New research supports brain cell transplantation as a treatment for some disorders

Raw Story  

Astrocytes — named for their star-like shape — are a type of brain cell as abundant as neurons in the central nervous system, but little is known about their role in brain health and disease. A functioning brain requires healthy astrocytes, and finding strategies to heal or replace damaged astrocytes could help in the treatment of neurological diseases. We found …

Brain cell transplants might be key to beating Alzheimer's, doctors claim

Daily Mail  

Alzheimer's is a cruel disease that blights the lives of millions worldwide, slowly robbing them of their memories and independence. Now, scientists at McGill University, Canada, may have found a key to treating the neurological disease — by transplanting brain cells. Scientists believe that replacing damaged astrocytes could help restore some of the lost brain function seen in Alzheimer's, as …

Head injuries could be risk factor for developing brain cancer

Hindustan Times  

A very uncommon but frequently aggressive type of brain tumour called a glioma may be caused by damage, according to key molecular research from the UCL Cancer Centre. Head injuries could be risk factor for developing brain cancer Although there may be a connection between head trauma and an increase in brain tumour incidence, the evidence is conflicting. She said: …

High fat diet could reduce ability to regulate food intake: Study

Hindustan Times  

Regularly eating a high-fat/calorie diet could reduce the brain's ability to regulate calorie intake. High fat diet could reduce ability to regulate food intake: Study The researchers from Penn State College of Medicine, US, suggest that calorie intake is regulated in the short-term by cells called astrocytes that control the signalling pathway between the brain and the gut. Around 10-14 …

A New Study Describes How COVID-19 Damages The Brain

News 18  

Once infected, astrocytes exhibited altered levels of metabolites used to fuel neurons and neurotransmitter production, and the infected cells secreted neurotoxic molecules. In this study, we provide evidence that severe acute respiratory syndrome coronavirus 2 is found in the human brain, where it infects astrocytes and to a lesser extent, neurons. We also show that astrocytes are susceptible to SARS-CoV-2 …

COVID-19 damages the brain cells? Here's what a new study found out

Hindustan Times  

A study shows how SARS-COV-2 infects brain cells called astrocytes, causing structural changes in the brain. Here's what a new study found out Daniel Martins-de-Souza and colleagues used MRI to compare brain structure in 81 study participants recovering from a mild COVID-19 infection and 81 healthy individuals. In this study, we provide evidence that severe acute respiratory syndrome coronavirus 2 …

Hindustan Times  

In a new study at Tufts University researchers came across a previously unknown function performed by a cell type that contains almost half of all cells in the brain. Nearly half of the brain's cells execute new functions, according to researchers The findings of the research were published in the journal 'Nature Neuroscience'. The scientists say this discovery in mice …

LA Times  

Scientists experimenting in the lab have found that the coronavirus that causes COVID-19 is capable of infecting two types of brain cells — neurons and astrocytes. COVID-19 is best known as a respiratory disease, but for many victims, it also triggers an array of problems including memory lapses, fatigue and a certain sluggish, fuzzy feeling often referred to as “brain …

The gene that increases the risk of Alzheimer’s disease can increase a person’s susceptibility to and severity of Covid-19, researchers say. The study, published in journal ‘Cell Stem Cell’, suggests that the gene ApoE4 showed a higher susceptibility to SARS-CoV-2 infection. “Our study provides a causal link between the Alzheimer’s disease risk factor ApoE4 and Covid-19 and explains why some …

Brain estrogen levels key to protect brain in stroke-like conditions: Study

Hindustan Times  

When the brain is not getting enough oxygen, neurons produce estrogen in both males and females, which hyperactivates another brain cell type called astrocytes to step up their usual support and protect brain function. In the face of low brain oxygen that can occur with stroke or other brain injuries, these astrocytes, star-shaped brain cells that help give the brain …
