Emory University researchers, investigating the role of dopamine in the regulation of vocal learning through auditory feedback, observed that reducing this neurotransmitter in a specific brain area, the basal ganglia, considerably impairs learning. The study, in songbirds called Bengalese finches, further illuminate the role of dopamine in vocal behavior, and is relevant to Parkinson’s disease,…

For the first time, researchers have identified the point at which alpha-synuclein – the protein whose aggregation leads to Parkinson’s disease – becomes toxic. The findings, published in the journal PNAS, shed new light on the toxicity processes leading to disease development and might provide clues in the…

Researchers have discovered the molecular mechanisms behind calorie restriction’s neuroprotective effect in Parkinson’s disease, and propose a new therapeutic approach that uses existing drugs to reproduce the effects demonstrated in an animal model of the disease. The study by Monash University Biomedicine Discovery Institute scientists, “Ghrelin-AMPK Signaling Mediates the Neuroprotective…

In an editorial published in the Journal of Alzheimer’s Disease, scientists and clinicians working in Alzheimer’s disease (AD) voiced concern over largely ignored research indicating that certain microbes — namely, the herpes simplex virus type 1 (HSV1), Chlamydia pneumoniae, and several types of spirochaete — might be involved in Alzheimer’s pathogenesis. The…

International Stem Cell Corporation is now enrolling patients in a Phase 1 clinical trial of its lead product candidate, ISC-hpNSC — human parthenogenetic stem cell-derived neural stem cells — for patients with moderate to severe Parkinson’s disease. Parthenogenesis uses unfertilized eggs to create pluripotent human stem cells and hopes to significantly advance the field of…
