Effects of 660-nm LED photobiomodulation on drebrin expression pattern and astrocyte migration
Scientific Reports, 2023 Photobiomodulation (PBM) is a therapeutic tool that uses red or near-infrared light in medical applications. It’s applications in both central (CNS) and peripheral nervous system (PNS) are widely studied.

Long‐term hippocampal alterations and cognitive impairment in a murine model of surgical sepsis
FEBS Open Bio, EarlyView.Using a mouse model of surgical sepsis, we tested long‐term memory and analyzed the transcriptome of single cells isolated from the hippocampus. Survivor mice showed worse memory, loss of certain brain cell subpopulations, and abnormal immune cell activity—suggesting that post‐sepsis brain alterations may be linked to cognitive deficits.

Astrocyte morphogenesis is dependent on BDNF signaling via astrocytic TrkB.T1
eLife, 2019 Brain-derived neurotrophic factor (BDNF) is a critical growth factor involved in the maturation of the CNS, including neuronal morphology and synapse refinement.

Astrocytes in Flavivirus Infections [PDF]
International 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 ...

FEBS Open Bio, EarlyView.The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Brain SciencesTinnitus is correlated with anomalies of neural plasticity and has been found to be affected by inflammatory status. The current theories on tinnitus, although still somewhat incomplete, are based on maladaptive plasticity mechanisms. Astrocytes play a major role in both neural responses to inflammation and plasticity regulation; moreover, they have ...

Journal of Integrative Neuroscience, 2022 The cellular, molecular and physiological basis of cognition has proved elusive until emerging studies on astrocytes. The appearance of a deliberate aggregating element in cellular neurophysiology was difficult to satisfy computationally with excitatory and inhibitory neuron physiology alone.

Mechanosensory Signaling in Astrocytes [PDF]
The Journal of Neuroscience, 2020 Mechanosensitivity is a well-known feature of astrocytes, however, its underlying mechanisms and functional significance remain unclear. There is evidence that astrocytes are acutely sensitive to decreases in cerebral perfusion pressure and may function as intracranial baroreceptors, tuned to monitor brain blood flow.

FEBS Open Bio, EarlyView.Repair of neuronal DNA damage in Alzheimer's disease by KCL‐286. (A) Amyloid‐β oligomers and plaques impair neuronal DNA repair pathways, leading to DNA double‐strand breaks and glial activation. (B) KCL‐286 activates RARβ/RXR signalling via retinoic acid response elements (RAREs), associated with increased BRCA1 expression, enhanced DNA repair and ...
