One of the many diseases caused by faulty cell-to-cell communication is Alzheimer’s disease. This disease causes many cells in the brain to die. Therefore, as more and more of the cells die, it causes the brain to shrink. What causes the brain cells to die, which then causes the brain to contract, is the unusual twist of the protein called tau. Tau is a protein in the brain that delivers nutrients and other important elements to the brain cells. The effect of the twisted protein inhibits the brain cells to keep their homeostasis and get their essential materials that are suppose to be transported by the protein to keep them alive. Another factor in that contributes to the brain cells to die are clumps of the protein, beta-amyloid, which creates
