Cellular and Molecular Events Leading to Paraquat-Induced Apoptosis: Mechanistic Insights into Parkinson’s Disease Pathophysiology

A-Synuclein, Parkinson's Disease, Pesticides /

Parkinson’s disease (PD) is a progressive neurodegenerative disorder characterized by the cardinal features of tremor, bradykinesia, rigidity, and postural instability, in addition to other non-motor symptoms. Pathologically, PD is attributed to the loss of dopaminergic neurons in the substantia nigra pars compacta, with the hallmark of the presence of intracellular protein aggregates of α-synuclein in […]

Bacteria-Derived Protein Aggregates Contribute to the Disruption of Host Proteostasis

A-Synuclein, Butyrate, Parkinson's Disease, Short Chain Fatty Acids /

Neurodegenerative protein conformational diseases are characterized by misfolding and aggregation of metastable proteins encoded within the host genome. The host is also home to thousands of proteins encoded within exogenous genomes harbored by bacteria, fungi, and viruses. Yet, their contributions to host protein-folding homeostasis, or proteostasis, remain elusive. Recent studies, including our previous work, suggest

Butyrate Inhibits Osteoclast Activity In Vitro and Regulates Systemic Inflammation and Bone Healing in a Murine Osteotomy Model Compared to Antibiotic-Treated Mice

Butyrate, Gut Microbiota, Parkinson's Disease, Short Chain Fatty Acids /

Short-chain fatty acids (SCFAs) produced by the gut microbiota have previously been demonstrated to play a role in numerous chronic inflammatory diseases and to be key mediators in the gut-bone signaling axis. However, the role of SCFAs in bone fracture healing and its impact on systemic inflammation during the regeneration process has not been extensively

Periodontal inflammatory disease is associated with the risk of Parkinson’s disease: a population-based retrospective matched-cohort study

endondonics, Oral Microbiome, Parkinson's Disease /

Individuals exposed to PID were 1.431 times more likely to develop PD than those who were not exposed. However, future long-term, larger or national data sets combined with genes, environmental exposure, lifestyle changes, dietary habits, and accurately defined PD diagnosis should be investigated to support the current research results.

Direct evidence of Parkinson pathology spread from the gastrointestinal tract to the brain in rats

A-Synuclein, Gut Permeability / Leaky Gut, Gut-Brain axis, Parkinson's Disease /

The cellular hallmarks of Parkinson’s disease (PD) are the loss of nigral dopaminergic neurons and the formation of α-synuclein-enriched Lewy bodies and Lewy neurites in the remaining neurons. Based on the topographic distribution of Lewy bodies established after autopsy of brains from PD patients, Braak and coworkers hypothesized that Lewy pathology primes in the enteric

Relationships of Nutritional Factors and Agrochemical Exposure with Parkinson’s Disease in the Province of Brescia, Italy

A-Synuclein, Diet and Exercise, Gut Dysbiosis, Parkinson's Disease /

Environmental exposures to agrochemicals and nutritional factors may be associated with Parkinson’s Disease (PD). None of the studies to date has examined the combined effects of diet and agricultural chemical exposure together. To address these research gaps, we aimed to assess the association of nutritional factors and agrochemical exposure with the risk of PD. A

Brain-Gut-Microbiota Axis in Schizophrenia and Parkinson’s
Disease

Gut Dysbiosis, Gut-Brain axis, Parkinson's Disease, Pre-PD, Vagal Nerve /

Dopaminergic cells, which use dopamine as a neurotransmitter, arenot as numerous as other brain nerve cells such as serotonergic andGABAergic neurons. However, dopamine neurons project to a varietyof important brain regions to control movement, emotion, the rewardsystem, and the secretion of prolactin. Both schizophrenia andParkinson’s disease are disorders of the dopaminergic neurotransmissions, but schizophrenia has

The role of the probiotic Akkermansia muciniphila in brain functions: insights underpinning therapeutic potential

Gut Dysbiosis, Gut Microbiota, Gut-Brain axis, Parkinson's Disease, Probiotics, Prebiotics and Symbiotics /

The role of Akkermansia muciniphila, one of the most abundant microorganisms of the intestinalmicrobiota, has been studied extensively in metabolic diseases, such as obesity and diabetes. Itis considered a next-generation probiotic microorganism. Although its mechanism of action hasnot been fully elucidated, accumulating evidence indicates the important role of A. muciniphilain brain functions via the gut-brain

The increased worldwide prevalence of pre-diabetes and diabetes, especially type 2 diabetes, requiring different strategies for their prevention and management. A new focus is the reversal of diabetes dysbiosis, a disruption of gut microbiota homeostasis, which is closely related to elevated blood glucose levels and altered metabolic parameters. In this sense, a balanced diet plays a key role, and,

Inflammation and immune dysfunction in Parkinson disease

Gut Microbiota, Parkinson's Disease, Pre-PD /

Parkinson disease (PD) is a progressive neurodegenerative disease that affects peripheral organs as well as the central nervous system and involves a fundamental role of neuroinflammation in its pathophysiology. Neurohistological and neuroimaging studies support the presence of ongoing and end-stage neuroinflammatory processes in PD. Moreover, numerous studies of peripheral blood and cerebrospinal fluid from patients
