Supply bottleneck impairs nerve function

(University of W ü rzburg) Impaired transport processes in neurons contribute to diseases such as amyotrophic lateral sclerosis (AML). W ü rzburg scientists have now identified key actors in these processes.

elo G Abstract Apathy is recognized as the most common behavioral change in several neurodegenerative diseases, including amyotrophic lateral sclerosis (ALS), a multisystem neurodegenerative disorder. Particularly, apathy has been reported to be associated with poor ALS prognosis. However, the brain microstructural correlates of this behavioral symptom, reported as the most common in ALS, have not been completely elucidated. Using diffusion tensor imaging (DTI) and tract-based spatial statistics (TBSS), here we aimed to quantify the correlation between brain microstructural damage and apathy scores in the early st...

Amyotrophic lateral sclerosis (ALS) is a fatal motor neuron disease that occurs in 4 among 100 000 people in the United States. Individuals with ALS gradually lose their ability to control voluntary muscles, diminishing their ability to communicate. A comprehensive multidatabase search retrieved 31 qualitative research articles that addressed persons with end-of-life experiences with ALS. Inclusion/exclusion criteria were applied and a critical appraisal was applied for the final 8 included articles. First-person data extraction from the final articles represented emergence of 3 themes significant to persons with ALS: deci...

Conclusions: Despite some statistical instability of the results due to limitations in sample size, our study supports the role of CSF pNfH as a prognostic biomarker for motor neuron diseases presenting with UMN signs. A potential power to discriminate between ALS and other UMN syndromes at presentation, and between all of the examined MND and HC, has been detected for both CSF and serum pNfH.Neurodegener Dis 2018;18:255 –261

AbstractIntroductionThe progression of amyotrophic lateral sclerosis (ALS) leads to a decline of the nutritional status that represents an independent prognostic factor for survival. Recent studies recognize the muscle tissue as an endocrine organ able to release several molecules, called myokines. Among them, irisin seems to be involved in the regulation of metabolism, body weight and development and function of the nervous system.Objectives(1) To evaluate irisin serum levels in patients with ALS, with comparison to healthy subjects; (2) to assess the possible association of circulating irisin levels of ALS patients with ...

In this study we used hSOD1(G93A) microglial cells to investigate the effects of the antioxidant and anti-inflammatory cyclic dipeptide (His-Pro) on LPS-induced inflammasome activation. We found that cyclo(His-Pro) inhibits NLRP3 inflammasome activation by reducing protein nitration via reduction in NO and ROS levels, indicative of lower peroxynitrite generation by LPS. Low levels in peroxynitrite are related to NF-κB inhibition responsible for iNOS down-regulation and NO dampening. On the other hand, cyclo(His-Pro)-mediated ROS attenuation, not linked to Nrf2 activation in this cellular model, is ascribed to increas...

(University of Missouri-Columbia) There is no cure for amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's Disease, but new findings from the University of Missouri School of Medicine and the University of Missouri College of Veterinary Medicine are deepening researchers' understanding of a common ALS symptom: swallowing problems.
