scientific picture. A XNUMXD model system of human neurons in a dish. In green and purple: nerve cells expressing a protein that is defective in the ubiquitin system. As a result of this expression, the pathology that characterizes Alzheimer's patients is created - the formation of amyloid clusters (in red) outside the cells

Technion researchers have identified the mechanism leading to the formation of protein aggregates involved in the development of Alzheimer's disease

  • One response
Toxic proteins accumulate in the brains of Alzheimer's patients. In the familial Alzheimer's patients, the accumulation mechanism is clear since there is a circumstantial relationship between the mutations and the identity of the defective proteins. In the random disease, on the other hand, the reason for the accumulation of the defective proteins was unknown

Professor Hermona Sorek, one of the world's leading researchers of gene expression in the brain, was able to find, in collaboration with her research colleagues, a molecular mechanism that occurs in the brains of Alzheimer's patients, which does not occur in men and which explains the acceleration of cognitive deterioration in Alzheimer's patients

Stem cells derived from the placenta are able to reach damaged tissues in the brains of drug addicts and initiate a rehabilitation process in them. The innovative treatment may solve one of the most difficult challenges in the field of detoxification: the difficulty of addicts to detach from the memory that brings them back again and again to the drug
Brain regions selected for temperature measurement using magnetic resonance spectroscopy are shown as overlays on standard MSR scans of the brain in different planes. 80 regions were selected in the cerebrum (shown in top view, top left, and side view, top right) and grouped into four concentric layers (top left). One region was selected in the hypothalamus (Hypo, shown in top, side and front view, bottom left of center) and one region in the thalamus (Thal, shown in front view, bottom right). The hypothalamus is an important area in the regulation of many things including temperature, sleep and biological clock. Credit: Nina Rzechorzek/Edinburgh Imaging/Brain

Pioneering Israeli development will facilitate surgeries for Parkinson's patients

Researchers at the Hebrew University and the Hadassah Medical Center have developed a method of anesthesia that will allow Parkinson's patients to undergo surgery that significantly alleviates the disease even in a state of confusion. Prof. Hagai Bergman: "This is a significant development for patients who, until today, most had to undergo brain surgery in an alert state"

The researchers found that the activation process of stem cells in the brain responsible for the production of neurons (nerve cells) is not random but ordered and coordinated. According to them, the findings are of great importance for understanding the normal development of the brain. The findings may form the basis for the development of future treatments for brain cancer, for degenerative diseases of the brain such as Alzheimer's and Parkinson's, and for various brain injuries
