Scientists uncover a new role for blood-brain barrier in neuron function and damage

2022-08-18 - 2022-08

Researchers have made a surprising discovery linking Delta/Notch signaling in subperineurial glia (SPG) to the regulation of nerve ensheathment and neurotransmitter release at the Drosophila neuromuscular junction (NMJ). SPG, the counterpart of the endothelial layer in the vertebrate blood-brain barrier, form the key cellular layer that is critical for axonal ensheathment and the blood-brain barrier in Drosophila. The results provide a mechanistic insight into the biology of barrier function and glia-neuron interactions.

How the brain gathers threat cues and turns them into fear Findings could lead to treatments for fear-related disorders

Scientists have uncovered a molecular pathway that distills threatening sights, sounds and smells into a single message: Be afraid. A molecule called CGRP enables neurons in two separate areas of the brain to bundle threatening sensory cues into a unified signal, tag it as negative and convey it to the amygdala, which translates the signal into fear. The research may lead to new therapies for fear-related disorders such as post-traumatic stress disorder (PTSD) or hypersensitivity disorders such as autism, migraines and fibromyalgia.

Study reveals altered brain dynamics in those with unresponsive arousal syndrome, previously known as “vegetative state”, and in those with minimally conscious state.

A study by the Human Brain Project (HBP), led by scientists from the University of Liège (Belgium), has explored new techniques that may help distinguish between two different neurological conditions in patients with severe brain damage and or in a coma. The results of this study have just been published in open access in the journal e Life.
