A single human cell teems with as many 100,000 different proteins. Actin is one of the most abundant and essential of them all. This protein forms into filaments that help make up the skeleton of cells, giving them shape. ...

One of the hallmarks of Alzheimer's disease is the presence of neurofibrillary tangles in the brain. These tangles, made of tau proteins, impair neurons' ability to function normally and can cause the cells to die.
