EMPhasis on Mutant Microglia: Dysregulation of Brain Sentinels Induces Neurodegeneration

Reactive microglia are often implicated in the pathology of neurodegenerative disease. In a recent study in Nature, Mass et al. (2017) demonstrate that targeted mutation of Braf in early erythro-myeloid precursors (EMPs) causes histiocytosis-associated late onset neurodegeneration driven by activated microglia.
