| We found that the amount of oxygen in the brain determines the type of vessel response triggered by astrocyte calcium signals. |
|
| An astrocyte listens in to the chemical conversation between neurons, soaking up neurotransmitters such as glutamate, the researchers showed. |
|
| However this illness is caused by astrocyte dysfunction. |
|
| His research work has been on around mechanisms of remyelination and demyelination as well as oligodendrocyte and astrocyte behaviour in clinical Multiple Sclerosis and its models. |
|
| Messages from nerve axons promote astrocyte development, and Dr. Wallace is the first to show that a morphogen called Sonic hedgehog is the signal go-between. |
|
| Other astrocyte projections connect to nearby capillaries, helping to bring oxygen-rich blood to the neurons. |
|
| The vast majority of astrocyte research is done using mice and rats, and has yielded important insights into the contributions of these cells to brain function. |
|
| Researchers from Ottawa University in Canada narrowed the effect down to a particular type of brain cell called an astrocyte. |
|
| When oxygen levels are high, similar to when the brain is inactive, astrocyte activation induces vasoconstriction, which would decrease blood flow. |
|
| In the brain, one type of cell that produces adenosine is the astrocyte, a star-shaped non-neuronal cell. |
|
| The astrocyte becomes important in later MS lesions, when it multiplies and eventually forms scar tissue that fills in where the oligos and myelin have been destroyed. |
|
| Recent studies have also determined that astrocyte dysregulation plays a central role in the pathogenesis of several disease processes, including brain metastasis. |
|
| When a neuron is damaged by a toxin such as in Parkinson's, the astrocyte population grows rapidly around the other neurons in order to protect them from further damage. |
|
| Differential modulation of astrocyte cytokine gene expression by TGF-beta. |
