Astrocytes, a sub-population of glial cells with a distinctive star-like shape, are known to play a vital role in numerous neuronal functions, including synaptic support, the regulation of energy metabolism, and the control ...
Environment moulds behaviour - and not just that of people in society, but also at the microscopic level. This is because, for their function, neurons are dependent on the cell environment, the so-termed extracellular matrix. ...

Astrocytes form large networks of interconnected cells in the central nervous system. When these cell-to-cell couplings are disrupted in the brain of adult mice, the animals are no longer able to store spatial information. ...

Though Alzheimer's disease (AD) is a common and fatal neurodegenerative brain disorder, most AD treatments are not making much headway in adressing its cause. Many AD drugs have targeted the elimination of beta-amyloid (Aβ) ...
