ReviewNeuropathic pain and spinal microglia: a big problem from molecules in "small" glia.
Neuropathic pain is a common and severely disabling state that affects millions of people worldwide. Such pain can be experienced after nerve injury or as part of diseases that affect peripheral nerve function, such as diabetes and AIDS; it can also be a component of pain in other conditions, such as cancer. ⋯ It is important to establish how these molecules are activated in spinal microglia following nerve injury and how they cause signaling to neurons in the dorsal horn pain transmission network. Answers to these questions could lead to new strategies that assist in the diagnosis and management of neuropathic pain--strategies not previously anticipated by a neuron-centric view of pain plasticity in the dorsal horn.
