Cx3Cr1 Expressing Neurons is an important cell type in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
Overview
CX3CR1 (C-X3-C motif chemokine receptor 1), also known as the fractalkine receptor, is a unique GPCR expressed primarily on microglia in the healthy brain. However, emerging research has identified a population of neurons that express CX3CR1, particularly in regions associated with learning, memory, and motor control. These CX3CR1-expressing neurons play crucial roles in neuron-microglia communication, synaptic plasticity, and neuroinflammation regulation. Understanding CX3CR1 neuron biology is essential for developing therapies targeting neuroinflammation in Alzheimer's disease, Parkinson's disease, and other neurodegenerative disorders. [@pabon2023]
