When the body realizes it is inaccurately producing proteins, it responds by shutting down protein production. This is one of the mechanisms the body uses to stop the spread of viruses in the body. If the virus is targeting protein, then halting the production will slow down or stop the spread of the virus. Typically, this is a short-term problem.
In patients who have a neuro-degenerative disease such as a prion disease or Alzheimer's, the body builds up of proteins which are not correctly made. The body shuts down the production of proteins but does so for a long time which leads to a reduction of brain cells. Brain cells which have died are not replaced.
British scientists have announced that a drug which treats this problem is showing favorable results in mice for multiple neuro-degenerative diseases.
