When β-amyloid proteins build up inside cells, they start to stick together, or aggregate, in clumps, which is detrimental to the health of the cell. These damaging clumps, which are known as plaques, are found in the brains of both individuals with Down’s syndrome and Alzheimer’s disease and are thought to be responsible for the pathology of Alzheimer’s.
Another important discovery was that deleting the SNX27 gene promoted the production of β-amyloid and also brain cell death. Furthermore, increasing SNX27 levels in mouse models of Alzheimer’s reduced the levels of β-amyloid in the brains of these mice.
To take this further, the researchers are now searching for molecules that can reduce the levels of miRNA-155, which will hopefully restore normal levels of SNX27. If successful, this may eventually lead to new treatment avenues to help reduce brain cell loss in individuals with both Alzheimer’s and Down’s syndrome.
