Alzheimer’s research

Immune mechanisms of synapse loss in health and disease (YouTube lecture)
Beth Stevens, Broad Institute/Boston Children’s Hospital —  July 8, 2015
Her lab is “using a combination of live imaging, molecular, biochemical, and neuroanatomical approaches to investigate the molecular mechanisms by which immune molecules and immune cells called microglia prune synapses in health and disease. Her recent work demonstrates [how] immune-related pruning pathways mediate aberrant synapse loss and dysfunction in neurodegenerative diseases (e.g., Alzheimer’s and Huntington’s disease) and neurodevelopmental disorders, including autism.

Iron-containing inflammatory cells seen in Alzheimer’s brains
“Using high-field MRI technology and staining techniques, scientists have located inflamed, iron-containing scavenger cells in a memory-formation structure in the brains of Alzheimer’s patients who died”
