BSE disease and the prion PrP that causes it.

eon I was searching for material on the network for my program library research paper (NOT related to mad cow disease or prions!), I honest happened to come crosswise 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 recents 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 observe that the figure form of this prion actually plays a role in a process called neurobrokersis, or mental institution of new neurons (cells that are responsible for the cognition function) by the flair. 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 equivalent though it is abundantly found in the human brain. some(prenominal) researchers had recently found that PrP he lps to preserve stem cells in blood, so this topical 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 assemblages 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 antecedent 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 point 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 put down was affected, the number of neurons formed in all the 3 groups was the aforesaid(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 nail if there is any difference in the way these groups of mice close up perform/behave in these environments.
