmetry and individual variability during the fetal period. The volume and neuronal number of AN increase exponentially with age, while neuronal density decreases exponentially. The AN may undergo neuron death and neuroblasts production after mid-gestation.

Summary: This study investigated the effects of alamandine on allodynia in a rat model and found the presence of MrgD receptors in the vlPAG and RVM regions. Microinjection of alamandine resulted in a significant increase in paw withdrawal threshold and could be blocked by an MrgD receptor antagonist. Upregulation of MrgD receptor expression following allodynia induction suggests a potential compensatory mechanism in response to pain.

Summary: The present study aimed to investigate the separate and combined effects of anodal transcranial direct current stimulation (tDCS) over the primary motor cortex (M1) and left dorsolateral prefrontal cortex (F3) regions on pain relief in patients with type-2 diabetes suffering from neuropathic pain (NP). The results showed that tDCS had the potential to induce pain relief in patients with type-2 diabetes suffering from NP. The mean perceived pain intensity in the posttest was lower in the M1 stimulation group than in the F3 stimulation group. However, more trials with larger sample sizes are necessary to define clinically relevant effects.

Summary: This study found a general impairment in humor comprehension in individuals with schizophrenia, with mental jokes being more difficult for both patients and controls. Humor comprehension was closely associated with the patients' overall pragmatic and linguistic profile, while the association with Theory of Mind (ToM) was minimal. Another notable finding was the increased appreciation of humor in individuals with schizophrenia, who rated jokes as funnier than controls did, regardless of whether they were correctly or incorrectly completed. The funniness ratings were not predicted by any measure, suggesting a dimension of humor untied to cognition or psychopathology.
