These conditions are distinguished by the different types
of brain nerve cells that are first affected and by the symptoms that first appear.
They lead to
brain nerve cell death and the 1st nerves to get attacked are the nerves in the memory center of the brain.
Two kinds of mouse glial brain cells, microglia and astrocytes, making different versions of the APOE protein were grown
with brain nerve cells, or neurons, that make disease - causing forms of tau.
Mouse brain nerve cells (green) making a disease - causing version of the tau protein were grown in lab dishes with supporting brain cells called glia.
This is because the cells that detect odors, called olfactory receptor neurons (ORNs) have two remarkable properties: 1) they are nerve cells closely related to nerve cells in the brain, and 2)
unlike brain nerve cells, ORNs continually regenerate throughout a person's life.
Reporting online in Neuron, researchers at Washington University School of Medicine in St. Louis have identified a group of proteins that program a common type
of brain nerve cell to connect with another type of nerve cell in the brain.
For one, it would give them three specific biological markers to hone in on: The buildup of beta amyloid and tau proteins, which cause brain plaques associated with Alzheimer's, and
brain nerve cell death.
Used to manufacture the myelin sheath of
brain nerve cells, and therefore vital for cognitive function, intelligence, and quick thinking.
Studies have shown that it increases neuron plasticity — the ability of
brain nerve cells to take over some of the activities of brain cells destroyed or damaged by stroke.
