CXCR4 neurons express the C-X-C chemokine receptor type 4 (CXCR4), a G protein-coupled receptor for the chemokine CXCL12 (stromal-derived factor-1). These neurons are crucial for brain development, synaptic plasticity, and have been implicated in various neurodegenerative diseases. The CXCR4-CXCL12 axis is one of the most important chemokine systems in the nervous system, controlling neuronal migration during development and modulating circuit function in adulthood. [@cxcr2019]
Introduction
CXCR4 is a well-conserved chemokine receptor expressed throughout the nervous system. During development, CXCR4 signaling guides neuronal migration and axonal pathfinding. In the adult brain, CXCR4 continues to be expressed in specific neuronal populations where it modulates synaptic transmission, neurogenesis, and neuronal survival. Dysregulation of CXCR4-CXCL12 signaling has been implicated in Alzheimer's disease, Parkinson's disease, Huntington's disease, and various neurological disorders. [@cxcrsdf2020]
