Cx3Cr1 Gene is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
CX3CR1 (C-X3-C Motif Chemokine Receptor 1) is a G protein-coupled receptor that binds the chemokine fractalkine (CX3CL1). It is expressed primarily on microglia in the central nervous system and plays a critical role in neuron-microglia communication. The CX3CL1/CX3CR1 signaling axis modulates microglial activation, surveillance, and neurotoxicity in neurodegenerative conditions.
CX3CR1 serves as a key regulator of neuroinflammation, acting as a molecular bridge between neurons and immune cells in the brain. Genetic variants and expression changes in CX3CR1 have been implicated in Alzheimer's Disease, Parkinson's Disease, and other neurodegenerative disorders, making it an important therapeutic target.

CX3CR1 is predominantly expressed on:
In the brain, CX3CR1+ microglia show distinct regional distribution with higher densities in hippocampus, cortex, and substantia nigra.
The study of Cx3Cr1 Gene has evolved significantly over the past decades. Research in this area has revealed important insights into the underlying mechanisms of neurodegeneration and continues to drive therapeutic development.
Historical context and key discoveries in this field have shaped our current understanding and will continue to guide future research directions.
