Investigation of Neuropeptide Y as a metabolic marker and its effects on adipose vasculature and brainstem astrocytes [PDF]
, 2015 Subsets of morbidly obese patients do not appear to exhibit the expected comorbidities, as well as the fact that heightened sympathetic nervous system (SNS) activity has been known to affect metabolism.

The Role of Astrocytes in Astrocytes Alzheimer’s Disease
Annals of the Academy of Romanian Scientists Series on Biological Sciences, 2020 "Astrocytes are highly specialized glial cells and play a crucial role in neuronal functionality and brain functional integrity. Although research on Alzheimer’s disease has been concentrated mainly on the role of neurons, increasing evidence comes to light marking the important role of astrocytes in the pathophysiology of Alzheimer’s disease ...

Amines, Astrocytes, and Arousal [PDF]
Neuron, 2017 Amine neurotransmitters, such as noradrenaline, mediate arousal, attention, and reward in the CNS. New data suggest that, from flies to mammals, a major mechanism for amine transmitter action is to raise astrocyte [Ca2+]i and release gliotransmitters that modulate neuronal activity and behavior.

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Changes in intracellular calcium and glutathione in astrocytes as the primary mechanism of amyloid neurotoxicity [PDF]
, 2003 Although the accumulation of the neurotoxic peptide {beta} amyloid ({beta}A) in the CNS is a hallmark of Alzheimer's disease, the mechanism of {beta}A neurotoxicity remains controversial.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Central nervous system (CNS) inflammatory demyelinating syndromes, including multiple sclerosis (MS), aquaporin‐4 antibody–positive neuromyelitis optica spectrum disorder (AQP4 + NMOSD), and myelin oligodendrocyte glycoprotein (MOG) antibody–associated disease (MOGAD), occasionally overlap.

Dimethyl Fumarate, But Not Rituximab, Reduces Serum GFAP Levels and PIRMA in Relapsing–Remitting MS
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Serum neurofilament light chain (sNfL) and glial fibrillary acidic protein (sGFAP) levels are believed to reflect mainly acute and chronic disease processes in multiple sclerosis (MS), respectively. In this study, we investigated whether dimethyl fumarate (DMF) and rituximab (RTX) differentially affect these biomarkers.

Transcriptional analysis of astrocytes reveals protective functions during remyelination [PDF]
, 2020 In Multiple Sclerosis (MS), the insulating membrane that ensheaths axons termed myelin, is lost by a process known as demyelination. Initial regeneration of myelin, termed remyelination, restores neuronal function.
