Reactive astrocyte nomenclature, definitions, and future directions

…, EM Hol, MG Holt, M Iino, KV Kastanenka… - Nature …, 2021 - nature.com
Reactive astrocytes are astrocytes undergoing morphological, molecular, and functional
remodeling in response to injury, disease, or infection of the CNS. Although this remodeling was …

[HTML][HTML] Slow wave sleep is a promising intervention target for Alzheimer's disease

…, I Timofeev, BJ Bacskai, KV Kastanenka - Frontiers in …, 2020 - frontiersin.org
Alzheimer’s disease (AD) is the major cause of dementia, characterized by the presence of
amyloid-beta plaques and neurofibrillary tau tangles. Plaques and tangles are associated …

A roadmap to integrate astrocytes into Systems Neuroscience

KV Kastanenka, R Moreno‐Bote, M De Pittà, G Perea… - Glia, 2020 - Wiley Online Library
Abstract Systems neuroscience is still mainly a neuronal field, despite the plethora of evidence
supporting the fact that astrocytes modulate local neural circuits, networks, and complex …

[HTML][HTML] Cerebrospinal fluid amyloid-β 42/40 ratio in clinical setting of memory centers: a multicentric study

…, K Peoc'h, B Sablonnière, KV Kastanenka… - Alzheimer's research & …, 2015 - Springer
Introduction The cerebrospinal fluid (CSF) biomarkers amyloid-β (Aβ), tau and phosphorylated
tau (p-tau181) are now used for the diagnosis of Alzheimer’s disease (AD). Aβ40 is the …

Immunotherapy with aducanumab restores calcium homeostasis in Tg2576 mice

KV Kastanenka, T Bussiere, N Shakerdge… - Journal of …, 2016 - Soc Neuroscience
Calcium homeostasis plays a major role in maintaining neuronal function under physiological
conditions. Amyloid-β (Aβ) initiates pathological processes that include disruption in …

[HTML][HTML] Optogenetic restoration of disrupted slow oscillations halts amyloid deposition and restores calcium homeostasis in an animal model of Alzheimer's disease

KV Kastanenka, SS Hou, N Shakerdge, R Logan… - PloS one, 2017 - journals.plos.org
Slow oscillations are important for consolidation of memory during sleep, and Alzheimer’s
disease (AD) patients experience memory disturbances. Thus, we examined slow oscillation …

[HTML][HTML] Reduced excitatory neuron activity and interneuron-type-specific deficits in a mouse model of Alzheimer's disease

…, D Gerashchenko, BJ Bacskai, KV Kastanenka - Communications …, 2022 - nature.com
Alzheimer’s disease (AD) is characterized by progressive memory loss and cognitive
decline. These impairments correlate with early alterations in neuronal network activity in AD …

[HTML][HTML] Optogenetic targeting of astrocytes restores slow brain rhythm function and slows Alzheimer's disease pathology

…, A Araque, E Galea, BJ Bacskai, KV Kastanenka - Scientific reports, 2023 - nature.com
