Background

CX3C chemokine receptor 1 (CX3CR1) is a member of the seven-transmembrane G-protein coupled receptor (GPCR) family. It is a receptor for its sole ligand, CX3CL1, also known as fractalkine or neurotactin (1). Immune cells that express CX3CR1 include monocytes, macrophages, microglia, T helper (Th) 1 cells, CD8+ T effector/memory cells, NK cells, γδ T cells, and dendritic cells (DCs) (1,2). CX3CR1 has been implicated in inflammatory diseases, such as nephropathy and macular degeneration, and HIV co-receptors. It is emerging as an important player in the regulation of insulin secretion and beta cell function (3). In the brain, CX3CR1 expression is microglia-specific and regulates microglial recruitment to sites of neuroinflammation (1,2). Disruption of CX3CL1-CX3CR1 signaling promotes neurodegeneration in mouse models of Parkinson’s disease and amyotrophic lateral sclerosis but might be protective in Alzheimer’s disease (AD) (2,4,5).
