Cover Story: Complement C5a plays a significant role in regulating inflammation and regeneration upon binding to its receptor, C5aR. Here, we investigated Complement C5a effects on axonal growth of cultured primary hippocampal neurons in a microfluidic device. Our study demonstrated that the neurons express C5aR mRNA and C5aR protein on their membranes. Adding C5a to neurons led to a phosphorylation of their C5aR. When C5a gradient was applied to injured neurons in the microfluidic device, C5a increased the axonal length growth and speed. These findings highlight a new role of C5a in axonal regeneration demonstrating an enhancement of axonal growth after axotomy. While spinal cord injury is a degenerative disease with no effective therapy to restore lost functions, these findings may provide a promising therapeutic tool for spinal cord injury treatment.
