In the journal named NATURE, researchers provided evidence that the hormones which are extracted from dead human brains and injected into healthy ones, can be the source of Alzheimer’s disease because certain protein fragments trigger the formation of Alzheimer’s-causing plaques which in later stages, become the reason behind Alzheimer’s.
A new study said that this disease occurs when a person is receiving the protein is greater quantity. But it does not mean that Alzheimer’s disease is transmittable or contagious, the authors and independent commentators stressed. The disease can be transferred via the exchange of affected tissues.
Co-author John Collinge of University College London, aforementioned that, “This relates to a very special situation where people have been injected with essentially extracts of human tissue,”
“I don’t think there needs to be any alarm that we’re saying in any way that you can catch Alzheimer’s disease.”
Collings and his team investigated the brains of eight individuals who had received the protein fragments as a sort of treatment in their child hood to cure dwarfism (a condition in which a person is unusually or abnormally low stature or small size). This investigation has been done while conducting research on some unrelated disease.
Pituitary gland was the organ from where hormones had been plucked from thousand of dead animals. But in 1985 after the realization of the fact that this extraction is becoming the reason of transmitting unusually or abnormally low stature or small size.
“We should think about whether there might be accidental routes in which these diseases might be transmitted by medical or surgical procedures.”
As mention above that Collins and his team transmitted the protein fragment in eight individuals for study purpose, 7 of them had Alzheimer’s-linked amyloid beta (Abeta) fragments deposited in their brains, whereas 4 of these had high concentration of the proteins. All of the subjects died out of this illness.
