Alzheimer's proteins may work together to cause brain damage

Alzheimer's proteins may work together to cause brain damage
16th May 2011

Two proteins involved in Alzheimer's disease combine to adversely affect the energy centres of brain cells, research has revealed.

A study published online in journal Neurobiology of Aging found that pathological forms of two proteins - amyloid beta and tau - could work together to damage the survival of brain cells.

Gail Johnson, corresponding author, explained that the notion that the two proteins may work together to the detriment of brain cells is a long standing one.

"The precise relationship between the two pathologies is unclear, but there may be a synergy between the two when it comes to their effects on mitochondria in Alzheimer disease," she continued.

Meanwhile, a study published in journal NeuroImage said that Alzheimer's disease could be better understood through the use of a novel brain scanning method.

Known as SAXS-CT, the brain imaging technique maps the myelin sheaths of nerve cells, the damage of which is associated with such conditions.
