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.

Publication date: Available online 18 April 2019Source: Journal of Sport and Health ScienceAuthor(s): Xin Luan, Xiangyang Tian, Haixin Zhang, Rui Huang, Na Li, Peijie Chen, Ru WangAbstractA growing understanding of the benefits of exercise over the past few decades has prompted researchers to take an interest in the possibilities of exercise therapy. Because each sport has its own set of characteristics and physiological complications that tend to appear during exercise training, the effects and underlying mechanisms of exercise remain unclear. Thus, the first step in probing exercise effects on different diseases is the s...

Conclusions In this review, we analyzed mechanisms through which mitobolites, a distinct set of mitochondria-generated metabolites, can be released from mitochondria and then act as second messengers that contribute to cellular and organismal aging by regulating longevity-defining processes outside of mitochondria. Our analysis indicates that in eukaryotes across phyla, these second messengers of cellular aging exhibit the following common features: (1) they are produced in mitochondria in response to certain changes in the nutrient, stress, proliferation or age status of the cell; it remains unknown, however, what kind o...

Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroinfla...

We describe one such approach, albumin binding, and explain how it was applied in the development of the human GLP-1 analog liraglutide once daily and, subsequently, semaglutide once weekly. The pharmacology of these two long-acting GLP-1 analogs, in terms of improving glycemic control, reducing body weight and decreasing cardiovascular (CV) risk, is also reviewed, together with some novel biology. In addition, we describe the importance of accurate target (GLP-1 receptor) tissue expression analysis. Now an established class of agents, GLP-1-based therapies represent a significant advance in the treatment of T2D. All curr...

In this study, we explore shared epigenetic mechanisms of the association between mtDNA content and insulin levels, supporting the developmental origins of this link. First, the association between cord blood insulin and mtDNA content in 882 newborns of the ENVIRONAGE birth cohort was assessed. Cord blood mtDNA content was established via qPCR, while cord blood levels of insulin were determined using electrochemiluminescence immunoassays. Then the cord blood DNA methylome and transcriptome were determined in 179 newborns, using the human 450K methylation Illumina and Agilent Whole Human Genome 8 × 60 K microarrays, r...

We report a man (current age: 59  years) without any underlying disease presenting with right‐hand tremor at the age of 39 years, followed by slow movement, rigidity, and postural instability. He developed motor fluctuation and levodopa‐induced dyskinesia 8 years later. At the age of 58 years, cognitive decline and visual h allucination ensued; he was institutionalized thereafter. We used multiplex ligation‐dependent probe amplification, which demonstrated no large deletions or duplications of relevant PD genes. Next, targeted sequencing panel covering 51 genes causative for PD was applied for the...

P, Sabate R Abstract Amyloid aggregation is linked to an increasing number of human disorders from non-neurological pathologies such as type-2 diabetes to neurodegenerative ones such as Alzheimer or Parkinson's diseases. Thirty-six human proteins have shown the capacity to aggregate into pathological amyloid structures. To date, it is widely accepted that amyloid folding/aggregation is a universal process present in eukaryotic and prokaryotic cells. In the last decade, several studies have unequivocally demonstrated that bacterial inclusion bodies - insoluble protein aggregates usually formed during heterologous p...

This study provides a possible reason why genes carrying health risks have persisted in human populations. The second found evidence for multiple variants in genes related to ageing that exhibited antagonistic pleiotropic effects. They found higher risk allele frequencies with large effect sizes for late-onset diseases (relative to early-onset diseases) and an excess of variants with antagonistic effects expressed through early and late life diseases. There also exists other recent tangible evidence of antagonistic pleiotropy in specific human genes. The SPATA31 gene has been found under strong positive genomic sele...
