A study led by Turkish researcher Pinar Ayata unveiled a critical mechanism involving microglia—specialized immune cells in the brain—that could open new avenues for treating Alzheimer's ...

Others have produced little spheres of human neural tissue by combining neurons, astrocytes, and microglia, all derived from induced pluripotent stem cells. Neurons in this system were more active ...

The study, published in the journal Neuron, highlights microglia, the brain's primary immune cells, as central players in both the protective and harmful responses associated with the disease.
