Utilizing innovative high-resolution imaging, this study is the first to link age-related cognitive decline and reduced cerebral blood flow to structural and functional degradation of Principal ...
A 74-year-old man with an unremarkable medical history noted a progressive gait disorder in the months prior to admission. His wife recalled increased sleepiness and loss of initiative. After having ...
When the brain is injured in some way, a wide range of biochemical changes are triggered that can affect crucial brain cells known as astrocytes. They are a type of glial cell, and brain injuries ...
Scientists at UT Southwestern have identified the protein GADD45G as a master regulator of reactive gliosis, a damaging process in neurodegenerative diseases like Parkinson’s and Alzheimer’s, offering ...
Astrocytes are crucial for brain homeostasis and synaptic activity under healthy conditions, and are activated during neuroinflammation, neural damage and neurodegeneration, such as in Alzheimer's ...
The widely accepted concept of the neurovascular unit suggests that proper brain function relies on dynamic communication and homeostatic signaling among neurons, glial cells, and vascular compartment ...
Putative retinal gliosis refers to changes in the retina caused by the activation of glial cells, which are support cells that become activated when there is damage or disease in the retina. In this ...
Obesity associated with hypothalamic dysfunction was initially described in patients with craniopharyngioma. Hypothalamic obesity may also result from brain radiation, infection (eg, tuberculosis), ...
This story is part of a series on the current progression in Regenerative Medicine. This piece discusses advances in brain-machine interfaces. In 1999, I defined regenerative medicine as the ...
