As a consequence of aging, the brain is subject to chronic neuroinflammatory conditions. The resident immune cells of the brain, microglia, act similarly to peripheral macrophages to protect the brain from insults, infection, and physical trauma. However, without proper regulation of their respective host defense mechanisms, these actions can become neurotoxic. In the healthy brain neurons have several signaling systems that directly interact with microglia in order to maintain a calming influence upon their actions, one of particular interest is the chemokine CX3CL1. This chemokine is found predominantly on neurons, while its cognate receptor CX3CR1 is found exclusively on microglia. …
