Going hand-in-hand with decreased proteins in the brain, amyloid plaques are also commonly found in the brains of Alzheimer’s patients.
However, a new study has found that it is not the amyloid plaques themselves that are directly linked to Alzheimer’s disease, but rather the decreased proteins in the brain that precede the formation of the plaques.
The study, conducted by researchers at the University of British Columbia, looked at the brain tissue of both Alzheimer’s patients and healthy individuals.
They found that in the brains of Alzheimer’s patients, there was a significant decrease in a class of proteins known as kinesins.
Kinesins are responsible for transporting other proteins within cells, and the researchers believe that their reduced levels in the brain may prevent the proper clearance of amyloid beta, leading to its buildup and the formation of plaques.
While the study does not necessarily rule out a role for amyloid plaques in the development of Alzheimer’s disease, it does suggest that they are not the primary cause.
Instead, it is the reduced levels of kinesins and other proteins that may be responsible for the onset of the disease.
Further research is still needed to confirm these findings, but they provide a new and potentially important avenue of investigation into the cause of Alzheimer’s disease.
Recent research has suggested that decreased levels of proteins, not amyloid plaques, may be responsible for Alzheimer’s disease.
Scientists have long believed that amyloid plaques, deposits of a protein fragment that build up in the brains of Alzheimer’s patients, are responsible for the cognitive decline seen in the disease. However, recent research has suggested that decreased levels of proteins, not amyloid plaques, may be responsible for Alzheimer’s disease.
One study, published in the journal Nature, found that mice that lacked a protein called RbAp48 had lower levels of proteins involved in memory and learning. The mice also showed signs of Alzheimer’s disease, including cognitive decline and neurodegeneration.
Another study, published in the journal Neuron, found that when levels of the protein Fyn were reduced, levels of another protein involved in memory and learning, calledARC, were also reduced. The mice in this study also showed signs of cognitive decline and neurodegeneration.
These studies suggest that decreased levels of proteins, not amyloid plaques, may be responsible for Alzheimer’s disease. This is an important finding, as it may help to develop new treatments for the disease.
