Linking circadian rhythms to microbiome-gut-brain axis in aging-associated neurodegenerative diseases

ENS, Gut Dysbiosis, Gut Microbiota /

Emerging evidence suggests that both disruption of circadian rhythms and gut dysbiosis are closely related to aging-associated neurodegenerative diseases. Over the last decade, the microbiota-gut-brain axis has been an emerging field and revolutionized studies in pathology, diagnosis, and treatment of neurological disorders. Crosstalk between the brain and gut microbiota can be accomplished via the endocrine, […]

Chaperone-Mediated Autophagy in Neurodegenerative
Diseases and Acute Neurological Insults in the Central
Nervous System

Autophagy, Parkinson's Disease, Pre-PD /

Autophagy is an important function that mediates the degradation of intracellular proteinsand organelles. Chaperone-mediated autophagy (CMA) degrades selected proteins and has a crucialrole in cellular proteostasis under various physiological and pathological conditions. CMA dysfunction leads to the accumulation of toxic protein aggregates in the central nervous system (CNS) andis involved in the pathogenic process of

Modifying the diet and gut microbiota to prevent and manage neurodegenerative diseases

Diet and Exercise, Gut Dysbiosis, Gut Microbiota, Gut-Brain axis, Parkinson's Disease /

The global prevalence of Alzheimer’s disease and Parkinson’s disease is steadily increasing due to the aging population. The lack of effective drugs against these neurodegenerative disorders makes it imperative to identify new strategies for their prevention and treatment. Recent studies have revealed that harnessing the power of the gut microbiota through modification of diet may

Alpha-synuclein as a Potential Biomarker for Parkinson’s Disease and Other
Synucleinopathies: Gaps, Challenges, and Opportunities

A-Synuclein, Biomarkers /

Parkinson’s disease (PD), the second most common progressive neurodegenerative disease,develops and progresses for 10-15 years before the clinical diagnostic symptoms of thedisease are manifested. Furthermore, several aspects of PD pathology overlap with otherneurodegenerative diseases (NDDs) linked to alpha-synuclein aggregation, also calledsynucleinopathies. Therefore, there is an urgent need to discover and validate earlydiagnostic and prognostic markersthat

Gut Microbiota Dysbiosis: Triggers, Consequences, Diagnostic and Therapeutic Options

Butyrate, Fecal Transplants (FMT), Gut Dysbiosis, Gut Microbiota, Probiotics, Prebiotics and Symbiotics, Short Chain Fatty Acids /

The global incidence of numerous immune-mediated, metabolic, neurodegenerative, and psychiatric diseases is steadily increasing [1,2,3]. The increased morbidity of human populations makes them more vulnerable to additional burdens, including infectious diseases. For example, the mortality rate of diabetics infected with the original variant of the SARS Co-2 virus was about twice that of the general

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

Deciphering the prion-like behavior of pathogenic protein aggregates in neurodegenerative diseases

A-Synuclein, Autonmic nervous system, Biomarkers, Gut-Brain axis /

Neurodegenerative diseases are hitherto classified based on their core clinical features, the anatomical distribution of neurodegeneration, and the cell populations mainly affected. On the other hand, the wealth of neuropathological, genetic, molecular and biochemical studies have identified the existence of distinct insoluble protein aggregates in the affected brain regions. These findings have spread the use of a

Gut Microbiota-Brain Interaction with Special Reference to Alzheimer’s Disease

Butyrate, Gut Dysbiosis, Gut Microbiota, Gut-Brain axis, Parkinson's Disease, Pre-PD /

Gut microbiota is showing and raising evidence that the dynamic changes in the gut microorganism can influence physiology and behavior of brain. Dysbiosis or dysbacteriosis is a condition of microbial imbalance inside the intestinal microbiome. It has been associated with disorders of intestinal and extra‐intestinal such as inflammatory bowel disease and other multiple diseases like

The link between the gut microbiota and Parkinson’s Disease: A systematic mechanism review with focus on α-synuclein transport

A-Synuclein, ENS, Gut Dysbiosis, Gut Microbiota, Parkinson's Disease, Pre-PD /

Research has suggested a link between the gut microbiota and Parkinson’s Disease (PD), and an early involvement of gastrointestinal dysfunction has been reported in patients. A mechanism review was performed to investigate whether the neurodegenerative cascade begins in the gut; mediated by gut dysbiosis and retrograde transport of α-synuclein. This review provides a summary of

Neuronal Autophagy: Characteristic Features and Roles in Neuronal Pathophysiology

Autophagy, Parkinson's Disease /

Autophagy is an important degradative pathway that eliminates misfolded proteins and damaged organelles from cells. Autophagy is crucial for neuronal homeostasis and function. A lack of or deficiency in autophagy leads to the accumulation of protein aggregates, which are associated with several neurodegenerative diseases. Compared with non-neuronal cells, neurons exhibit rapid autophagic flux because damaged
