Institute member of the Broad Institute

Beth Stevens and her team investigate the role microglia, which are the immune cells, in the brain of mice.  Her studies have shown that microglia play a central role in pruning neuronal connections, or synapses.  Using the mouse visual system as primary model system, she employs a combination of live imaging, molecular, biochemical and neuroanatomical approaches to understand neuron-microglia communication.

Dr. Stevens is exploring the role of microglia in the shaping of connections in the healthy brain, but also in disorders such as autism, schizophrenia and Alzheimer’s disease, which are disorders that could result from microglia pruning too much, or not enough synapses.  One of her current goals is to determine why specific synapses are targeted for elimination, while nearby synapses stay intact.

Dr. Stevens studies have led to a better understanding of the interactions and communication between neurons and glia, both in health and disease.
