Microglia: The Constant Gardeners

A microglial cell (green) from the developing mouse brain is shown as a 3-D image and 3-D computer reconstruction. Synapses from neurons projecting from the eyes (red and blue) are engulfed and seen inside the microglial cell.

A team of scientists at Boston Children’s Hospital, supported by funding from the National Institutes of Health (NIH), uses images and movies such as this one to analyze cells in the developing brain. Read more about this research here.

NIH-supported study shows how immune cells change wiring of the developing mouse brain

A microglial cell in the mature mouse brain Researchers show how immune cells in the brain target and remove unused connections, or synapses, between neurons during normal development. Immune cells known as microglia respond to neuronal activity to select synapses to prune, and eliminate synapses in the way that bacterial cells or other pathogenic debris are eliminated.
