A study in fruit fly models of autism reveals sleep disruption associated with the neurodevelopmental disorder is associated with elevated levels of serotonin. The origin of the higher levels of serotonin was discovered to be in glial cells in the blood-brain barrier.
Study sheds light on the brain chemistry involved in attention loss when a person drinks alcohol.
In mice lacking the GLT-1 transporter, cortical spreading depression, a neural excitation that underlies migraine pathology, occurred more frequently and spread more quickly. The findings provide potential new avenues for the treatment of migraines.
Glial cells not only control the speed of nerve conduction, but they also influence the precision of signal transduction.
Researchers demonstrate how a single injection of fibroblast growth factor 1 (FGF1) can restore blood sugar levels to normal for extended periods in rodent models of type 2 diabetes. Studies show how FGF1 affects specific neurons and perineuronal nets to help restore blood sugar levels to normal, thus sending diabetes into remission.
Adult neurons in fruitfly brains produce extra copies of their genomes to help prevent cell death caused by DNA damage.
Following a meal, astrocytes associated with POMC neurons in the hypothalamus alter their shape. After eating, glucose levels increase temporarily. Astrocytes detect the signal and react within one hour, causing POMC neurons to activate and promote the feeling of satiety.
Inflammation caused by opioid use to both the brain and gut may exacerbate symptoms of negative emotions associated with withdrawal. Targeting the inflammation could help alleviate the negative experiences of opioid withdrawal and prevent dependence.
Projection neurons have been implicated in the progression of multiple sclerosis. A new study reports projection neurons are damaged by immune cells. This damage could contribute to both atrophy and cognitive changes associated with the disease.
