«The key point here is that we can say something about how the gene acts to influence this behavior — that is, is by functioning as a chemical messenger in cells that control this behavior in the brain.

Further study revealed that these so - called immune proteins are actually present on the surface of certain nerve cells, but that they functioned differently in the brain than they did in the rest of the body; rather than scouting for germs, they influenced signals sent between neurons.

We're funding researchers to investigate how drugs alter what genes are activated such that they modify the function of the cells, and how this, in turn, modifies the functions of brain circuits, and how that modifies behavior.

«We still don't know very much about how individual cells in the brain coordinate the activity of higher - level function that defines us as humans,» he says.

The study is also the latest in recent years to implicate glial cells in important brain functions.

Until recently it has been difficult to study the role of glial cells in controlling appetite or any other brain function, because scientists haven't developed many techniques for silencing or stimulating these cells, as they have for neurons.

«I was very curious at that point what glial cells would be doing in the hypothalamus, since glial cells have been shown in other brain areas to have an influence on regulation of neuronal function,» she says.

There is more and more evidence to point to the importance of glial cells in modulating neuronal function and in mediating brain disorders,» says Guoping Feng, the James W. and Patricia Poitras Professor of Neuroscience.

Published in Molecular Neurobiology, the study led by Dr Elodie Siney under the supervision of Dr Sandrine Willaime - Morawek, Lecturer in Stem Cells and Brain Repair at the University, analysed how enzymes called ADAMs affect the movement and function of the human tumor cCells and Brain Repair at the University, analysed how enzymes called ADAMs affect the movement and function of the human tumor cellscells.

It has been particularly difficult to measure changes in electrical functions of cells grown within Organ Chips that are normally electrically active, such as neuronal cells in the brain or beating heart cells, both during their differentiation and in response to drugs.

The research, published in the current issue of the journal Science, demonstrates that brain cells, known as astrocytes, which play fundamental roles in nearly all aspects of brain function, can be adjusted by neurons in response to injury and disease.

Our brain contains billions of cells, each of which need to communicate between each other in order to function properly.

Astrocytes are star - shaped cells in our brain that surround brain neurons, and neural circuits, protecting them from injury and enabling them to function properly — in essence, one of their main roles is to «baby - sit» neurons.
