Researchers have discovered a protein that they claim is the missing link to the development of Alzheimer’s disease. They found that blocking this protein with an existing drug can restore memory in mice with brain damage that mimics the disease. The findings could offer hope of developing drugs to slow the degenerative illness.'What is very exciting is that of all the links in this molecular chain, this is the protein that may be most easily targeted by drugs,' said the study’s senior author Stephen Strittmatter at Yale School of Medicine.'This gives us strong hope that we can find a drug...
