Astrocyte morphogenesis is dependent on BDNF signaling via astrocytic TrkB.T1
Brain-derived neurotrophic factor (BDNF) is a critical growth factor involved in the maturation of the CNS, including neuronal morphology and synapse refinement.

Versatile and simple approach to determine astrocyte territories in mouse neocortex and hippocampus. [PDF]
BACKGROUND: Besides their neuronal support functions, astrocytes are active partners in neuronal information processing. The typical territorial structure of astrocytes (the volume of neuropil occupied by a single astrocyte) is pivotal for many aspects ...

The role of reactive astrocitose in the chronological evolution of traumatic brain injury [PDF]
Introduction and objectives. This study aims to investigate whether the cerebral modifications of posttraumatic reactive astrocitose can be considered an objective criterion for determining the age of traumatic cranio-cerebral lesions.

Astrocytic gliotransmission as a pathway for stable stimulation of post-synaptic spiking: Implications for working memory [PDF]
The brain consists not only of neurons but also of non-neuronal cells, including astrocytes. Recent discoveries in neuroscience suggest that astrocytes directly regulate neuronal activity by releasing gliotransmitters such as glutamate. In this paper, we consider a biologically plausible mathematical model of a tripartite neuron-astrocyte network.

Astrocyte-induced positive integrated information in neuroglial ensembles [PDF]
The Integrated Information is a quantitative measure from information theory how tightly all parts of a system are interconnected in terms of information exchange. In this study we show that astrocyte, playing an important role in regulation of information transmission between neurons, may contribute to a generation of positive Integrated Information ...

Human stem cell-derived astrocytes replicate human prions in a PRNP genotype-dependent manner. [PDF]
Prions are infectious agents that cause neurodegenerative diseases such as Creutzfeldt-Jakob disease (CJD). The absence of a human cell culture model that replicates human prions has hampered prion disease research for decades.
