Process Discovered That Saves Injured Nerve Cells And Helps Prevent Brain Damage

In Brief
Scientists found that brain cells called astrocytes send their own energy-producing mitochondria to struggling nerve cells to help recover from injuries such as strokes. Similar findings have been made in lab dishes as well as in mice brains.

You Get By With A Little Help 

Here’s another interesting thing about the human body – a new study published in Nature found that, when nerve cells are under duress, their other cell friends help them out.
Scientists say struggling nerve cells get a little help in the form of energy-producing mitochondria from brain cells. These are called astrocytes, star-shaped glial cells which assist neurons in recovering after injuries such as strokes. Astrocytes take in and get rid of neurons’ discarded mitochondria. It produces mitochondria and pushes it out into “the soup that surrounds cells.” During a stroke or when starved of glucose and oxygen, neurons take in the astrocyte-made organelles.

The Gift That Keeps On Giving

Scientists also found organelles moving into damaged cells in other parts of the body, including the lungs, heart and liver. Neuroscientist Jarek Aronowski of the University of Texas Health Science Center at Houston says the astrocyte-to-neuron transfer is quite shocking. Nobody knew brain cells could be so magnanimous!
Neurons who received mitochondria fared better in a starvation diet than those without. Researchers also noticed that, without the extra mitochondria to help, the neurons were less resilient to the harsh conditions in the test dishes.
Study coauthor Eng Lo of Massachusetts General Hospital and Harvard Medical School says their study is still in its early stages, but he hopes that a deeper understanding of this process might ultimately point out new ways to protect the brain from damage. Still, researchers were able to observe these findings outside of a testing dish. Similar observations were made in lab mice. There is much more research to be done but there could be some pretty exciting implications for even existing treatments.

Explainer: The nico-teen brain

Explainer: The nico-teen brain The adolescent brain is especially vulnerable to the addictive effects of nicotine BY  TERESA SHIPLEY FELDHAUSEN 7:00AM, AUGUST 19, 2015 Nicotine (black triangle towards center left) tricks the nerve cell (neuron) into sending a message to release more dopamine (yellow dots). Those molecules enter the space (synapse) between one nerve cell and the next. When they get picked up by neighboring cells, this gives users a feel-good high. It also creates the risk of addiction and other health problems.  EMail Print Twitter Facebook Reddit Google+ NATIONAL INSTITUTE ON DRUG ABUSE, ADAPTED BY J. HIRSHFELD Nicotine is the addictive chemical in tobacco smoke and e-cigarette vapors. And doctors say the teenage brain is no place for it to end up. Nicotine can reach the brain within seven seconds of puffing on a cigar, hookah, cigarette or electronic cigarette.
