Microglia are brain macrophages involved in shaping, protecting and killing brain neurons in development, aging and neurodegeneration.  We have been investigating the mechanisms by which microglia become inflamed and damage neurons.  Recently we have found that inflamed microglia can phagocytose (i.e. eat) live neurons, and thereby cause neuronal death and loss. This project will investigating the signals and receptors involved in this process, and whether phagocytosis is beneficial or detrimental in particular pathologies.  The project will use cell culture, fluorescence microscopy and molecular cell biology.
