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 […]

Plasma Metabolite Signature Classifies Male LRRK2 Parkinson’s Disease Patients

Autophagy, Biomarkers, Parkinson's Disease, Pre-PD /

Parkinson’s disease (PD) is a progressive neurodegenerative disease, causing loss of motor and nonmotor function. Diagnosis is based on clinical symptoms that do not develop until late in the disease progression, at which point the majority of the patients’ dopaminergic neurons are already destroyed. While many PD cases are idiopathic, hereditable genetic risks have been

Is Fasting Good For Your Brain? The Effects of Fasting on the Brain

Autophagy, Fasting, Parkinson's Disease, Pre-PD /

Fasting promotes autophagy, a vital recycling process, and stimulates the growth factor BDNF. Autophagy is impaired in neurodegenerative conditions such as Alzheimer’s and Parkinson’s. BDNF is crucial for brain health, and low levels are associated with depression. Hence, fasting improves brain health by multiple mechanisms. While fasting has been performed in one form or another

Autophagy-Lysosomal Pathway as Potential Therapeutic Target in Parkinson’s Disease

Autophagy, Parkinson's Disease, Pre-PD /

Cellular quality control systems have gained much attention in recent decades. Amongthese, autophagy is a natural self-preservation mechanism that continuously eliminates toxic cellularcomponents and acts as an anti-ageing process. It is vital for cell survival and to preserve homeostasis.Several cell-type-dependent canonical or non-canonical autophagy pathways have been reportedshowing varying degrees of selectivity with regard to

Sodium butyrate attenuates rotenone-induced toxicity by activation of autophagy through epigenetically regulating PGC-1α expression in PC12 cells

Autophagy, Butyrate, Parkinson's Disease, Short Chain Fatty Acids /

Short-chain fatty acids (SCFAs) are considered the key molecular link between gut microbiota and pathogenesis of Parkinson’s disease (PD). However, the role of SCFAs in PD pathogenesis is controversial. Autophagy is important for the degradation of α-synuclein, which is critical to the development of PD. However, whether SCFAs can regulate autophagy in PD remains unknown.

Brain-derived Neurotrophic Factor and Its Applications through Nanosystem Delivery

Autophagy, Parkinson's Disease /

Brain-derived neurotrophic factor (BDNF) is a protein that performs a neurotrophic function.BDNF and its receptors are widely expressed in the nervous system and can promote the growthof neurons and the formation of neuronal synapses in the brain. Studies have shown that a lack ofBDNF can lead to impairment of memory and cognitive functions, indicating that

Gut dysbiosis, defective autophagy and altered immune responses in neurodegenerative diseases: Tales of a vicious cycle

Autophagy, Gut Dysbiosis, Parkinson's Disease, Probiotics, Prebiotics and Symbiotics /

The human microbiota comprises trillions of symbiotic microorganisms and is involved in regulating gastrointestinal (GI), immune, nervous system and metabolic homeostasis. Recent observations suggest a bidirectional communication between the gut microbiota and the brain via immune, circulatory and neural pathways, termed the Gut-Brain Axis (GBA). Alterations in gut microbiota composition, such as seen with an increased number of pathobionts

Does Data-Independent Acquisition Data Contain Hidden Gems? A Case Study Related to Alzheimer’s Disease

Autophagy, Parkinson's Disease /

One of the potential benefits of using data-independent acquisition (DIA) proteomics protocols is that information not originally targeted by the study may be present and discovered by subsequent analysis. Herein, we reanalyzed DIA data originally recorded for global proteomic analysis to look for isomerized peptides, which occur as a result of spontaneous chemical modifications to

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
