Core Tip
Core tip: Edema formation is a major problem following spinal cord injury (SCI) that acts to exacerbate secondary damage. Animal models have become an integral part of understanding this pathophysiology. Several SCI models have been developed, resulting in difficult interpretation between studies with conflicting results. This is true for the role of aquaporin-4 (AQP4) water channels in the development and resolution of edema following SCI. Here, we discuss regulation of AQP4 in varying models and the effect of current interventions on expression, edema formation and functional recovery. Understanding the precise role of AQP4 will help to determine optimal treatments following human SCI.
