Microglia, the brain's immune cells, can shift from protective roles to secreting inflammatory messengers like interleukin-12 (IL-12) as the brain ages, potentially accelerating Alzheimer's disease.

Now, two independent studies have honed in on inflammatory microglia as a potential therapeutic strategy. In mice, induction of T regulatory (T reg) cells or supplementation with a metabolic ...

Filopodia are specialized structures that extend from the cell membrane to allow a cell to explore the environment around it. These thin protrusions are full of a protein called actin, which, in ...
