Immune cells chow down on living brain

Zombies aren’t the only things that feast on brains. Immune cells called microglia gorge on neural stem cells in developing rat and monkey brains, researchers report in the March 6 Journal of Neuroscience.

Chewing up neuron-spawning stem cells could help control brain size by pruning away excess growth. Scientists have previously linked abnormal human brain size to autism and schizophrenia.

“It shows microglia are very important in the developing brain,” says neuroscientist Joseph Mathew ...
