In the search for answers about Alzheimer’s disease, researchers are taking a close look at the immune system of the brain. A new study uncovers how a key immune cell, called a microglia, might be the ...

During development, there are known sex-related differences in how microglia function. But into adulthood, there was thought to be less variation in how they behave. Microglia maintain neuronal ...

A collision happens. Someone is hurt, a head injury, a concussion. Just as the first responders arrive to help the person, inside the brain, another “crew” of responders is busy clearing debris and ...

While amyloid β plaques are hallmarks of Alzheimer’s disease (AD), recent research suggests that they aren’t the only players in the neurodegenerative disorder. Genome-wide association studies and RNA ...

Microglia are a specialized type of immune cell that accounts for about 10% of all cells within the brain and spinal cord. They function by eliminating infectious microbes, dead cells, and aggregated ...

Using Alzheimer’s mouse models, human cells, and human brain tissue, the researchers demonstrated that lowering PU.1 promotes the expression of lymphoid immunoregulatory receptor proteins on microglia ...

In Alzheimer's disease, the leading cause of dementia, microglia-the brain's immune defenders-can act as both protectors and aggressors, shaping how the disease progresses. Researchers from the Icahn ...

Silent cells deep in your spinal cord may hold a surprising key to healing after devastating injuries and brain disease. A ...
