Astrocytes of the optic nerve exhibit a region-specific and temporally distinct response to elevated intraocular pressure

open access: yesMolecular Neurodegeneration, 2023
Background The optic nerve is an important tissue in glaucoma and the unmyelinated nerve head region remains an important site of many early neurodegenerative changes. In both humans and mice, astrocytes constitute the major glial cell type in the region,

Astrocytes: Powering Memory [PDF]

open access: yesCell, 2011
Creating long-term memory requires a cellular program in neurons involving gene expression, protein synthesis, and formation of new synaptic connections. Suzuki et al. (2011) show that astrocytes, glial cells of the brain, play a necessary role in this program by converting glycogen to lactate and transporting it to neurons.

Conducting Polymer Microelectrode Arrays for Simultaneous Electrophysiology and Advanced Brain Imaging

open access: yesAdvanced Functional Materials, EarlyView.
A flexible micro‐electrocorticography array with PEDOT:SS electrodes is shown to be compatible with ultra‐high magnetic field MRI up to 9.4 T. Multimodal brain monitoring is demonstrated by performing simultaneous blood oxygen level‐dependent functional MRI in parallel with electrophysiology.

New Insights into GFAP Negative Astrocytes in Calbindin D28k Immunoreactive Astrocytes

open access: yesBrain Sciences, 2018
Glial fibrillary acidic protein (GFAP) is commonly used as a specific marker for the identification of astrocytes. Nevertheless, it is known from the literature that astrocytes in situ in contrast to cultured astrocytes may feature lower levels of GFAP ...

Biomimetic Design of Biocompatible Neural Probes for Deep Brain Signal Monitoring and Stimulation: Super Static Interface for Immune Response‐Enhanced Contact

open access: yesAdvanced Functional Materials, EarlyView.
Ultrathin, flexible neural probes are developed with an innovative, biomimetic design incorporating brain tissue‐compatible materials. The material system employs biomolecule‐based encapsulation agents to mitigate inflammatory responses, as demonstrated through comprehensive in vitro and in vivo studies.

Reactive Astrocytes in Neurodegenerative Diseases

open access: yesAging and Disease, 2019
Astrocytes, the largest and most numerous glial cells in the central nervous system (CNS), play a variety of important roles in regulating homeostasis, increasing synaptic plasticity and providing neuroprotection, thus helping to maintain normal brain ...

Astrocytes in Flavivirus Infections [PDF]

open access: yesInternational Journal of Molecular Sciences, 2019
Virus infections of the central nervous system (CNS) can manifest in various forms of inflammation, including that of the brain (encephalitis) and spinal cord (myelitis), all of which may have long-lasting deleterious consequences. Although the knowledge of how different viruses affect neural cells is increasing, understanding of the mechanisms by ...

3D In Vitro Glioma‐Neuron‐Astrocyte Biomimetic Composites Recapitulate Key Molecular Mechanisms Linked to Glioblastoma Multiforme Pathophysiology

open access: yesAdvanced Functional Materials, EarlyView.
Glioblastoma multiforme is the most devastating and incurable brain tumor. To better study this disease, a 3D model is developed using a hyaluronic acid‐based hydrogel combined with a multicellular approach. This model recapitulates in vivo brain stiffness, cell‐extracellular matrix and cell‐cell interactions and the tumor's hijacking function with the

Tumor-associated reactive astrocytes aid the evolution of immunosuppressive environment in glioblastoma

open access: yesNature Communications, 2019
Reactive astrocytes evolve after brain injury, inflammatory and degenerative diseases, whereby they undergo transcriptomic re-programming. In malignant brain tumors, their function and crosstalk to other components of the environment is poorly understood.

Protective Functions of Reactive Astrocytes Following Central Nervous System Insult

open access: yesFrontiers in Immunology, 2020
Astrocytes play important roles in numerous central nervous system disorders including autoimmune inflammatory, hypoxic, and degenerative diseases such as Multiple Sclerosis, ischemic stroke, and Alzheimer’s disease. Depending on the spatial and temporal
