Type 2 diabetics face a 32% higher risk of developing Parkinson's in old age

Professor Tom Warner, from the Neurology Institute at University College London, who led the study, said it was most comprehensive evidence to date to show a link.

LemkulAbstractPathological aggregation of amyloid-forming proteins is a hallmark of a number of human diseases, including Alzheimer's, type 2 diabetes, Parkinson's, and more. Despite having very different primary amino acid sequences, these amyloid proteins form similar supramolecular, fibril structures that are highly resilient to physical and chemical denaturation. To better understand the structural stability of disease-related amyloids and to gain a greater understanding of f...

AbstractPurpose of ReviewSelenium, a trace element, is ubiquitous in the environment. The main source of human exposure is diet. Despite its nutritional benefits, it is one of the most toxic naturally occurring elements. Selenium deficiency and overexposure have been associated with adverse health effects. Its level of toxicity may depend on its chemical form, as inorganic and organic species have distinct biological properties.Recent FindingsNonexperimental and experimental studies have generated insufficient evidence for a role of selenium deficiency in human disease, with the exception of Keshan disease, a cardiomyopath...

In this study, we found that TXNIP deficiency induces accelerated senescent phenotypes of mouse embryonic fibroblast (MEF) cells under high glucose condition and that the induction of cellular ROS or AKT activation is critical for cellular senescence. Our results also revealed that TXNIP inhibits AKT activity by a direct interaction, which is upregulated by high glucose and H2O2 treatment. In addition, TXNIP knockout mice exhibited an increase in glucose uptake and aging-associated phenotypes including a decrease in energy metabolism and induction of cellular senescence and aging-associated gene expression. We propose that...

In the materials noted here, a Buck Institute researcher puts forward a view of just one side of the science of advanced glycation end-products (AGEs) and their role in degenerative aging. AGEs are sugary metabolic byproducts of many different varieties, both present in the diet and generated in the body. In the view of AGEs and aging expounded here, near all of the many types of AGE are important, most are transient and levels will vary in response to day to day circumstances, dietary intake of AGEs probably has a significant negative influence on long-term health, and AGEs present in tissues disrupt metabolism by hammeri...

I have posted a few notes about predictive diagnostic algorithms (see:An Algorithm Using Medical Record Data Predicts Risk for Parkinson's Disease;Should the Work Product of"Non-Explainable" Medical Algorithms Be Ignored) and disease risk scores (see:Genetic Risk Scores: Ready for Inclusion in the Medical Record?). Using AI techniques, researchers at Massachusetts General are developing a web site that will display a risk score for five common diseases after consumers upload their DNA to the site (see:Clues to Your Health Are Hidden at 6.6 Million Spots in Your DNA). The algorithm takes into account mill...

This dynamic population of microorganisms, termed the human microbiota, resides mainly within the gastrointestinal tract. It is widely accepted that highly diverse and stable microbiota promote overall human health. Colonization of the gut with maladaptive and pathogenic microbiota, a state also known as dysbiosis, is associated wit...

Abstract Protein misfolding and aggregation into fibrillar deposits is a common feature of a large group of degenerative diseases affecting the central nervous system or peripheral organs, termed protein misfolding disorders (PMDs). Despite their established toxic nature, clinical trials aiming to reduce misfolded aggregates have been unsuccessful in treating or curing PMDs. An interesting possibility for disease intervention is the regular intake of natural food or herbal extracts, which contain active molecules that inhibit aggregation or induce the disassembly of misfolded aggregates. Among natural compounds, p...

(Bentham Science Publishers) Arranging into well-organized fibrillar aggregate, commonly known as amyloid fibril is an inherent property of any polypeptide chain. Amyloid fibrils are associated with a number of severe human pathologies like the Alzheimer's disease, Parkinson's disease, type 2 diabetes and many more. This review article includes the recent studies of identification and characterization of possible conformations of proteins which can act as aggregation precursor state (APS).

Parkinson's disease (PD) is the second most common neurodegenerative disease, and there is no recognised therapy to cure it. Recently, it has been shown that treatments to improve insulin resistance in type 2 diabetes (T2DM) may be useful for PD patients. In previous studies, the glucagon-like peptide-1 (GLP-1) receptor agonist liraglutide showed good neuroprotective effects in animal models of PD. In addition, the GLP-1 mimetic exendin-4 has shown good protective effects in PD patients in a phase II clinical trial.
