Amyloid-beta accumulation in aggregates is thought to be the leading cause of Alzheimer's disease. Despite the many advances in the field, it is still challenging to diagnose Alzheimer's in the early stages of the disease. Therefore, there is a need to find reliable biomarkers that can be easily detected from the very onset of the disease. Here, a new method based on proteomic profiling is used to identify serum proteins related to amyloid-beta plaque formation to be used as biomarkers. The results show that there are effectively amyloid beta-related serum proteins. Among them, a considerable percentage are unique for amyloid plaque particles in Alzheimer's serum compared to cholesterol, alpha-synuclein and tau plaque particles. Additionally, some of them were also able to form amyloid-beta plaques in vitro. Overall, the researchers show a new, potentially non-invasive, method to easily detect proteins and identify proteins related to amyloid-beta plaque formation to be used as biomarkers.
