Humoral immunity response to human endogenous retroviruses K/W differentiates between amyotrophic lateral sclerosis and other neurological diseases
European Journal of Neurology, EarlyView.
Parkinson's Disease (PD) is diagnosed clinically. Reliable non-invasive PD biomarkers are actively sought. Transfer RNAs produce short non-coding RNAs, the tRNA-derived fragments (tRF). tRF have been shown to play diverse roles, including in Amyotrophic Lateral Sclerosis, and the response to ischemic stroke. Rich tRF populations are being reported in biofluids. We explored the possibility that tRF can serve as non-invasive biomarkers for PD.

However, the mechanism of ALS has not yet been elucidated, and no cure has been found. Research has revealed that a mutation of the Cu/Zn superoxide dismutase (SOD1) gene is linked to familial ALS and that pot...
Conclusion: Our results do not support the causal role of genetically increased or decreased BMI on the risk of ALS.
(Sanford Burnham Prebys Medical Discovery Institute) New research on amyotrophic lateral sclerosis (AML) has revealed that a protein called membralin plays a key role in the disease process. The study, published in Journal of Clinical Investigation, suggests that membralin-boosting gene therapy is a potential therapeutic direction to treat this often deadly disease.
ConclusionThese findings collectively suggested that initial symptoms influenced phenotypes in SCA3 and that neurodegeneration in different parts of brain may induce different disease severity in SCA3.
Conclusion: Overall, and even though we must account for the limitations of the indirect methods and models used for prevalence estimation, we probably have a very high ALS/MND prevalence in Portugal. It would be important to create registries, particularly in rare diseases, for better organization and distribution of healthcare services and resources, particularly at the level of ventilatory support.Neuroepidemiology
Amyotrophic lateral sclerosis (ALS) is a debilitating disease with few treatment options. Progress towards new therapies requires validated disease biomarkers, but there is no consensus on which fluid-based me...
Conclusion: This study provides evidence that not all ALS patients show contiguous clinical or electrophysiological spread patterns. The electrophysiological spread pattern can affect the functional staging in ALS patients. Keywords：Amyotrophic lateral sclerosis, prion-like mechanism, electrophysiology, spread pattern
Amyotrophic lateral sclerosis (ALS) is the most common motor neuron degenerative disease in adults and has also been proven to be a type of conformational disease associated with protein misfolding and dysfunction. To date, more than 150 distinct genes have been found to be associated with ALS, among which Superoxide Dismutase 1 (SOD1) is the first and the most extensively studied gene. It has been well established that SOD1 mutants-mediated toxicity is caused by a gain-of-function rather than the loss of the detoxifying activity of SOD1. Compared with the clear autosomal dominant inheritance of SOD1 mutants in ALS, the po...
