Molecular mechanisms: Microglia abnormal in autism brains

Two new postmortem studies show that microglia, which protect the brain from invaders, are denser and more concentrated around neurons in the brains of individuals with autism than in those of controls.

Immune cells sculpt brain by pruning neuronal connections

Immune cells called microglia may play a central role in trimming synapses, the connections between neurons, according to research published 24 May in Neuron. These modifications are part of a normal developmental process by which excess synapses in the brain are destroyed.

Bone marrow transplant alleviates Rett symptoms in mice

A bone marrow transplant from healthy mice to those lacking the MeCP2 protein, which causes Rett syndrome, extends lifespan and alleviates symptoms of the disorder, according to research published online 18 March in Nature.

Scientists capture microglia’s role in brain connectivity

Scientists are changing their minds about the role of microglia, the brain's strongest and most agile soldiers against damage and infection. In healthy brains, microglia help build and eliminate synapses, the junctions between neurons, according to a study published 2 November in PLoS Biology.

Molecular mechanisms: Autism brains show ‘angry’ microglia

A study of postmortem tissue shows that microglia, cells that provide immune protection to the brain, are altered in the brains of individuals with autism.
