This meant that every engineered
brain cell was now identical.
Zika virus's tricks for interfering with human
brain cell development may also be the virus's undoing.
Louis, found in mice and in mouse
brain cell cultures that the disease impairs the transfer of proteins to energy-making factories inside
brain cells.
But he added: "Our results suggest that small amyloid beta assemblies impact upon memory and normal
brain cell function but don't kill
brain cells.
Once a
brain cell has arrived at the new location, movement stops and the
brain cell forms connections with neighboring
brain cells.
Now, in an in vitro study using human brain stem cells, a team of German and Californian researchers shows how a specific PCB congener, PCB-118, can interrupt normal TH function and cause the premature differentiation of one type of
brain cell [EHP 113:871-876].
The physical phenomena produced by
brain cell firings can be measured with modern equipment, and the data can be correlated with various cognitive and emotional states of the subjects.
What's more, the average person already lives in a more stimulating environment than lab mice do, so it's not clear whether further improvement would make any difference in
brain cell numbers, she said.
When the mice were given antibodies that prevented transthyretin from interacting with the [beta]-amyloid protein, the mice showed typical
brain cell death.
Developing the capability to induce adult stem cells to differentiate into cells that secrete a battery of neurotrophic factors is a major step forward because of the important role that these factors are believed to have in
brain cell survival and growth," said Yoram Drucker, Principal Executive Officer of BrainStorm.
Those that took higher doses of nicotine also experienced the most
brain cell death.
Each infected
brain cell suffered a one-two punch when the virus simultaneously shut down activity of a protein called p53--which normally stops cells from growing out of control--and activated one of two cancer-promoting proteins.
