BSE disease and the prion PrP that causes it.

eon I was searching for material on the meshwork for my program library research paper (NOT related to mad cow disease or prions!), I exclusively happened to come crossways this article, and I wanted to draw up about it, as we just talked about BSE unsoundness and the prion PrP that causes it. This upstarts article was stick on on Feb 14th, 06, on the Bioinfo Online website, and talks about how researchers at the whitehead Institute & Harvard Medical give instruction have discovered that the approach pattern form of this prion actually plays a role in a process called neuro agentsis, or mental institution of new neurons (cells that are responsible for the cognition function) by the headway. While the normal form of this protein was known, for years, to exist in human and numerous mammalian brains, no useful/beneficial function of the protein was understood, all the tantamount(predicate) though it is abundantly found in the human brain. some(prenominal) researche rs had belatedly found that PrP helps to preserve stem cells in blood, so this veritable teams (from Harvard & Whitehead) research investigated if there was any connection betwixt PrP and brain cells where these are mostly found. They used mice for the study, using 3 pigeonholings of these:1) where the PrP gene was disabled,2) where the gene was over-expressed (so large amounts of PrP were present, and,3) Control mice (normal)They found that when they place trumpeter cells of neuron cells from each of these, under appropriate nicety conditions:1) The precurosr cells from this group remained in that state for a long time, compared to the run across group (3), while Group (2) cells formed mature neurons to the highest spirit level immediately.

Their conclusion was that the rate at which neurons are formed is proportionate to the amount of PrP in the brain. But they found that while this lay was affected, the number of neurons formed in all the 3 groups was the very(prenominal)!Now, to continue the study, they are placing these mice in environments that are stimulation-rich which require a faster production of (their) new neurons. They are trying to overcharge if there is any difference in the way these groups of mice obturate perform/behave in these environments.
