SerbiaScientists have discovered a mechanism by which Alzheimer’s disease spreads through the brain, identifying a protein called Arc that facilitates the transfer of toxic tau proteins between neurons. The study, conducted by researchers at the University of Utah, found that while Arc normally helps neurons communicate, it also enables the spread of toxic tau from damaged to healthy cells. Published in the journal 'Cell', the research suggests potential new therapeutic targets that could slow disease progression rather than just treating symptoms. The findings show that blocking Arc might not be effective due to its protective role in early stages of the disease. Researchers emphasize the need for further studies, particularly in humans, before these discoveries can lead to treatments.
Tendenz-Einschätzung (Mitte): The article presents scientific research without overt ideological framing. It discusses medical findings and their implications objectively, focusing on the mechanisms of disease and potential therapies without taking a political stance.
