  • New study on development of parkinson’s disease is ‘on the nose’

    August 03, 2020
    Results of the study, published in the journal Brain Pathology , showed that application of an irritating component of a bacterium’s cell wall induces inflammation in the areas exactly where the olfactory neurons project, called the olfactory bulb. Moreover, these areas show the hallmark signs of PD, depositions of alpha-synuclein, the core components of Lewy bodies. PD is characterized by progressive motor and non-motor symptoms linked to alpha-synuclein pathology and the loss of dopaminergic neurons in the nigrostriatal system. Toxic aggregates of alpha-synuclein can arise from either overexpression of the protein, changes in protein modifications, and from hereditary mutations.

Just a single treatment to inhibit PTB in mice converted native astrocytes, star-shaped support cells of the brain, into neurons that produce the neurotransmitter dopamine. As a result, the mice’s Parkinson’s disease symptoms disappeared.

  • Study ties stroke-related brain blood vessel abnormality to gut bacteria

    June 03, 2020
    In a nationwide study, NIH funded researchers found that the presence of abnormal bundles of brittle blood vessels in the brain or spinal cord, called cavernous angiomas (CA), are linked to the composition of a person’s gut bacteria. Also known as cerebral cavernous malformations, these lesions which contain slow moving or stagnant blood, can often cause hemorrhagic strokes, seizures, or headaches. Current treatment involves surgical removal of lesions when it is safe to do so. Previous studies in mice and a small number of patients suggested a link between CA and gut bacteria. This study is the first to examine the role the gut microbiome may play in a larger population of CA patients.

In fact, the researchers report that signs of autoimmunity can appear in Parkinson’s disease patients years before their official diagnosis.

  • Novel Risk Gene for Parkinson's Identified

    April 15, 2020
    Screening DNA of Parkinson’s patients in the Christine Van Broeckhoven laboratory (VIB-UAntwerpen Center for Molecular Neurology) identified a new risk gene for Parkinson’s disease. Mutations in ATP10B resulted in loss of ATP10B protein. The function of the ATP10B gene was revealed by the Peter Vangheluwe lab (KU Leuven, Laboratory of Cellular Transport Systems). They identified ATP10B as a transporter for glucosylceramide, a lipid that plays a central role in Parkinson’s disease. Disease mutations disturb this function. Also, a reduced expression of ATP10B leads to neuronal loss and sensitizes neurons to environmental risk factors of Parkinson’s disease. Therefore, ATP10B is emerging as an interesting therapeutic target for Parkinson’s disease.

  • Proteins Involved in Glucose Metabolism Linked to Alzheimer's Disease

    April 14, 2020
    In the largest study to date of proteins related to Alzheimer’s disease, a team of researchers has identified disease-specific proteins and biological processes that could be developed into both new treatment targets and fluid biomarkers. The findings suggest that sets of proteins that regulate glucose metabolism, together with proteins related to a protective role of astrocytes and microglia — the brain’s support cells — are strongly associated with Alzheimer’s pathology and cognitive impairment.

  • Symptoms in ALS Mouse Model Improve with CRISPR Base Editing

    April 10, 2020
    ABOVE: Astrocytes (blue) have infiltrated the interior of the spinal cord, affecting neurons (yellow) in a mouse model of amyotrophic lateral sclerosis (ALS). In the study, the researchers developed an approach to deliver a CRISPR base editing system (green) to astrocytes in order to disable the expression of a mutant gene and reduce symptoms. COLIN LIM, UNIVERSITY OF ILLINOIS Base editors, which convert one nucleotide to another without a double-strand DNA break, have the potential to treat diseases caused by mutant genes. One drawback, though, is that the DNA that encodes CRISPR base editors is long—too long to fit in the adeno-associated viruses (AAVs) most commonly used for gene therapy. In a study published in Molecular Therapy on January 13, researchers split the DNA encoding a base editor into two AAV vectors and injected them into a mouse model of inherited amyotrophic lateral sclerosis (ALS).

  • Stroke: When the system fails for the second time

    March 20, 2020
    After a stroke, there is an increased risk of suffering a second one. Until now, it was known that if areas in the left hemisphere were affected during the first attack, language is often particularly impaired. In order to maintain the language capabilities, the brain usually drives up neighboring areas and briefly also the counterparts on the right side. However, it was unclear whether this would still happen after a second attack, and whether the activation of the right hemisphere areas is supportive for the regeneration at all. Scientists at the Max Planck Institute for Human Cognitive and Brain Sciences (MPI CBS) now found an answer by using virtual lesions. Indeed, it seems that the right hemisphere plays a constructive role in maintenance of function following big lesions as well as repeated strokes. These findings can help to improve therapy for those affected.
