Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder, with an unknown etiology and no specific treatment. Emerging single-cell and single-nucleus RNA sequencing (sc/snRNA-seq) technologies have become instrumental in unravelling cellular heterogeneity and characterizing molecular signatures at single-cell resolution. Single-cell T cell receptor sequencing (scTCR-seq) and single-cell B cell receptor sequencing (scBCR-seq) technologies provide unprecedented opportunities to explore the immune repertoire diversity.

Article Synopsis
  • Parkinson's disease (PD) is characterized by the degeneration of dopamine-producing neurons in the brain, specifically in the substantia nigra, but the underlying causes are still not fully understood.
  • Human midbrain organoids (hMLOs) are being developed as a new model to better investigate PD, test drugs, and explore potential therapies.
  • This review covers how hMLOs are created, their usefulness in PD studies, and the difficulties faced in improving these organoids, suggesting ways to optimize their construction.

Background: Phase-amplitude coupling (PAC) between the phase of low-frequency signals and the amplitude of high-frequency activities plays many physiological roles and is involved in the pathological processed of various neurological disorders. However, how low-frequency and high-frequency neural oscillations or information synchronization activities change under chronic central hypoxia in OSA patients and whether these changes are closely associated with OSA remains largely unexplored. This study arm to elucidate the long-term consequences of OSA-related oxygen deprivation on central nervous system function.

Alzheimer's disease (AD) is the most common cause of dementia, characterized by memory loss, cognitive decline, personality changes, and various neurological symptoms. The role of blood-brain barrier (BBB) injury, extracellular matrix (ECM) abnormalities, and oligodendrocytes (ODCs) dysfunction in AD has gained increasing attention, yet the detailed pathogenesis remains elusive. This study integrates single-cell sequencing of AD patients' cerebrovascular system with a genome-wide association analysis.

  • A study analyzed data from over 500,000 participants in the UK Biobank to explore risk factors associated with Parkinson's Disease (PD) using a phenome-wide association study (PheWAS) and polygenic risk scores (PRSS).
  • The researchers identified 267 risk factors related to PD, with 27 factors showing strong causal relationships, including fluid intelligence and certain dietary habits.
  • Interestingly, some behaviors like playing computer games and a lower salt intake were found to potentially protect against PD, highlighting the importance of both genetic and lifestyle factors in understanding the disease.

Parkinson's disease (PD) is a multifactorial neurodegenerative disorder with high prevalence among the elderly, primarily manifested by progressive decline in motor function. The aging global demographic and increased life expectancy have led to a rapid surge in PD cases, imposing a significant societal burden. PD along with other neurodegenerative diseases has garnered increasing attention from the scientific community.

Introduction: Alzheimer's disease (AD) is the most widespread neurodegenerative disease in the world. Previous studies have shown that peripheral immune dysregulation plays a paramount role in AD, but whether there is a protective causal relationship between peripheral immunophenotypes and AD risk remains ambiguous.

Methods: Two-sample Mendelian randomization (MR) was performed using large genome-wide association study (GWAS) genetic data to assess causal effects between peripheral immunophenotypes and AD risk.

Article Synopsis
  • The study examines the links between air pollution, greenspace exposure, and the risk of developing Parkinson's Disease (PD) using data from 441,462 participants in the UK Biobank over a median follow-up of 12.23 years.
  • Results indicate that increased levels of nitrogen dioxide (NO) and particulate matter (PM) were linked to a higher risk of PD, while other pollutants did not show the same association.
  • Furthermore, exposure to greenspace seemed to offer protective effects against PD by lowering NO and PM levels, suggesting that enhancing greenspace might help mitigate PD risk.

Among the various manifestations of COVID-19, the neurological implications of SARS-CoV-2 infection are of significant concern. Marchiafava-Bignami disease (MBD), a neurodegenerative disorder, exhibits a clinical spectrum ranging from mild progressive dementia in its chronic form to states of acute coma and varied mortality rates. Acute MBD primarily occurs in chronic alcoholics and malnourished individuals and is characterized by sudden loss of consciousness, seizures, confusion, and psychosis.

  • The study explored the link between irritable bowel syndrome (IBS) and Parkinson's disease (PD) using a large cohort from the UK Biobank, analyzing data from 426,911 participants.
  • Initial findings suggested that IBS patients had a decreased risk of developing PD; however, this association weakened when accounting for other demographic factors like age and gender.
  • Ultimately, the research concluded that IBS does not significantly influence the risk of developing PD, offering important insights for managing patients with IBS.

Background: The peripheral immune system is altered in Parkinson's disease (PD), but the causal relationship between the two remains controversial. In this study, we aimed to estimate the causal relationship between peripheral immune features and PD using a two-sample Mendelian randomization (MR) approach.

Methods: Genome-wide association study (GWAS) data of peripheral blood immune signatures from European populations were used for exposure and PD summary statistics were used as results.

Introduction: Inflammatory Bowel Disease (IBD) and Parkinson's disease (PD) are both chronic, progressive disorders. As such, given the inconclusive results of extensive research on the association between IBD and PD, our study intends to examine this relationship further using the UK Biobank database.

Methods: We conducted a prospective cohort study using the Cox proportional hazards model, analyzing data from the UK Biobank to investigate the relationship between IBD and PD, following subjects until PD diagnosis, loss to follow up, death or study termination on 30 June, 2023.

Genome-wide association studies (GWAS) have identified multiple risk variants for Parkinson's disease (PD). Nevertheless, how the risk variants confer the risk of PD remains largely unknown. We conducted a proteome-wide association study (PWAS) and summary-data-based mendelian randomization (SMR) analysis by integrating PD GWAS with proteome and protein quantitative trait loci (pQTL) data from human brain, plasma and CSF.

There is yet no scientific consensus, and for now, on how to choose the optimal interpolation method and its parameters for mapping soil-borne organic pollutants. Take the polychlorinated biphenyls (PCBs) for instance, we present the comparison of some classic interpolation methods using a high-resolution soil monitoring database. The results showed that empirical Bayesian kriging (EBK) has the highest accuracy for predicting the total PCB concentration, while root mean squared error (RMSE) in inverse distance weighting (IDW) is among the highest in these interpolation methods.

Background: While previous genome-wide association studies (GWAS) have identified multiple risk variants for migraine, there is a lack of evidence about how these variants contribute to the development of migraine. We employed an integrative pipeline to efficiently transform genetic associations to identify causal genes for migraine.

Methods: We conducted a proteome-wide association study (PWAS) by combining data from the migraine GWAS data with proteomic data from the human brain and plasma to identify proteins that may play a role in the risk of developing migraine.
