Parkinson's Disease: New Biomarker Effort

From the NIH: NIH launches collaborative effort to find biomarkers for Parkinson'sNew online resource will support data sharingNIH News15 January 2013 [snip] "A new initiative aims to accelerate the search for biomarkers — changes in the body that can be used to predict, diagnose or monitor a disease — in Parkinson's disease, in part by improving collaboration among researchers and helping patients get involved in clinical studies. "A lack of biomarkers for Parkinson's has been a major challenge for developing better treatments. The Parkinson’s Disease Biomarkers Program (PDBP) supports efforts to invent new technologies and analysis tools for biomarker discovery, to identify and validate biomarkers in patients, and to share biomarker data and resources across the Parkinson's community. The program is being launched by the National Institute of Neurological Disorders and Stroke (NINDS), part of the National Institutes of Health." [snip] Read the full press release

Abstract BACKGROUND: Leukoaraiosis (LA), widely accepted as a feature of cerebral small vessel disease, significantly increases the incidence of stroke, dementia, and death. Cerebral small artery disease has been considered as one of the main causes of LA. However, since the term "venous collagenosis" (VC) was proposed in an atrophy research in 1995, there have been pathological and neuroimaging studies proving the association between the venous system and LA in aging, Alz-heimer's disease (AD), and Parkinson's disease. SUMMARY: Autopsy studies confirmed that thickening of the lumen wall in venules,...

AbstractAdenosine is a ubiquitous neuromodulator that plays a role in sleep, vasodilation, and immune response and manipulating the adenosine system could be therapeutic for Parkinson ’s disease or ischemic stroke. Spontaneous transient adenosine release provides rapid neuromodulation; however, little is known about the effect of sex as a biological variable on adenosine signaling and this is vital information for designing therapeutics. Here, we investigate sex differences in spontaneous, transient adenosine release using fastā€scan cyclic voltammetry to measure adenosinein vivo in the hippocampus CA1, basolateral ...

AbstractGlucagon-like peptide-1 (GLP-1) is a gut-derived peptide that has various physiological actions. One of its main actions is the regulation of blood glucose level when it is elevated as it potentiates insulin release. It is also known that GLP-1 protects neurons from damage caused by neurodegenerative diseases. Lixisenatide is one of the GLP-1 analogues that has a strong affinity to the GLP-1 receptor. Experimental animal studies have shown that it holds a neuroprotective effect in Parkinson, myocardial, and cerebral ischemic disease animal models. The beneficial effect of lixisenatide on the brain after cerebral is...

ConclusionsVisceral fat accumulation was associated with MCI, especially non-amnestic MCI, in community-dwelling older Japanese women. These results suggest that visceral fat accumulation is partially protective against cognitive impairment.

The spinal cord stimulation (SCS) market growth should improve in 2020 as leaders in the space launch new products and benefit from recent acquisitions and invest in potential indication expansions, according to Needham &Co.'s Mike Matson. The medtech analyst published a report Monday sharing his takeaways from the North American Neuromodulation Society (NANS) meeting in Las Vegas, NV over the weekend. Matson noted that SCS device market growth should continue to improve in 2020 and beyond, thanks to a number of factors. The analyst estimates that SCS currently represents about $2.5 billion, whi...

Conclusions: Tai Chi may be beneficial for improving balance and reducing falls in older people and those with Parkinson disease. Because of limitations and inconsistent conclusions, further rigorous, normative and comprehensive SRs are needed to provide robust evidence for definitive conclusions.

Abstract 17β-Estradiol (estradiol or E2) is a steroid hormone that has been broadly applied as a neuroprotective therapeutic for a variety of neurodegenerative and cerebrovascular disorders such as ischemic stroke, Alzheimer's disease, and Parkinson's disease. Several laboratory and clinical studies have reported that estrogen replacement therapy (ERT) had no effect against these diseases in elderly postmenopausal women, and at worst, increased their risk of onset and mortality. This review focuses on the growing body of data from in vitro and animal models characterizing the potential underlying mechanisms a...

Conclusion:Our findings demonstrate that rTMS treatment and hMSC transplantation could synergistically create a favorable microenvironment for cell survival within the PD rat brain, through alteration of soluble factors such as neurotrophic/growth factors and anti-/pro-inflammatory cytokines related to neuronal protection or repair, with preservation of DA neurons and improvement of motor functions.

Abstract With the increasing prevalence of Parkinson's disease, there is an immediate need to interdict disease signs and symptoms. In recent years this need was met through therapeutic approaches focused on regenerative stem cell replacement and alpha-synuclein clearance. However, neither have shown long-term clinical benefit. A novel therapeutic approach designed to affect disease is focused on transforming the brain's immune microenvironment. As disordered innate and adaptive immune functions are primary components of neurodegenerative disease pathogenesis, this has emerged as a clear opportunity for therapeuti...
