To develop male behavior, rats need immune cells
Research reveals unexpected role for cells called microglia in shaping the brain

Immune cells that help heal injuries in the adult brain may have a second job early in life, a study in rats reveals. The brain crusaders unexpectedly moonlight as sculptors, shaping a region of the brain into a male-specific form.
The cells, called microglia, are mobile garbage disposals that travel around the brain and gobble up damaged cells and infectious agents. But the new study, published in the Feb. 13 Journal of Neuroscience, emphasizes that these cells have diverse functions, say...
